It's a concert! Not a service!
So let's add "Deck the Halls" and the Wassail Song! (Seems obvious now, doesn't it?)
So my "old" metronome app (which always worked fine on my Droid) somehow would not make a sound on my new Samsung, I tried downloading some other metronome apps. None of them would sound, either.
This week, got the brilliant idea that, even though it is deactivated as my phone, I can continue to use my Droid as a metronome.
Good practice session this evening; played every note which I am planning to play on the Wednesday, 12 Nov concert, and still had chops. Great place to be, more than a week before the show. Need to woodshed the odd passage, but there is time.
