What we call a monochord today was originally an instrument with one string, which was used at the time of Pythagoras as a measuring instrument. It was discovered  that shortening the freely vibrating string using integral subdivisions ( a half, a third, a quarter etc.) produced a harmonic sequence of notes which corresponds to the natural overtone scale: octave, fifth, fourth, third…

This discovery was applied to other fields such as architecture. So for example the dimensions of a door commonly built today are 2m x 1m, which corresponds to the interval of an octave.

The Meerklang monochords are strung with 30 to 36 strings which are all tuned to the same note, with the 2 outer strings a little thicker so that they produce a note an octave lower.

This means that the instrument not only has rich overtones and sounds from higher spheres, but also a beautiful warm bass.  In order to strengthen this effect we can add a third bass string in the middle.

So the monochord by comparison with the kotamo is limited to only one single tone, but on account of the many strings it opens up the whole overtone spectrum in the same fascinating way. You cannot however play a melody on it, like on the koto.

The playing technique is extremely simple  and so the monochord is suited to anyone who wants to play with sounds in a meditative way.


The standard monochord is available in 6 different sizes



Measurements and types:

If you wish we can make the instrument to other measurements.

It is also possible to order a monochord with an outwardly curved belly, which creates a fuller sound.
