I would like to learn to properly improvise on the piano, but I can't find a physical book that will help me improve my skills. I know of Carl Czerny's book "The Art of Improvising" (not full name but not important), but the only translated books in English I can find are online on IMSLP or Scribd. This sucks because I prefer not to have a screen right in front of me to read a book. It hurts my eyes. TBH, I could print it out from a printer, but that's just a waste of paper and ink. So can anyone recommend me a physical book that I can buy on improvisation?
What style do you want to improvise in—classical or jazz?
The foundation of improvising is harmony/theory. Have you studied theory?
Also, do you sit down at the piano and tinker? Carve out a melody; try to put some chords to it?
Sometimes, but not currently, because I am focusing on practicing and getting good at pieces to expand my repertoire. I have done some interesting stuff on piano, I guess.
