I practiced Bach's Sinfonia No. 7 on my upright piano and recorded its performance with a PIRECO machine made by KAWAI on 26th November 2023. 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. It would be even more greatly appreciated if you could give me any advice about this performance.
