It uses several friction wheels instead of a friction belt to vibrate the strings, and requires two people to play it: one to turn the crank to put the rosined wheels in motion, and the other to work the keys. [2] Georg Gandi, an organist in Ilmenau, constructed a similar instrument with some improvements in 1709 and called it the piano viol.
The thereminist stands in front of the instrument and moves their hands in the proximity of two metal antennas. While commonly called antennas, they are not used as radio antennae for receiving or broadcasting radio waves, but rather act as plates of capacitors. The distance from one antenna determines frequency (pitch), and the distance from ...
Playing a harmonic on a string. Here, "+7" indicates that the string is held down at the position for raising the pitch by 7 half notes, that is, at the seventh fret for a fretted instrument. String instruments can also produce multiphonic tones when strings are divided in two pieces or the sound is somehow distorted.
On bowed instruments, the need to play strings individually with the bow also limits the number of strings to about six or seven; with more strings, it would be impossible to select individual strings to bow. (Bowed strings can also play two bowed notes on two different strings at the same time, a technique called a double stop.)

On a stringed instrument, a note played by stretching a string away from the frame of the instrument and letting it go, making it "snap" against the frame. Also known as a Bartók pizzicato. Natural harmonic or Open note On a stringed instrument, this means to play a natural harmonic (also called flageolet). Sometimes, it also denotes that the ...
Playing a harmonic on a string. Here, "+7" indicates that the string is held down at the position for raising the pitch by 7 semitones. Playing a string harmonic (a flageolet) is a string instrument technique that uses the nodes of natural harmonics of a musical string to isolate overtones. Playing string harmonics produces high pitched tones ...
' Martenot waves ') or ondes musicales (lit. ' musical waves ') is an early electronic musical instrument. It is played with a keyboard or by moving a ring along a wire, creating "wavering" sounds similar to a theremin. A player of the ondes Martenot is called an ondist. The ondes Martenot was invented in 1928 by the French inventor Maurice ...
