Harmony Interval
Build a harmony voice above and below a note using a chosen interval.
About Harmony Interval
A harmony voice sits a chosen musical interval above or below the lead, each derived from the same frequency ratio. Arranging vocals or instruments in thirds, fifths and octaves is the foundation of richer, fuller mixes.
Formula
Harmony Interval
Harmony = lead x 2^(interval/12) above, and the inverse below
- interval
- The named harmonic distance from the lead voice
Worked example
With the default values below, Harmony Interval returns Harmony Above of 554.37. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
