how do i go about this? are piano classes expensive? can i just learn at home from the internet or rent a book?
It is possible to learn it by yourself, but you need to have a good ear and a good grounding in music theory. Experiment a bit; play something and if it sounds familiar, try figure the rest out. Also, learn about intervals. This can improve both your ear and your theory…
Admittedly, im not the greatest player at the moment, but ive gone pretty far with next to no instruction.
(Can NEelse here play Bachs Tocatta & Fugue? From memory? Dont think so…
