I’m trying to figure out if an original arrangement of a public domain song with one bar of similar melody to a cover of the same song violates copyright
long story short, I was in charge of a Christmas cd project, we chose public domain hymns to record so we wouldn’t have to deal with copyright problems
the song that I played on piano has many covers, I listened to some to see what arrangements people had already made, mainly to get some ideas and also to make sure I was being different.
anyways there was one bar in one version that I liked the chord progression of, so I used it but changed it from left hand to right and also switched keys and octaves to give it some variety.
but i just listened to both versions and I’m worried that it still sounds too similar. the cd has been made for a while now and many copies have been sold, so I’m worried that I unknowingly copied a piece of someone else’s work
it’s just that one bar of the song, the rest is completely different
I can’t remember exactly but I think at the time, I didn’t know that a cover of a public domain song had its own copyright
any thoughts would be appreciated.
