I've just started learning my music theory etc and I've got a few basic questions, just to ensure I've got things straight (Bare with me as these questions are very very basic, but if you never ask you never learn hey!) Am I right in assuming that if the guitar (or whatever instrument) is playing a C major chord then we can use any notes from the C major scale to create a bassline? Same goes for the minor scale, i.e. someone playing a Dm chord, we can use notes from the Dm scale? Same again with the triads, if someone plays a C Major we can simply use the notes of C major triad to create our bassline? Lastly, I've learnt about Major, Minor, Dominant, and Half Diminished 7th chords. If someone is playing a G7 chord, we use the notes from the G dominant chord to make the bassline? etc I guess that all that is correct and that I have it all sorted in my head, I just want to get some input to ensure I'm looking at things in the right way! Any help appreciated!
