Musical scale called "Ishartum" by Lou Harrison, often called the "Flamenco mode", in Pythagorean tuning on E, as follows: (by fifths) F-, C-, G-, D-, A, E, B (F♯+, C♯+, G♯+, and D♯+), or (in order) E (1/1), F- (256/243), G- (32/27), A (4/3), B (3/2), C- (128/81), D (16/9), E (2/1), with G♯+ being 81/64 and D#+ being 729/512. The final F- has an augmented sixth chord, B7b5/F (B D# F A), which resolves to a major chord that touches on the minor third.

Our town was testing the sewers somehow using audio tones to measure something. Maybe resonant frequency or something like that. It sounded vey musical since they were using 3 tones per octave, like a scale based on an augmented fifth chord.
