The '''al-Farabi (Alpharabius) quarter-tone''', '''33/32''', is a [[superparticular]] ratio which differs by a [[keenanisma]], (385/384), from the [[36/35|septimal quarter tone (36/35)]]. Raising a just [[4/3|perfect fourth (4/3)]] by the al-Farabi quarter-tone leads to the [[11/8]] super-fourth. Raising it instead by 36/35 leads to the [[48/35|septimal super-fourth (48/35)]] which approximates 11/8. | |||
[[ | Arguably the al-Farabia quarter-tone could have been used as a melodic interval in the Greek Enharmonic Genus. The resulting tetrachord would include 32:33:34 within the interval of a perfect fourth. This ancient Greek scale can be approximated in [[22edo|22-edo]] and [[24edo|24-edo]], if the comma 1089/1088 is tempered so that 33/32 and 34/33 are equated. | ||
