Quartet for Strings No.12

Frankly my primary thought at the moment is remembering Beethoven's 12th, Op.127, was an opening salvo in a Late Period that helped completely revolutionize Western musical styles ... about 70 years after his death. Until then, it was widely understood to be an unfortunate product of dementia brought on by the profundity of his deafness at the time. Any evidence of dementia in this, my own humbly submitted 12th string quartet, is doubtless more correctly diagnosed; potent testimony to which is the contention that - at least according to my understanding of Hindemith's harmonic theory - every measure of this piece displays an identifiable (non-diatonic) tonal center in a progression following the root position of the underlying tone row itself:

(1)C (2)Db-E-A-Bb-Ab (3)Gb-G-F (4)Eb-D-B.

All of which theoretical bubble-blowing is of course irrelevant to the main point; and I am too close to the work's production to reliably judge anything about that. I did what I could.
