I didn't get to work on technical stuff today. But, one thing I did get to work on is "ear training" of sorts and general musicianship.
Today I had a duet performance with blues/jazz artist Gail Storm. We played 3 sets together, with the overwhelming majority of the tunes being ones that neither her nor I have ever done before. It was a great exercise in listening and making sure to do what's needed, musical, and appropriate for each tune specifically, and the gig in general. The tunes that we did that I had zero familiarity with encompassed about 2 hours worth of material.
So, even though I don't normally consider a gig as a practice session, I will consider this one to be a practice session simply because it was really a good work out for my ears, understanding of music harmony and theory, and general musicianship.
