Sage Walker it is, my friend, until you say otherwise.One thing that happens a lot to me is that I compose a tune, only to find later that it is a nice harmony to a tune I already know. Works out OK either way. My best tunes come when I'm playing fingerstyle guitar, I guess because the harmonies (as from one note to the next) are easier to realize and play with. Then I transfer them to other instruments. Usually starts with a small piece of a tune, and if I think about it, throwing in intervals from the emerging chords, as well as well-placed accidentals, usually leads in interesting directions.
