Tritare
A tritare is an experimental guitar invented in 2003 by mathematicians Samuel Gaudet and Claude Gauthier of the Université de Moncton of a family of stringed instruments which use Y-shaped strings, instead of the usual linear strings. == Instrument sound and reactions == Y-shaped strings can produce sounds which are harmonic integer multiples, but also non-harmonic sounds more akin to those produced by percussion instruments.
