Pitch Transposition Scalings




Below is a table of pitch transpositions by half-step in equal temperament. To transpose a pitch up by a perfect fifth search for +7 in the left-hand columns in the table below, then see what multiplier is necessary to raise the pitch of a frequency by a perfect fifth. In this case the multiplier is 1.49831 (slightly flat from a just-intonation perfect-fifth).

The table covers transpositions between +4 and -4 octaves from the original pitch.
