Violin where a stopped note sounds a unison or octave with another (open) string, causing it to resonate sympathetically. Students often use these ringing tones to check the intonation of the stopped note by seeing if it is harmonious with the open string. For example, when playing the stopped pitch "A" on the G string, the violinist could play the open D string at the same time, to check the intonation of the stopped "A". If the "A" is in tune, the "A" and the open D string should produce a harmonious perfect fourth. Violins are tuned in perfect fifths, like
Basic physics of the violin bridge and nut of the violin so that the ends are essentially stationary, allowing for the creation of standing waves. The fundamental frequency and harmonic overtones of the resulting sound depend on the material properties of the string, such as the tension, length, mass, elasticity and damping factor. String tension affects the sound a violin produces in an obvious way. Increasing the tension on a string results in a higher frequency note. The strings of a violin are wrapped around adjustable tuning pegs. By turning its associated peg, each string may be loosened or tightened until it produces the desired
