How many times do you need to listen to a Beethoven Piano sonata to really get it? My dumb ears require at least 40 times to get the feel and flow, the intended tone, and to learn the notes.
I am slow to allow a piece of music (or of anything else) to become a part of my soul. I try to maintain high, discerning walls - which frequently fail.
The sonata form is said to be the core of Beethoven's talent. He wrote 32 piano sonatas, and I have them in a boxed set.
Piano sonata 19 in G minor, opus 49, (like the G-major), was written as a Sonates facile for learners and practicers.
