About Kelvin L.
I am a highly organized, outcome-driven and motivated professional musician and educator with solid experience in the classroom. For the past 25 years, I have been employed with Amati music academy and seven years on the faculty of University of St Francis.
I am very comfortable with all aspects of the current music syllabus, including teaching musical concepts (such as duration, pitch, dynamics, tone color, texture and structure) as well as performance, composition. I am fully qualified, with a Bachelor of Education in Music, Double Masters in music performance and education from University of Nottingham.
I am proficient in classical, jazz and Celtic fiddle violin and possess solid skills in piano (grade 8-13) Royal conservatory system.
Throughout my teaching career, I have been driven to help students achieve their very best. I strongly believe that music has the power to change lives – to enhance the social, cultural and spiritual lives of people, and serve as a profound medium of personal expression. Professional perform experience: The Chicago, Natalie Cole, Smokey Robinson, Three tours with Moody Blues, YoYo Ma etc....
The most important thing I look for in a student is communication skills, as well as talent. I like to nurture students and help identify their individual strengths, which is a key factor in shaping a musical persona that will make its mark both on and offstage. I do not advocate a uniform technique for all students. Physical differences and learning styles are always taken into consideration. Potential is as important to me as early achievements and experience. My goal is to help students become self-sufficient, discriminating artists. I discuss practice techniques often and develop individualized scale routines. I encourage initiative and expressive musicality as well as precision. Above all, music needs to bring obvious joy to the student, regardless of the difficulties.”

My work schedule has interrupted my lessons for a while now, but Kelvin is a kind hearted instructor who truly believes in developing his students.
I will continue lessons with him as soon as I can.
Very patient with my 4 year old! Kelvin is very skilled beautiful pianist !
Kelvin is a phenomenal teacher of classical guitar. Our teenage son wanted to take classical lessons for a while, after having happily done a couple years with School of Rock. He and Kelvin meshed well, and I feel our son learned a lot over the course of a couple more years.
When one of us had a schedule conflict, we had the ability to do a lesson via Skype. Let me tell you, that came in mighty handy in the winter of 2019.
Schedule with Kelvin; I am certain you'll be glad that you did.
We love Kelvin, he is really patient and talented on teaching drawing.
The Best Teacher you could ever have . Its a great privilege to be one of his student .
Excellent first lesson with Kelvin with my 12 year old son beginner.
Kelvin was very professional, knowledgeable and accommodating! Wonderful teacher!
My first lesson with Kelvin and he was quite patient with me. I really enjoyed having the lesson. The time passed quickly.
Kelvin has taken me a long way in a short time. So grateful!
Always great lessons with Kelvin!
Great lesson! We got so much accomplished during this time! Look forward to next week.
Had a great experience with Kelvin. Looking forward to the next lesson!
Kelvin was great! I learned allot in a short time. Thank you. Joe
Rich was happy after the first class and he started to wonder, would Kelvin be available to teach him a guitar lessons as well (we thought it is a great beginning) :)
Also, Kelvin immediately pointed out that the violin we have picked is too small for Rich, where other teacher didn't say anything about it. We changed the size and it helped a lot with holding violin and feeling more comfortable. Thank you !
Kelvin is a great teacher. He understands and teaches in a way that makes sense to me. If you’ve played the Banjo you know the teacher needs a lot of patience and he does. He provides the right direction and more importantly listens to my questions. There is no doubt in my mind if you have to learn or improve your banjo skills Kelvin can help.Show More
Very pleasant , very intuitive , and very encouraging. He cares and tries hard to accommodate and customize his teaching.
Kelvin is knowledgeable, patient, and has a good grasp of the subject. He communicates well and generates enthusiasm. His style motivates a great deal of interest. We developed a very good rap-ore
There were scheduling issues due to system glitches. However, Kelvin is very patient and worked with me to make sure my lesson took place. I’m so glad he was able to accommodate my schedule because I really enjoyed my lesson.
Is helping to teach musical theory to my son. Very good
Very Good with my son who has ADD
I had my first lesson with Kelvin and it was very good. Kelvin made me feel very comfortable and we focused on the various tones used in learning and speaking Mandarin. I look forward to my next class this coming weekend.
