I am an amateur pianist since I am a teenager. I have learned first only by remembering each key, then tried to memorize chords...
Now, I am very ambitious but I allow me years for that project: I would like to understand the music, I keep asking myself these kinds of questions (examples)
Why this chord progression sounds good?
Why using a add9 or maj9 instead of a typical major chord or minor chord?
How can I assign chords myself for a song?
What kind of source would you recommend to me for my project (book,web?) I want to understand what I play, I am ready to study months or years
Moreover, do you know any sources (web, book) where someone analyse score sheet/songs of famous nice song?
Thanks in advance!
