Equal Temperament Formula: The frequency of any note is calculated as f = A4 × 2^((n−69)/12), where n is the MIDI note number. This gives perfect octave doubling — every octave exactly doubles the ...

How Frequency is Calculated: Every semitone in 12-TET (12-Tone Equal Temperament) multiplies the frequency by the 12th root of 2 (≈ 1.05946). So if A4 = 440 Hz, then A#4 = 440 × 1.05946 = 466.16 Hz.
