Below is a 12-tone row generator. Each number refers to a pitch-class (c = 0; c-sharp/d-flat = 1, d = 2, d-sharp/e-flat = 3, e = 4, f = 5, f-sharp/g-flat = 6, g = 7, g-sharp/a-flat = 8, a = 9, a-sharp/b-flat = 10, b = 11). Each time you hit the submit button, you get a new 12-tone row. Like the coin toss generator that I made, this one works through a lot of possibilities; there are 12! rows out there in the universe based on our conventional, equal-tempered division of the octave. So the probability that through a lifetime of refreshing this page you'd get Berg's Lyric Suite row is very low. That row, in case you get it is 5 4 0 9 7 2 8 1 3 6 10 11.

11 4 9 8 0 10 1 7 5 3 2 6
