I practiced Bach's Sinfonia No.8 on my upright piano and recorded its performance with a PIRECO machine made by KAWAI on 05.07.2024. Tuner Mr. Takahiro Natori installed an action modification package called "Grand Feel" provided by Fujii Piano Service on a Yamaha UX1 upright piano. Thank you very much for listening. At the moment I can't play any more lively and faster, but I'll get used to it soon. I don't know if this is the right point to stick to, but this time I played without damper pedal. It would be even more greatly appreciated if you could give me any advice about this performance.
