Sitar: The sitar ( or ; Hindi: सितार Urdu: sitāra ) is a plucked stringed instrument used mainly in Hindustani music and Indian classical music.  The instrument is believed to have been derived from the veena, an ancient Indian instrument, which was modified by a Mughal court musician to conform with the tastes of his Mughal patrons and named after a Persian instrument called the setar (meaning "three strings").  The sitar flourished in the 16th and 17th centuries and arrived at its present form in 18th-century India.  It derives its distinctive timbre and resonance from sympathetic strings, bridge design, a long hollow neck and a gourd-shaped resonance chamber.  In appearance, the sitar is similar to the tanpura, except that it has frets.

Son huasteco: Son huasteco is one of 8 Mexican song styles and is a traditional Mexican musical style originating in the 6 state area of Northeastern Mexico called La Huasteca.  It dates back to the end of the 19th century and is influenced by Spanish and indigenous cultures.  Usually it is played by a "Trio Huasteco" composed of a guitarra quinta huapanguera (a five course, eight stringed guitar-like instrument) a Jarana huasteca (a stringed instrument related to the jarana) and a violin.  Singers will often use the falsetto register.  The son huasteco is particularly noteworthy for its flamboyant and virtuoso violin parts, although the style varies from state to state.  Footwork often danced to son huasteco is the Zapateado.  Improvisation plays a strong role in the style, with musicians creating their own lyrics and arrangements to a standard repertoire.  Typical "sones huastecos" are ""Cielito lindo"", ""La huazanga"", ""La sirena"", ""El querreque"" and ""La cigarra"".

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.
