Just Intonation guitars

Projections libérantes and L’école-atelier Lutherie-Guitare Bruand are joining forces for an unusual project: redesigning the positioning of the frets of a classical guitar.

The new positioning of the frets aims at obtaining natural pitches, that is to say pitches that are in proportions of whole number frequencies, rather than corresponding to the division of the octave into twelve equal parts, as prescribed by the conventional system.

Compared to conventional harmony, the consonances of natural harmony are softer, but its dissonances are also rougher. In other words, it is a territory for us to explore.
