Hurdy-gurdy Hurdy-gurdy The hurdy-gurdy is a stringed instrument that produces sound by a hand crank-turned, rosined wheel rubbing against the strings. The wheel functions much like a violin bow, and single notes played on the instrument sound similar to those of a violin. Melodies are played on a keyboard that presses "tangents"—small wedges, typically made of wood—against one or more of the strings to change their pitch. Like most other acoustic stringed instruments, it has a sound board and hollow cavity to make the vibration of the strings audible. Most hurdy-gurdies have multiple drone strings, which give a constant pitch accompaniment
Experimental musical instrument the "Bowafridgeaphone" (bow a fridge a phone). Leila Bela is an Iranian-born American avant-garde musician and record producer from Austin, Texas. The Japanese multi-instrumentalist and experimental musical instrument builder Yuichi Onoue developed a two string hurdy-gurdy like a fretless violin, called the Kaisatsuko, as well as a deeply scalloped electric guitar for microtonal playing techniques. Solmania from Japan, and Neptune are noise music bands that built their own custom made guitars and basses. Solmania modifies their instruments with extra droning strings. Neptune built guitars out of scrap metal and make electric lamellophones. The bass is built using a VCR casing
