Here’s what I am trying to do… I have a melody, of an existing song. Just the melody of the main voice, no backing chords/arpeggios. But I want to derive proper backing chords, given the scale of the main melody. For example, I have a song that is in F# minor. But I only have the main melody. Now I would like to create some backing chords, but not manually. I keep thinking now that I know the Scale, I should be able to lock in the Scale and somehow map the incoming melody notes to Scaler’s key binding to chords in the scale.
The challenge is that Scaler’s keybinding relies on C,D,E,F,G,A,B to trigger the chords I,II,III,IV,V,VI,VII in the scale. But the melody notes come in as notes in the F# minor scale. How could I remap the F# minor notes to C maj, in which Scaler’s key binding works?
I feel this should be possible, but it’s too early morning to think too hard. Perhaps I will end up answering my question later
