The monochord can be used to illustrate the properties of musical and to illustrate regarding string length and tension: "essentially a tool for measuring musical intervals". For example, when a monochord's string is open it vibrates at a particular frequency and produces a pitch. When the length of the string is halved, and , it produces a pitch an higher and the string vibrates at twice the frequency of the original (2:1) (·). Half of this length will produce a pitch two octaves higher than the original—four times the initial frequency (4:1)—and so on. Standard diatonic (Ptolemy's Diatonic Ditonic) is easily derived starting from ratios, (n+1)/n, constructed from the first four counting numbers, the , measured out on a monochord.[] The mathematics involved include the , , and and .Several string "monochord""As the name implies, only one string is needed to do the experiments; but, since ancient times, several strings where used, all tuned in exact unison, each with a moveable bridge, so that various intervals can be compared to each other ."
