Use this music calculation for a precise timing, pitch, tuning, MIDI, dynamics, or audio-engineering conversion under a stated tempo and reference convention.

Pitch Class

Required number input.

Clockwise circle-of-fifths position 0–11 from a chromatic pitch class (C=0, C-sharp=1, ... B=11). The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Clockwise Position

The resulting clockwise position returned as a number.

• Results depend on tuning reference, temperament, note naming, tempo map, meter, MIDI implementation, sample rate, level reference, weighting, and artistic performance. Equal temperament and ideal timing are not universal musical requirements.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Keep the reference pitch and timing grid explicit, verify against the target instrument or DAW, and use listening tests for perceptual decisions.

• Just Intonation Ratio To Cents

  Pitch interval in cents for a positive just-intonation frequency ratio numerator/denominator.

• Pitch Bend Semitone Range 14bit

  Signed semitone offset from a 14-bit MIDI pitch-bend value using center 8192 and a specified full-scale range.

• Scientific Pitch Notation Octave

  Scientific-pitch octave number for a MIDI note, where MIDI 60 is C4.
