Decent lesson today despite not having had much of a chance to practice last week -- spouse and one child elected to get sick over the weekend, so taking care of them trumped viola practice. (The nerve!)
Continuing to work on basic coordination stuff (lh fingers always above the fingerboard -- don't let the third and fourth fingers sneak underneath; don't pull fingers far away from the fingerboard even when they come off the strings), cleanliness of bowing / purity of tone (good contact, adequate pressure, using enough bow), and timing (resisting the urge to cut half notes short; using large swaths of bow and bowing more quickly for quarter notes and more slowly for half notes).
My intonation is still far from perfect, but is definitely getting better. It's still shocking that every now and again, I can put my fingers down on the fingerboard without even looking at them and have notes come out in tune! It's pretty wild.
My supervisor keeps musing about possibly taking up the violin. I'm trying to encourage this, since two of our staff have children who play violin and cello, respectively, and that would give us a string quartet. Maybe we could serenade the patrons from the mezzanine of the library; I'm sure that would go over well. =)
