Frequency comparison tool

Answer

Compare any two pitches by hertz difference, ratio, and cents (1200 × log2(a/b)). Useful for carriers, solfeggio pairs, or tuning questions.

Explain

cents = 1200 · log2(fa / fb)

100 cents = 1 semitone in equal temperament. This tool is educational math — not a claim about healing intervals.
