String instrument String instrument String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when the performer plays or sounds the strings in some manner. Musicians play some string instruments by plucking the strings with their fingers or a plectrum—and others by hitting the strings with a light wooden hammer or by rubbing the strings with a bow. In some keyboard instruments, such as the harpsichord, the musician presses a key that plucks the string.

Vielle à roue et à manche Vielle à roue et à manche The vielle à roue et à manche (called dulcigurdy by some luthiers) is a modern term for an early music instrument, of unknown original name, of the hurdy-gurdy family, but distinct in that the notes were changed by fingering the neck rather than pressing tangent keys. The instrument has several strings which are constantly bowed by a spinning wheel turned by a crank, producing unbroken musical notes. The instrument is attested on Plate XXII of Praetorius' 1619 treatise Syntagma Musicum. The term "dulcigurdy" is a modern one, a portmanteau of "Appalachian dulcimer" and "hurdy-gurdy".
