Enter your pitch classes, operation, and value into the calculator to determine the resulting pitch class set.

Pitch Class Set Calculation Formula

The following formula is used to calculate the pitch class set.

Resulting Pitch Class Set = (Pitch Class Set + Value) % 12

Variables:

  • Pitch Class Set is the set of pitch classes (integers from 0 to 11)
  • Value is the transposition interval
  • Resulting Pitch Class Set is the transposed or inverted set of pitch classes

To calculate the resulting pitch class set, add the value to each pitch class and take modulo 12.

What is Pitch Class Set Calculation?

Pitch class set calculation refers to the process of determining the resulting set of pitch classes after applying operations like trans
