Monochord

 

(1) An ancient Greek one-stringed instrument played by plucking.

(2) A device for determining the tone of a string and its parts. It consists of a string stretched between two bridges at the ends of an oblong wooden resonator; a movable bridge divides the string into two separately sounding parts. A scale of measurement is marked on the surface of the resonator. (Called also manichord, sonometer.)

(3) The una corda (in Russian, monokhord ); the device in a piano that enables the keyboard mechanism to shift to the side, allowing the hammer to strike not two or three strings of one chord simultaneously, but only one string. In the modern piano, the “soft” left pedal.

(4) Until the 18th century, the widely used term for the clavichord (Italian, monacordo, manicordo; French, manicorde, manichordion).

44) This manuscript, however, was copied after Aribo wrote his De musica, for it purports to transmit a set of monochord measurements `according to Aribo'.
Here she plays an instrument called the monochord which looks like a sitar the size of a small boat and is used to produce a drone sound.
Much like the paintings that imply an instrument or a performance, but do not actually depict one, Rossetti's sonnet "The Monochord" (LXXIX) (1870) uses the image of a monochord as a structural and symbolic construct, but does not actually refer to it outside of the title.
The temple, presided over by Apollo (the god of rational music) and Thalia (the joyous muse), contains within its structure representations of the various aspects of musical knowledge--a clock representing the durations of musical time, a monochord tower signifying the proper divisions, a lower vestibule showing Pythagoras and the smithy, graffiti on the walls presenting musical notation, two entryways representing the portals of the ears, and a spiral near the top signifying air set in motion by sound.
Village Life have released albums by Orquestra Mahatma & The Solid Strings, Martin Speake, a Clarvis trio with Stan Sulzmann and Tony Hymas and a Slany solo project called Monochord Music.
This group works by marked points within the twinned totals of 108 that represent -- but again proportionally -- perfect musical intervals seen either as "a group of poems, differentiated at each end by some structural mark (the ends of a sequence, say, or the ends of a series of poems in the same stanzaic pattern)" (71) along a monochord or, inversely, as harmonic divisions of the whole such as "an octave that could be divided by similar means into tetrachords, or tones, by counting equal divisions of the whole -- under this scheme, the fifth would occur seven-twelfths of the way through the group" (71).
There was now available to the West a practical method of notating music that was fully diastematic, whose intervals represented precise numerical ratios that could be converted directly into sound via the monochord.

In the Micrologus, the preferred method of memorizing intervals was through the use of the traditional monochord, but by the time Guido wrote his letter to Michael, he had developed a technique of reference syllables using the hymn Ut queant laxis.
To mention just one instance, Ptolemy used the monochord to mediate between reason (mathematical ratio, a Pythagorean criterion) and hearing (sense perception, a non-Pythagorean criterion), thus reconciling or balancing the two criteria; Boethius, on the other hand, used it to "legislate" or govern hearing, so that mathematical reason controls sense perception, a view more in line with Pythagorean t radition.
The second modal treatise, provided with a melody indicated by letter notation, treats several topics - common and indifferent modes and the monochord - not discussed in the first.
