Description

The monochord is the instrument that Pythagoras and other theorists used to study the relationships between string length and pitch, and between pitches themselves. It is still used today as a teaching tool. It consists of an elongated sound box with a number of strings stretched across it. There are often two strings, tuned in unison with tuning pegs, and a third string whose tension is controlled by a pulley with weights.

Pythagoras investigated the relationship between string length and pitch and noticed that dividing the string produced more harmonious sounds as the numbers of the ratio became smaller: 1:2 produces an octave, 2:3 a fifth, 3:4 a fourth, 4:5 a major third, 5:6 a minor third, 8:9 a whole tone. Conversely, the ratios of the string lengths reflect the frequency ratios of the tones. The degree of harmony is called consonance, while disharmony is called dissonance.
