I am a multi intrumentalist..I play sax. trumpet, harmonica,Trombone. guitar, banjo, tin whistle, tenor horn, baritone horn, euphonium and flugel horn.. I sing as well and do harmonies and backing vocals, but primarily I am a drummer. I learned to read music when I was 7 years old.I started playing guitar back in 1980… I started with three chord CFG or GDE chord songs. the first 4 chord song I learned was You’ve got to hide your love away by The Beatles which had a D in it… I have even played in bands on acoustic guitar but I STILL can’t play a B chord after decades of gigging..so … practice makes perfect clearly dont apply in this case… ANY IDEAS?
