• Every piece of 12-tone music is based on
a scale (called a ‘note row’ or ‘basic
series’) that is devised especially for that
piece of music.
• The scale must contain 12 different notes
(notes of the chromatic scale), each note
to be used once only.

•
The notes are arranged in a chosen
order – ‘P’ (for ‘prime order’)

•
The note row is then written backwards
– ‘R’ (for ‘retrograde’)

‘P’ is then turned upside down - ‘I’ (for
‘inversion’).

• Each note of the row may be transposed
at the octave.
• Any of these four forms of the series may
be transposed (raised or lowered in pitch)
to begin on any of the 12 notes of the
chromatic scale – P1 to P11 (for ‘prime’).
• The row and its variants may be treated
melodically and harmonically (chords
built from the row).

COMPOSITION – INDIVIDUAL TASK
•
NGfL CYMRU GCaD
Select notes of the chromatic scale in
turn and write them down to form your
note row (P), thinking carefully about the
intervals between each note.
