Δεν έχω ιδέα. H Wikipedia λέει:
"On guitars, there are two popular fretboard inlays schemes:
* The most popular one (1) involves single inlays on the 3rd, 5th, 7th, 9th, double inlays on the 12th, single inlays on the 15th, 17th, 19th, and 21st, and if present, double inlays on the 24th. Pros of such scheme include its symmetry about the 12th fret and symmetry of every half (0-12 and 12-24) about the 7th and 19th frets. However, playing these frets, for example, on E string would yield notes E, G, A, B, C#
that barely make a complete musical mode by themselves.

Αλλά στις κιθάρες που έχουν το πιο ασυνήθιστο 3,5,7,
10,12... αν παίξεις από την ανοιχτή π.χ. Μι πάνω στα τάστα με τα inlays παίζεις
πεντατονική (μι σολ λα σι ρε μι...):
"* A less popular one (2) involves inlays on 3rd, 5th, 7th, 10th, 12th, 15th, 17th, 19th, 22nd and 24th frets. Playing these frets, for example, on E string yields notes E, G, A, B, D that fit perfectly into E minor pentatonic. Such a scheme is very close to piano keys coloring (which involves black coloring for sharps that pentatonic consists of) and of some use on classical guitars".
