In my 2008 piece for Greek Byzantine choir and strings, Nativity Kontakion, I discovered a beautiful harmonic structure based around the Byzantine whole step you get when you divide the octave into fourteen 72nds — a bit wider than the whole step on the piano, which is twelve 72nds of an octave wide. Invert that wide “14/72” whole step, and you get a minor seventh narrower than the usual one. It so happens that this narrower minor seventh is almost equivalent to the seventh partial — one of those pure, God-made mathematical ratios that fell out of favor when equal temperament took over.
Everything that was once old becomes new again. First it was vinyl and now we want to make a case for a medium that quite frankly doesn’t get enough love — the cassette tape.
