Y-STRING GUITAR

Each string on this guitar-like instrument forks into two strings just before entering the bridge. This irregularity makes the string slightly less rigid for one direction of vibration as compared to the other. That complicates the sound by creating a slight dual-pitch effect. It also adds a bit of weight at the forking point, making the string’s weight distribution uneven. This further complicates the sound by making the overtones inharmonic.
