Here is "Tuning Tune," a grade 2 for string orchestra, in which "A" remains a chord tone throughout. I was having some fun with this one. I wrote it 39 years ago when I was teaching a string orchestra. I don't recall ever performing it. I only recently dragged it out of my files, wiped away the cobwebs, entered it into Finale, and revised it. All the instruments are Finale default bank KS section strings with Garritan Ambience (dry -0.1dB and wet -5.5dB).
I hesitate to call "Tuning Tune" a novelty because the varied dynamics and string techniques provide a lot of teaching opportunities: Playing in tune (that's the "A" part), dynamics, string techniques, maintaining a steady tempo, and blending.
If it's deemed a novelty by the majority here, please, no tomatoes because then the custodial staff will have extra work to do and I'll have to dry clean my tuxedo.
Seriously, as always, I'm eager to hear comments on the music and its presentation.