Great start. No doubt a professional instructor. Looking forward to learn.
Very clear and patient.
Ok apart from a blury connection
There was a delay of about 10 seconds, but everything else was amazing
The audio and video were fuzzy at times, so he did not always know what Kelvin was asking him to do....so that is the missing star. Other than that he enjoyed the lesson very much.
I think personal face - face classes for painting would help better than online.
Kelvin had a great personality and is very knowledgeable. In the first lesson, he showed what was possible in Photoshop and Lightroom.
I feel misled.
Kelvin is excellent.
Enjoyed immensely! Kelvin is talented, energetic, experienced and very encouraging!
My son just completed 3 piano lessons with kelvin. He is enjoying his lessons so far. Kelvin is patient and very talented. He is very knowledgeable in all music. I am very excited to have found him and looking forward to working with him for many years.
Very pleasant 1st time meeting and great tennis lesson with my son. Excellent style for teaching my 14 year old.
Good lesson today
He is very patient with me. Thank you.
Friendly, engaging, supportive...look forward to future lessons.
Kelvin is very personable and truthfully critiques your skill based on the level you should be at. I look forward to the class sessions and enjoy practicing what I'm being taught.
Was not the match for me.
Our first lesson was amazing. He is very kind and patient and has a great personality. We are excited to have found him and can't wait for next weeks lesson
Our first lesson was amazing. He is very kind and patient and has a great personality. We are excited to have found him and can't wait for next weeks lesson
We loved our first lesson! And our son really liked Kelvin. He made him feel excited and enthusiastic to learn more cello and to improve.
Kelvin was very helpful and encouraging.
Had a great 1st lesson with Kelvin. My daughter was happy with the lesson. Kelvin gave great direction on what she needs to work on.
We had a lot of fun.
Kelvin has a great way of getting the most out of my playing and inspires me to do better. Very encouraging, very enjoyable!
I have really enjoyed my drawing lessons with Kelvin! He is very detailed in his instruction and ensures that his students learn the essential skills necessary to become good drawers. He is very encouraging and honest in his feedback. I appreciate his transparency when critiquing my work. I need to hear the truth in order to get better. When I draw something that he is astounded by, I will know that I have truly earned his respect. My lessons fly by because we're having such a good time. I'm enjoying the journey.Show More
Kelvin is a talented, caring and effective teacher, able to spot technical, as well as musical, errors online. It has been a pleasure to take lessons from him - and I have progressed well beyond my expectations thanks to his expertise. I highly recommend him.Show More
Kelvin did it again! He supported and prepared my son for his orchestra audition. Nicholas was accepted into the Metropolitan Youth Symphony Orchestra for the third year in a row. Kelvin has helped him to achieve this goal each time. Thanks Kelvin for being such a great instructor and truly investing in my son.Show More
Kelvin was a nice guy but not very good at listening. You can tell he is probably good at SEO, but is more geared towards giving multiple lessons, because he will not answer any questions if its not in the order he is teaching. Being a teacher myself, you have to LISTEN to the person paying for the lesson. You should not tell a paying customer that you wont answer a question because you will get to that at a later time in a different lesson. Some people, like myself understand many aspects of SEO already, and just need to ask some questions to learn new things to try.
Kelvin did give me a couple very good tips I will implement.
You could be a very good teacher my friend, just listen more
Kelvin is an extremely knowledgeable musician with a great teaching style.
Kelvin is a very patient teacher! I knew absolutely nothing about mandolin or music and Kelvin has helped with that. I have a long way to go but, with Kelvins help I believe I can get there!
I highly recommend Kelvin!!!!!
When we were looking for a piano teacher for our 13yo daughter we were looking for someone who could also help her out with her church music as she is the "organist" during school masses. Kelvin was more than willing to do so. She has learned more in four lessons with Kelvin than she did in more than two years with a another teacher. Kelvin is very patient and makes each lesson fun. At the same time he is demanding without being strict. We are all very pleased with Kelvin's method of teaching. We highly recommend him.Show More
The class is great.
