The original row of the piece is known generally as the Prime 0 row ("P0"). Basic transformations
of an ordered series of pitches are transposition, inversion, retrograde, and retrogradeinversion.
In this modular 12 system, a set of pitch
classes may be transposed by adding a number from 1 to 11 to the original row, such that any sum equalling 12 or greater
will be reduced by 12 (e.g., For example, with the Prime 0 row P0 given by then by transposing P0 up by seven half steps, we obtain P7:
