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 double-dotted note: seven quarters of 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]

Double Dotted Seconds (s)

The resulting double 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.

• Dotted Note Duration Calculator

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

• Frequency From MIDI Calculator

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

• Grace Note Duration Subtraction

  Remaining duration of a main note when a grace note borrows a specified number of seconds from it.
