music.interval-ratio Calculator
Computes the frequency ratios for musical intervals in both equal temperament and just intonation, and shows the difference in cents between them. Just intonation intervals are acoustically 'pure' (simple integer ratios) but require different tuning for every key — the compromise that led to equal temperament.
Inputs
Root
Cycles per second (Hz). Audible sound: 20 Hz – 20 kHz. Make sure units match what the formula expects.
Semis
Reference formula or conversion factor shown for context.
Tuning
Reference formula or conversion factor shown for context.
Results
equal temperament (Hz)
Sample size or count used in the calculation.
just intonation (Hz)
The value at the specified point or condition.
interval ratio
The proportional relationship between two quantities.
