Hello
I can give you a perfect piano performance of this Chopin Sonata for your ballet performance - to the sound of a legendary Bosendorfer grand piano.
I am a musician and composer with decades of experience, and a classically trained pianist. I have been playing the piano since I was about three, and I compose much music for the piano.
I have watched your sample video, and can give you the music at the exact same tempo - I have done very much professional music transcription and scoring work, which requires that I work to the exact tempo of recorded music.
It would be a great delight to me to do this for you.
I am happy to discuss a suitable fee and time frame for this task. It is possible that I can complete it in but a few days for you.
Thank you for your consideration
