Greetings from Amtrak. Current location – Syracuse NY, in the dining car!
Recently I re-read a short book I bought in my college years called “Basic Principles in Piano Playing” by Josef Levine. Levine was one of the great pianists and conductors of the 20th century.
Whenever I feel that it’s time to focus on playing and improve, I play Bach – sometimes on guitar, sometimes on piano.
Bach is pretty unforgiving…he wrote what he wrote, and the player has to find a solution. It’s not based on “comfy” positions on an instrument. It presents lots of technical challenges.
