List of pitch-class sets
This is a list of pitch-class sets by Forte number. For a list of ordered collections, see: list of tone rows and series. Sets are listed next to their complements. Inversions are marked "B" (sets not marked "A" or "B" are symmetrical). "T" and "E" are conventionally used in sets to notate 10 and 11, respectively, as single characters. There are two slightly different methods of obtaining a normal form. This results in two different normal form sets for the same Forte number in a few cases. The alternative notation for those chords are  listed in the footnotes. Elliott Carter had earlier (1960–67) produced a numbered listing of pitch class sets, or "chords", as Carter referred to them, for his own use. Donald Martino had produced tables of hexachords, tetrachords, trichords, and pentachords for combinatoriality in his article, "The Source Set and its Aggregate Formations" (1961).
