Just Intonation Guitars

This Just Intonation guitar project is the brainchild of composer Simon Martin, in collaboration with luthier René Wilhelmy and L’école-atelier Lutherie-Guitare Bruand. Its aim is to redesign the positioning of a guitar’s frets to obtain pitches that differ from the conventional system. An almost infinite variety of systems can be explored, from historical temperaments to extra-Western modes and, in this case, natural harmony.

The instruments and keys we have made are available to the public. We look forward to hearing from you!

Learn more about the history of the project, as well as two sketches composed for our first Just Intonation protoype guitar.

Explore all the fingerboard models we haveve designed, and the theoretical framework in which they are based.
