Prime 0 Row
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, if the Prime 0 row P0 is given by then by transposing P0 up by seven half steps, we obtain P7:
