Love music- I’ve played bass guitar, piano and violin- all to various degrees of terrorizing my kitties!
I love music too, my partner is a musician. I can only play a school recorder, when I feel like it not really for the music though more for the movement and the cracking the code of the sheet music.
Heard today that learning a new language can help stave off the effects of alzheimers so might give that a go too.
I completed Rosetta for Latin American Spanish- I really enjoyed it. It didn’t make me conversant in it but , like you said, I enjoyed the decoding aspect!
