I have a bassline created for my main groove, but now I want to introduce a new bassline(i.e. same sound different progression for say a chorus style part), how does the 2nd bassline have to be related to the 1st to sound right and be a natural sounding change, I really need to suss this to be able to move on?
I.e. what is the relationship between the two different bassline progressions?
I only play by ear, but understand C D E F G A B and sharps and flats, if this comes into it!
