Quick question I was wondering if someone could awnser for me-
I was flipping through the sheet music at my local book store the other day and found a jazz fake book that claimed to be for songs in the key of Eb (e flat). According to my understanding of keys, the key of the song is the first note of the scale it's written in. The issue is that, at least to my knowledge, Eb doesn't exist, there's no note between E and F...
Is this some strange Jazz music concept I've never heard of? Or do I just not understand the note circle and there is a note between E and F?
