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

Undotted Seconds (s)

Required number input.

Duration of a single-dotted note: one and a half times its undotted duration. 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]

Dotted Seconds (s)

The resulting dotted seconds 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.

• Double Dotted Duration Calculator

  Duration of a double-dotted note: seven quarters of its undotted duration.

• Tuplet Ratio Duration Calculator

  Duration of one tuplet note: a normal note duration times the number of normal notes in the span divided by tuplet note count.

• Frequency From MIDI Calculator

  Convert a MIDI note number to its equal-tempered frequency with A4 = 440 Hz.