Kelvin narrows in on exactly what needs work. He is great to work with and I'm looking forward to practicing with his advice and my next lesson.
My first meeting with Kelvin was great! He is very knowledgeable and makes the learning experience fun. Thanks Kelvin, I look forward to the next lesson!
Kelvin is an outstanding musician and seems to be able to play practically every instrument in existence. He is very knowledgable about all music and the best way to play each piece.
Great Kelvin made my lesson fun learning the forward and back roll. Can't wait for my next lesson. Got to go, practice time.
We were very fortunate to find Mr. Kelvin. My son has taken piano lessons with him for 2 years now and I am very impressed with what he has learned in that short time. I think Mr. Kelvin is encouraging, kind, strict, and expects him to always do his best. These characteristics of his, is a perfect combination that has motivated my son to learn and enjoy his lessons.Show More
Mr. Lin was/is fantastic. I have absolutely no musical background and I left the first class even more excited about learning than when I arrive. Mr. Lin stressed the basics and insured that the topics covered were well reinforced. His teaching style is VERY user friendly while still maintaining a professional learning environment. Maybe if I had a teacher Like Mr. Lin when I was in Jr. High, I would have stuck with music. Instead I have waited over 40 years, but it would seem that scoring a teacher like Mr. Lin was worth the wait.Show More
So far so good! (3 lessons) Kelvin is patient and a good listener.
I purchased 5 lessons for my better half to see if she'd like the instructor. Went for our first meeting during a snowstorm and he was very nice but spent way too much time talking about non guitar related stuff and conversated with me as much as my better half. In any case there were some scheduling issues due to him going to China and later saying he could not do Saturdays all the time which was fine. We scheduled some more sessions. TakeLessons policy for cancellations is 24 hours and that's what he told us while we were there. This cancellation policy was also reflected as 24 hours on his page on TakeLessons. After speaking with a TakeLessons representative (Michael), according to the rep, Kelvin was supposed to have us sign a 48 hour cancellation policy and he never did. As a matter of fact during our first session he said the cancellation was 24 hours himself. Due to another situation we cancelled our next session within the 24 hour cancellation window. We were charged for it and told by him that his cancellation policy was 48 hours and that he had told us this in advance. This was false. I'm disappointed with both Kelvin (who I might add may truly believe that he informed us of his personal policy) and TakeLessons. TakeLessons representative Michael called me and left a message stating that he spoke to Kelvin and because Kelvin said we were informed of the 48 hour policy that they could not do anything about it. Not sure why it's worth lying over $40 but I figure he truly believes that he told us of his policies but he did not. What is more disappointing is that the TakeLessons rep Michael told me that Kelvin made clients sign the 48 hour cancellation policy as a requirement and he never did. Hence he has no record of one. You would think this would automatically be a clear indication that something was not right but they just chose to take his word for it over ours. In any case, buyer beware of dishonestly by Kelvin and operational ineptitude by TakeLessons to implement systems in place to make sure the buyer is protected as well.Show More
Kelvin is very patient. He helped my son get rid of his mental block, and he is very comfortable with drawing now. He is a great teacher!
I was very excited to be taking lessons, I played when I was a little girl, & my husband knew this & bought me a violin for Christmas so I could play again... but I was nervous if I would be able to learn since I'm not young! Mr Lin is a great teacher, he is very patient, & made me feel very comfortable... and I'm teachable! Yeah! I did good... I'm going to keep practicing, and can't wait for my next lesson!Show More
As an older beginner, Kelvin made me very comfortable. Looking forward to our next lesson.
Very enthusiastic and helpful. Encouraging and engaging.
I have studied violin with Kelvin for over a year, and have had an amazing experience being able to learn from one of the best violinists I have ever met. He is incredibly patient and kind, and has taken my playing to a whole new level. Highly recommended. Truly a one of a kind teacher.Show More
I have been studying with Kelvin for 2 and 1/2 years. I chose him because he was the highest rated teacher in my area. The rating is well deserved. I have found him to be an excellent teacher: patient, respectful, encouraging and extremely knowledgeable. I am well satisfied with my progress, especially since I had no prior musical instruction and yet was ambitious enough to take up the piano at the age of 67. I expect to continue with Kelvin for the foreseeable future, as I have not yet found the limit of what I can do.Show More
great first lesson!
