Calculation method
Calculation method
Scale pitches including closing tonic
Repeat the supplied ordered within-octave intervals for each octave, then append the next octave tonic.
MIDI note numbers
Tonic MIDI number + octave × 12 + scale interval.
Degree positions
Degree indices restart at 1 each octave; the final closing tonic is degree 1.
Symbols and units
- a
- Starting tonic with octave
- b
- Ascending scale intervals from tonic (semitones)
- c
- Complete octaves plus closing tonic
- d
- Spelling: sharps or flats
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- A custom chromatic interval map, not an inferred musical mode. Uses scientific octave numbering and an explicit closing tonic. Spelling follows the selected chromatic sharp/flat list.
