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.