AWESOME!!, AWESOME!!!! Great teacher, takes his time and goes at your own pace. I will continue taking my lessons with Kelvin.
Kelvin is the best instructor for music that i have ever had. he is very nice and welcoming for any student.
My son had a great first lesson. We are excited for next week.
Kelvin is a very good teacher always trying to meet students where they are.
I had a great first lesson with Kelvin! He's fast and efficient and knows how to maximize the online time slot! This is gonna be fun!!!
Kelvin is an awesome teacher. I wanted to learn to play by ear, because that's the way I learned to play the guitar. I had been looking for a teacher for several weeks, and after contacting several teachers, most of them didn't respond. The one who did respond refused to teach me without sheet music. I was about to give up the whole idea of playing, but Kelvin took me on and has developed a method of teaching me without the burden of having to learn to read sheet music. My playing has improved with only four lessons! I highly recommend him as a teacher!Show More
First Lesson went great. Kelvin is very encouraging. The amount of things we covered in the first lesson seemed appropriate. Not an overwhelming amount of info, but enough to keep me busy practicing until the next lesson.
Our experience has been excellent. Kelvin's lessons are a challenging supplement to my son's school orchestra program. We also appreciate Kelvin's quick response to email and accommodating a few short notice notice schedule changes. My son enjoys his weekly Skype lesson and seems to be making great progress. We highly recommend Kelvin Lin.Show More
I bought guitar lessons as a Christmas present for my Dad and he loved his lessons from Kelvin! He said Kelvin was a great teacher and catered the lesson perfectly for my Dad's level and what he wanted to get out of the lessons.
My 13 yo niece took video editing/production lessons from Kelvin. He kept her interested & engaged. He explained things well & in a way that she could clearly understand. She was eager to do the homework he gave her and to go to the next class. I recommend Kelvin highly. He's a fantastic teacher.Show More
We are very fortunate to have Kelvin as our daughter's violin teacher. He makes learning fun and interesting. She looks forward to her lessons. He's very energetic and is able to keep her focused. We appreciate that he's very patient and addresses any concerns she may be having with her music.Show More
Mr. Kelvin began teaching my daughter when she was 4 yrs old...a year later she is able to recite notes and integrate and apply her knowledge of music theory to her music pieces. Mr. Kelvin is very enthusiastic every practice, but most importantly he is VERY patient and adaptable to my young daughter's mood...especially for a 5yr old who has a small attention span.Show More
Kelvin was very kind and supportive of what I wanted to accomplish. I look forward to continuing on my Chinese lessons with him.
Kelvin is amazing! Very patient and he really helps me feel comfortable and confident that I can master playing the Violin in no time! Thanks to him, I'm constantly improving and learning how to play the RIGHT way!
Great instructor and teaching method. Gave my 11 year old lots of confidence.
Mr. Kelvin is very professional. He is teaching my 3 kids with different approach uniquely designed on their age level. My kids love him and they enjoy every lesson.
Kevin is helping our son with drawing skills and the improvement is outstanding! Excellent teacher and just what our son was looking for
Son very happy!
Kelvin is so great at catering to each students needs and keeping the lessons light and fun. He is so full of fun stories and encouragement as well as being a magnificent teacher.
