Hi! First I search for the piano chords of the song then I apply it in BandLab, if the song is new or it has no available chords online I use an app that determines the chords of the song, it's "Chord Ai" App.
Can you teach us how to use the settings and what all the musical key words mean, so that we can create our own instrumentals and understand how everything works, pls :) ♡
