1-I do not read music. Makes it more of a challenge to be learning Psaltery.
I play guitar, harmonica and some Mandolin. I play by ear which means I have to hear it in my head or hear someone else play a song.
I do, however, read tabs. Yes I am one of those folks When leaning a new song I have to tab it as I go along. Long and tedious journey.
Old dog but still learning.
