Despite sharing the same Great-Grandmother,Will Fly and I play very differently ! He obviously knows his music theory,and I don't ! I have tried and tried , but to Noah Vale ! I have some sort of musical dyslexia that maliciously and mischieviously prevents me from reading music or understanding music theory , and have learned to play "by ear" all my life ; I play guitar now exclusively in double-dropped D , and have "discovered" a great many chords the names of which I can only guess at ! However ,this disadvantage bothers me not a jot , and I will happily play for you from an extensive repertoire that includes pieces from Playford,The Hardy Manuscript ,Fred Paris,Wim Poesen,Roger Tallroth,Carolan , et al .If it was OK for Hoagy Carmichael, then it's OK for me ! ( and you , probably ).
