All-trichord hexachord

All-trichord hexachord trichords.[1]

In music, the all-trichord hexachord is a unique hexachord that contains all twelve trichords, or from which all twelve possible trichords may be derived.[2] The prime form of this set class is {012478}[1] and its Forte number is 6-Z17. The following is an example of the all-trichord hexachord.

{
\override Score.TimeSignature
#'stencil = ##f
    \relative c' {
        \time 24/4
        \set Score.tempoHideNote = ##t \tempo 1 = 160
        c1 cis d e g aes
    }
}

Its complement is 6-Z43 and they share the interval vector of <3,2,2,3,3,2>.

It appears in pieces by Robert Morris and Elliott Carter.[3] Carter uses all-interval twelve-tone sets consisting of all-trichord hexachords in his Symphonia: sum fluxae pretium spei.[4]
