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 ." A "bichord instrument" is one, "having two strings in unison for each note [a ]," such as the . With two strings one can easily demonstrate how various musical  sound. Both open strings are tuned to the same pitch, and then the movable bridge is put in a mathematical position on the second string to demonstrate, for instance, the  (at 4/5th of the string length)   (·) or the  (at 5/6th of the string length)   (·).
