Q: give me the name of a standard ive never heard before so i can learn its changes on the piano in all 12 keys
A: this is actually a paradox for me. because a 'standard' song is one that is so overwhelmingly popular that everyone knows it. so any standard i could mention, it would have to be assumed that you know it. that being said, before i realized this problem, i was going to say 'tom petty, free fallin'. another good one to learn in all 12 keys will be jock jams y'all ready for this. or maybe you were looking for something more difficult, in which case i would say babylon sisters