Instructor with vast experience, I really enjoy learning from him
Outstanding, quite talented instructor with very broad experience
Mr. Kelvin is a passionate musician, best that I've known. His lessons are not boring and always go by in a flash. He is good at identifying problems that needs correction and he will point them out consistently until rectified. Highly recommended if you are looking for a teacher to give you pointers to bring your music up a notch!Show More
Mr. Kelvin demystifies Lightroom and the layering process. He has taught me how to edit with ease. He makes sure you understand what he has done before moving on and is generous with his time when you have questions. Whether you are a beginner or a pro, Kelvin moves at YOUR pace and does not move on until you fully understand the task at hand. I will continue classes with Mr. Kelvin for the foreseeable future. He is a pleasure to work with. He is a very intelligent, kind and understanding mentor. I would recommend him to anyone. :)Show More
Kelvin is an accomplished and effective teacher who makes online lessons both enjoyable and stimulating. He quickly spots bad tendencies so that they can be corrected early in the process and thus prevent future problems. Kelvin is personable, professional and knows what he's talking about. I look forward to each lesson to see what the next challenge will be and to get to spend time with Kelvin.Show More
Mr. Kelvin is a very skillful musician and a passionate teacher. Just a couple of months into learning piano, the 30 minute weekly lesson at Mr. Kelvin's studio became a fun activity my 5 year old daughter is enjoying every week. I can tell that she is having fun every time at Mr. Kelvin's studio, and she just loves learning piano there.Show More
Very good teacher, with a lots of compassion.Mr. Kelvin is paying attention to details which makes my daughter better violin player.
Kudos to Kelvin! He played an integral part in preparing Nick for his audition with the Metropolitan Youth Symphony Orchestra in Atlanta. The best part is that Nick passed the audition and will be joining the orchestra later this month. Kelvin and Nick have a great connection. He truly supports my son's love of music.Show More
He's very helpful
I was ready to get my money back until Take Lesson set me up with this teacher. He is amazing. So interested in the students life and takes the time to structure the lessons around what the student is interested in. Truly an amazing teacher.
A real professional
Kelvin is an amazing teacher whose love for music truly shows. His knowledge is beyond the normal music instructor and shows when organizing all my kids in the living room to play music together. It's a real treat to hear them all working together!
Mr. Kelvin is amazing!
Mr. Kelvin is an amazing guy. He teaches in depth, and the classes were very flexible and insightful. I was inspired by his passion of music, knowledgeable techniques, and his enthusiasm. Violin is a powerful instrument and I want to learn as he'll teach me. There's quality in his teachings, and I if you choose Mr. Kelvin, you can trust that you'll learn good habits and have encouragement every step of the way. I couldn't have chose better.
Kelvin has been an excellent instructor for our daughter. He is articulate in a friendly and informative way. She enjoys her online lessons with Kelvin and has improved her technique within months. He has discovered and adjusted the unhelpful habits that she has developed over years of study. The improved quality of her playing has not only lifted her confidence and inspired her to keep practicing, but it has been recognized by other instructors as well.
Thank you Kelvin!
Tremendous improvement in technique
Kelvin is a tremendously gifted musician and instructor. He has increased my level of confidence. He continues to push me to my fullest potential. His lessons are very thorough. I most appreciate the encouragement he gives me to use my talent. He is both patient and kind. I recommend him highly.
Simply an amazing teacher
I've always wanted to play Violin but was always intimidated by the instrument, especially when I finally bought one and picked it up for the first time.
My intimidation went away when I started taking lessons with Kelvin.
Kelvin provided all of the necessary steps and guidelines along the way from my first note to my first song and did it with many examples that I can perfectly relate to.
He keeps things simple yet very complex at the same time.
The way he teaches is very easy to understand.
He can instantly notice a mistake if I've made one and he is able to correct it easily.
And through all of this, every lesson I take with him is very fun and exciting.
Kelvin is truly a professional and it is wonderful to be able to learn to play violin from him.
I Would Recommend Kelvin to Anyone
I am 67 and never had music lessons before. Iâve been studying the piano with Kelvin for about 7 months now. I think Kelvin is a good teacher because:
- He never says âthatâs good enough.â He has high standards and if there is anything lacking in my performance, he makes sure I know what it is.
- He is very encouraging, and when he tells me Iâve finally got a piece right, I know that means something.
- He is always pushing me to do a little better. (Not too pushy though.)
- He is very good about correcting my technique and explaining why things are done a certain way.
I intend to continue lessons with Kelvin for the foreseeable future; and I would recommend him to anyone who is looking for a music teacher.
An excellent and talented piano teacher and musician
Kelvin has been providing lessons in our home for a few months. He is punctual and extremely professional. My teen stopped taking lessons for a couple of years but has enjoyed picking up this instrument again because of this teacher. Thank you!
