My early teen cousin is learning to play keyboard/piano. She likes to compose her own songs, and she’s good at that, but perhaps could use some help with the basis rhythm.
I thought that a book of rhythms might help. Something like this, but it’s going to be the wrong era for her on the surface, although the rhythms repeat through the ages. Encyclopedia of Piano Rhythm Patterns: Popular Piano Rhythms and How to Play Them https://amzn.eu/d/2JdTsST
Please point me in the right direction. Thank-you in advance
Carl Humpfries’s Piano Handbook and Piano Improvisation Handbook are great, and cover enough for even an absolute beginner. I like noodling around with no previous musical knowledge, and they work very well for that. I think both include pretty decent sections on rhythms, and discuss pretty varied styles.
