The same note sits in several places
Unlike a piano, a guitar repeats the same pitch on different strings. Which one you take changes the tone and the shape your hand has to make.
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.

How to read this
- 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.
