Me and a buddy have worked up some southwestern tunes lately, that are usually played with twin fiddles doing harmony. I'm playing the second fiddle parts on guitar, and now I've started working on harmony for other fiddle tunes. I record the tune melody and then loop it while I try various harmony approaches.

In bluegrass sometimes its hard to keep the chords in mind when I'm taking a break - especially if I just learned the tune. But it feels like this harmony thing is helping with chord awareness and unlocking some interesting sounds even in my solo break playing.

Anyone else have this experience in harmony playing? Or have other ways of keeping the changes in mind during breaks.
