I've dealt w/ guitarists my entire life (i'm 29).
I might have a new guitarist.
(I'm a singer)
I sang to him the latest song I wrote. My song is in the key of F# a capella, and it's that way the whole way through.
This guitarist plays F# E B A for almost the whole time. The second and fourth chords of the verse, are both kind of off-chords, not a part of the standard key (2nd chord is an Emaj of some sort and the 4th chord is an Amaj of some sort. neither E nor A is in the F# scale). I heard it's not an uncommon chord substitution in that kinda structure, often in rock songs and the such I guess. But does it really work if I, the singer, writes the melody first? Must i change my melody? Guitarist says think of it as F# lydian (or B major) and then it's "in key". Another guitarist says, "Why would I have to think about it a certain way for it to be in key? Your song is in the key of F# as ionian, and that's a fact. The Bmaj is fine and is in key. It's the E and the A that are NOT in key, and that's also a fact. If he was writing a song for himself with those chords or y'all were to write one together with those chords, that's a different story, because the melody can jump keys easily. I'm not trying to invalidate his chord progression entirely but for him to put that chord progression together and blatantly neglect the key of the melody you're ALREADY in really grinds my gears."
Here's the song:
