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

From note

Starting note, e.g. C4.

To note

Target note, e.g. E4.

Return the signed semitone distance between two scientific-pitch notes such as C4 and E4. 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]

Semitones

Semitones from the starting note to the target note.

• 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.

• Cents Between Two Frequencies

  Signed interval in cents from a positive reference frequency to a positive target frequency.

• Melodic Range Span Semitones

  Melodic span in semitones between lower and upper MIDI notes.

• 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.
