In music, an all-interval twelve-tone row, series, or chord, is a twelve-tonetone row arranged so that it contains one instance of each interval within the octave, 1 through 11 (an ordering of every interval, 0 through 11, that contains each (ordered) pitch-interval class, 0 through 11). A "twelve-note spatial set made up of the eleven intervals [between consecutive pitches]."[1] There are 1,928 distinct all-interval twelve-tone rows.[4] These sets may be ordered in time or in register. "Distinct" in this context means in transpositionally and rotationally normal form (yielding 3856 such series), and disregarding inversionally related forms.[5]
These 1,928 tone rows have been independently rediscovered several times, their first computation probably was by Andre Riotte in 1961.[6]
Since the sum of numbers 1 through 11 equals 66, an all-interval row must contain a tritone between its first and last notes,[7] as well as in their middle.
