As a part of my academic thesis, I have to build a device that helps pianists during their performance. Before testing that with real pianists, I must adjust and regulate that device.
I have to play piano (up to grade 4) and I know that the process of learning piano is not easy. Is there a fast training process for learning play piano up to grade 4 in 3 or 4 months?
I am almost 40 years old and I played some instruments before.
