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.)
The ondes Martenot (/ ˈ oʊ n d m ɑːr t ə ˈ n oʊ / OHND mar-tə-NOH; French: [ɔ̃d maʁtəno], "Martenot waves") or ondes musicales ("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 ...

Pitched musical instruments are often based on an acoustic resonator such as a string or a column of air, which oscillates at numerous modes simultaneously. As waves travel in both directions along the string or air column, they reinforce and cancel one another to form standing waves.
Vibration, standing waves in a string. The fundamental and the first 5 overtones in the harmonic series. A vibration in a string is a wave. Resonance causes a vibrating string to produce a sound with constant frequency, i.e. constant pitch. If the length or tension of the string is correctly adjusted, the sound produced is a musical tone.
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.
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 end of the string that mounts to the instrument's tuning mechanism (the part of the instrument that turns to tighten or loosen string tension) is usually plain. . Depending on the instrument, the string's other, fixed end may have either a plain, loop, or ball end (a short brass cylinder) that attaches the string at the end opposite the tuning m
