## Section34.3Writing 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 (P$$\text{}_{3}$$ and I$$\text{}_{3}$$ would begin on E♭, for example) while R and RI forms end on the pitch integer (R$$\text{}_{3}$$ and RI$$\text{}_{3}$$ would end on E♭).

To write I$$\text{}_{9}$$ and RI$$\text{}_{5}$$ if given P$$\text{}_{0}$$:

1. Write all four row forms (P, R, I, RI).

2. Transpose the specified row form to the correct transposition level.

1. In this example, transpose I$$\text{}_{0}$$ up 9 semitones (a major 6th) to begin on A (pitch class 9).

2. To write RI$$\text{}_{5}$$, transpose RI$$\text{}_{0}$$ up 5 semitones (a perfect 4th) so the last note is F (pitch class 5).
