Name

This should be the subharmonic seventh chord, not 1/(7:6:5:4). 1/(7:6:5:4) is a half-diminished chord that doesn't even include a perfect fifth, and the term subharmonic alone isn't enough to signify that as the altering on the fifth should always be explicit. Also, the subharmonic ninth chord 1/(9:7:6:5:4) should extend the subharmonic seventh chord, so if 1/(7:6:5:4) is the subharmonic seventh chord, then 1/(9:7:6:5:4) can't be the subharmonic ninth chord. Finally, there's the neat symmetry that the harmonic sixth chord 6:7:9:10 inverts to the subharmonic seventh chord 1/(7:6:5:4) and the harmonic seventh chord 4:5:6:7 inverts to the subharmonic sixth chord 1/(12:10:8:7). —FloraC (talk) 08:58, 11 March 2026 (UTC)