Mr. Kelvin is a wonderful teacher. His patience and expertise with younger children is such as asset. We would highly recommened him!
Each lesson with Kelvin is fun and upbeat.
Although many miles apart, Kelvin has fostered a productive, professional relationship with both me and my 8 year old daughter. His ability to connect with her via Skype is a testament to his experience and good-nature. Kelvin praises her smallest achievements at every lesson and encourages her to excel. He teaches her to think beyond the notes on the page and takes every opportunity to make learning an instrument relevant to the real world. Each lesson is fun and upbeat. He is committed to her success and we are very lucky to have such a dedicated teacher.
I have been study with Kelvin for almost 6 and half years, I am glad found an excellent instruction by a very professional teacher.but be ready to learn more than just Music. and be ready to be more successful in your everyday life oh and I have been to other music teachers. they don't compare..
Thank you Kelvin! you have made me become a great fiddler!
A wonderful experience
My daughter is 14 years old, is on the lower end of intermediate ability for piano and has a background in clarinet. Kelvin was wonderful. A great all around teacher. From technique to conveying confidence to teaching you how to convey your emotion through your music, Kelvin does it all. What a wonderful teacher!
Great pleasure working with Kelvin
Kelvin is not only an amazing, kind-hearted, smart and trustworthy person but he is also one of the best musicians I have seen around the Chicago area. I have been in the music business for most of my life having taken many violin and piano lessons from different people and Kelvin has to be the most patient musician I have collaborated with yet. I recommend Kelvin to anyone looking to learn to play music - young - and - old. He is extremely passionate about music and continuously never fails to inspire me.
The most honest and straightforward teacher
Kelvin's unparalleled enthusiasm for life and music shines through in his playing and teaching style. He shows a strong proficiency in many different styles and on multiple instruments.
He's reliable, experienced, professional, and a great guy all around. One of Kelvin's main strengths is his ability to convey a given subject matter in a way that is meaningful, constructive and easily understood.
I'm also a music teacher (private lessons and in the classroom) as well as a professional performer. I've found it to be a great pleasure working with Kelvin and I would strongly recommend him as a teacher and a performer.
Kelvin is a great teacher. He has a hands-on teaching style integrated with little bits of music theory. Also, he gives you constructive criticism on your originals that doesn't insult your artistic style, but rather works with it. When I first found Kelvin, I told him I wanted to learn an array of instruments so I can understand the workings of a orchestra before I assemble one of my own, and he was in full support of it! Over the course of several lessons, we've listened to several CDs and analyzed the arrangements listening for the entrance of different instruments that add complexity and depth to the music. Kelvin is the ideal teacher for learning the general concepts behind building a song, and learning specifics within songwriting. Assuming you dedicate enough time to your music between lessons, Taking lessons with Kelvin has been the best investment yet on my musical journey.
Professional, Knowledgeable and Great Educator
Kelvin is an excellent violin teacher. The violin lessons are professional and educational as well as fun easy and exciting. When Kelvin perceive something that needs to be corrected or something that I need to work on, he does it with such helpful analogies and simple instructions that it is easy for me to work on my skills and correct the problem. After each lesson, I always leave with more violin knowledge and techniques than I came with. Kelvin's way of teaching has helped me develop and improve my skills as well as giving me a good solid foundation as I continue my journey on mastering the violin.
A great educator and learning enviroment
All two of daughters take violin lessons from Kelvin. He's been a wonderful addition to the community. He has a great level of patience and natural way of connecting with young children.
The girls also enjoy the community aspect of Kevin's program as well as the opportunity to perform the pieces of music that they work so hard on mastering.
They both made into Chicago youth symphony last year.
A wonderful teacher who cares his students
I have been taking violin lesson with Kelvin for ten years now...my sister also studied with him since she was 7 years old...got her full scholarship at Indiana university with music major.
He is very professional, great communication, very patient and very encouraging
A great instrument to express a emotion
A well self explanatory teacher I am enjoying the lessons looking forward to become a pro in piano.
