The sinbadmic tetrad is a 13-limit essentially tempered dyadic chord which is a 1001/1000 (sinbadmic) tempered 1 - 11/10 - 13/10 - 10/7 in one voicing, which has steps of 11/10 - 13/11 - 11/10 - 7/5. Equal temperaments with sinbadmic tetrads include 29edo, 31edo, 43edo, 50edo, 53edo, 58edo, 72edo, 87, 103, 111, 130, 183, 190, 198, 270, 571, 590, 643, 860, 1130, 1431 and 1701, with 1701edo giving the optimal patent val.

The name is derived from the sinbadma (1001/1000), a comma that is reminiscent of the tales of 1001 Nights
