34.3: Writing Row Forms
To write specified row forms from a given prime form, write all four versions of the row: P, R, I, and RI. Then, simply transpose the specified row form to the correct pitch, remembering that P and I forms start on the pitch integer (P3 and I3 would begin on E♭, for example) while R and RI forms end on the pitch integer (R3 and RI3 would end on E♭).
To write I9 and RI5 if given P0:
-
Write all four row forms (P, R, I, RI).
-
Transpose the specified row form to the correct transposition level.
-
In this example, transpose I0 up 9 semitones (a major 6th) to begin on A (pitch class 9).
-
To write RI5, transpose RI0 up 5 semitones (a perfect 4th) so the last note is F (pitch class 5).
-
In this example, transpose I0 up 9 semitones (a major 6th) to begin on A (pitch class 9).
