The frets crowd as you climb
Frets are spaced by ratio, not by equal steps: each one divides the remaining length by the twelfth root of two. That is why the 12th fret lands at exactly half the string — the octave.

- One fret is one semitone; twelve of them make an octave.
- Frequency multiplies by the twelfth root of two per semitone — A4 is 440 Hz.
- Fret position = scale length × (1 − 1 ÷ 2^(fret/12)).
- String 1 is the thinnest; standard tuning reads E-B-G-D-A-E from there.
