Rick, I find it useful to work on projects, and that means one instrument will rise above the others for a while, maybe three months or so. But being a guitar teacher means that I am playing guitar every day, even though it might not be the focus of my latest project. Right now my project is learning to read viol music while improving my bow technique. I'm playing duets with a local viol player who is patient and supportive, thankfully, and in a quartet for the English consort repertoire. I make quite a few mistakes, as we generally sightread, but I'm improving.
After that, I will focus on getting my theorbo improv on ground basses up to scratch, as I can use that when accompanying viols, which would help me become a valuable member of a viol group.
And all the while I am planning another classical guitar recording in a year or so, which means I'm doing enough on the guitar to keep my technique up while musing on a specific repertoire for the recording. When I eventually get around to that, the theorbo and viol will fade into the background.
But, yes, I could do with another five hours in the day, and more energy to use that time wisely!
