Introduction: By the way..G.M.I.M.I.T. means.....Graduate Member of the Institute of Musical Instrument Technology....of London.... l have received both vaccines as of March 1st 2021.. I provide excellent Piano tuning, and specializing in regulating the grand piano action so that it performs identically the same way, weather you are playing softly (pp), or loud (ff). You can check it out!! Go to your grand piano or any grand piano, and strike a chord softly (pp) a number of times, and you will notice the hammers will be hitting the strings three or more times as it floats around uncontrollable. And if you strike a loud chord ( ff) and hold it down...then come up slowly... the hammers will pop up and float around before it returns down to its rest position. That is two extra motion that is not required; which means you need to CALL ME.... right now and make an appointment, to have me regulate your grand piano, using the correct sequence of adjustments. Then you will enjoy having full control of the hammers, weather you are playing your piano softly or loud. When l regulate your grand piano...you won't have to have it done ever again...this is a one time adjustment. The cost is only $950. The grand piano of today has an accelerated repetition action. So when I regulate the action, you will never loose control of the hammers during your performance, because I know the proper sequence to regulating the grand piano action. Here is a little about my training.. ....... I am a Graduate Member of the Institute of Musical Instrument Technology (London). holder of the Evelyn Broadwood Scholarship Award for 1968, from the Worshipful Company of Musicians (London); (the first time it has ever been awarded outside of the United Kingdom), also in 1978 l passed the Examination of the Piano Technician Guild (PTG), and now I have over fifty years of experience which will provide you with the Ultimate in service, Integrity, and Professionalism. Call me. Thanks.

Piano Tuning

Working with Calvin was an incredible experience. He is a very talented musician and a craftsman of the piano. I would highly recommend Calvin to any one in search for a piano tuning! 5 Stars for sure

Piano Tuning

I've owned my baby grand for many years. Bought it brand new. However, after Mr. Robertson worked on it and I sat down to play it, it felt like a totally different instrument. It was amazing. He did a complete regulation of the key board mechanics as well as a tuning. He is indeed a master craftsman. The incredible responsiveness of the piano is something I didn't know I was missing until after Mr. Robertson's handiwork. Truly worth every penny and then some!

Piano Tuning

Calvin arrived on time. My piano had not been tuned in a number of years and besides being out of tune, some of the keys stuck. He literally took the piano apartment. He tuned ita and cleaned it. There is not enough words to say how pleased I was with Calvin's work. Besides his professionalism, he was very personable.

Piano Tuning

Outstanding service. Calvin tunes by ear! - something you don’t find everyday. He explained to me some of the processes required to tune old pianos. I feel he really knows what he’s doing.

Piano Tuning

Calvin did an amazing job. Of course it goes without saying that he is going to be my go to person for future tuning. Explained everything to me from the start and he worked diligently on the piano to bring it up to par. It’s sounds great now and feels much better to handle. Thank you for the amazing work. Very professional.
