Notation
SPN
MIDI is the note number synths and software pass around (0–127). Pitch class is the note without its octave — all the F♯s share one. Enharmonic spellings (F♯7 and G♭7) name the same pitch two ways.

Every row is F♯7 — only the A4 you tune to changes. A frequency scales straight with the reference: F♯7 at 432 Hz is the 440 Hz value times 432⁄440.
