Music without sound can refer to music that falls outside the range of human hearing or to compositions, such as visual music, that are analogous to or suggestive of conventional music but in media other than sound, such as color, shape, position, motion and literature. It is commonly taken for granted that music is wont to be performed or recorded, but some sound works simply won't fit on a disc or on stage, being either extremely discreet or incomplete. Additionally, silence can be regarded as the via negativa of music and has induced long lasting fascination to music composers of all kinds. A composer deals with the absence of sound as much as they deal with sounds. Therefore, this article includes several examples of apophasis in music.
Silence in music happens when the music stops during a performance. It is sometimes replaced by gesture music. In his Sofia Gubaidulina biography, Michael Kurtz mentions the silent solo performance by the conductor included in ...Stimmenn... verstummen..., an orchestral work from 1986. Milan Knizak
From 1960, the InternationalFluxus Movement created a number of Events or Verbal Pieces, whose temporal structures were typically vague so as to be sometimes without beginning nor end, with or without sound, with or without music. A remarkable example is that of Czech artist Milan Knizak's 1965 Snowstorm N°1 whose score states: Paper gliders are distributed to an idle and waiting audience.
Lachenmann composed Salut Für Caldwell for 2 guitars in 1977. The piece includes silent moments when « the players silent motions and gestures created a space of unheard music »
In 1963 Takehisa Kosugi composed for Fluxus 1 a musical piece called Theatre Music in the form of a rectangle of cardstock that bore the trace of a spiral of moving feet. This was paired with the instructions: "Keep walking intently".
Juan María Solare
His work Gestenstücke is a collection of five pieces for 4 performers in which a musical structure is used to put order in non-sounding elements, concretely gestures. For instance, the first piece of the cycle is a canon of gestures. Premiere: University Bremen, Ensemble Neues Musiktheater, June 12, 2008.
Another non-sounding piece is his conceptual work called Tense Atmosphere a graphic score which consists of a silence with a sforzato sign.
Algorithmic music
A sequence of finite instructions according to Wikipedia, an algorithm relates to computation, which ultimately relates to music. Eighteenth century algorithmic music is a contemporary of automaton machines, like Jacques de Vaucanson's duck or Wolfgang von Kempelen's chess player, or Ada Lovelace and Charles Babbage's 1822 difference engine. In 1787, W.A. Mozart devised an aleatoric system called Musikalisches Würfelspiel published 1793 by J.J. Hummel in Berlin-Amsterdam, to compose waltzes with a pair of dice and a set of written bars on paper cards. The combination of all the 16 cards and transitions, of which there are theoretically combinations, constitutes a minuet. Austrian composer Maximilian Johann Karl Dominik Stadler, also known as Maximilian Stadler, created a table to compose minuets and trios with a pair of dice. In the case of the minuet version, there are 16 cards with one bar each and preconceived transitions between certain musical measures. Mathematical games columnist Martin Gardner once remarked in an article about automated music composition. "If you fail to preserve it, it will be a waltz that will probably never be heard again." The method of pure aleatoric music was used in the twentieth century by US composer Lejaren Hiller.
started building his optophonic piano in the 1915s. A set of painted glass discs are rotated via the small keyboard. Light is projected through the discs onto the wall. The player can control intensity of light and speed of rotation. 6 or 8 keys of the 3-octaves keyboard are devoted to colored discs. It is not clear what kind of sound the keyboard is able to produce. Oscillator frequencies are rather unlikely between 1915-1920. More probably the light show was performed with piano accompaniment, maybe performed on the reduced keyboard of the Optosonic Piano, akin to a toy piano.
Unfinished/aborted music
At one point, the music exists in the composer's mind. In 1928, Edgar Varèse started working on an opera called L'Astronome based on North American Indian legends, a project he never completed and destroyed the drafts. In 1932, he asked Antonin Artaud to write the libretto of a large scale oratorio, Il n'ya plus de firmament. In his book Phantasmatic RadioAllen S. Weiss translates the beginning of Artaud's text: The piece was never completed and Varèse turned to other projects, including a radiophonic work involving various synchronised choirs located in different places of the world. He never found the technology for it. In 1948, Artaud insisted on having noise sounds included in his Pour en finir avec le judgement de Dieu. This was done in the Radiodiffusion Television Française studios where Pierre Schaeffer was working at the time.
Silent music
Silent Music is an installation work by Canadian artist Robin Minard with several hundred wall-mounted piezo loudspeakers and four-channel audio. The miniature loudspeakers are displayed in plant-like shapes on the walls of public spaces. They reproduce the minuscule ambient sounds of the public space where they are installed or play random synthetic sounds at barely audible volume. Minard deals with remote sounds best suited to intimate listening. In 2006 he created 'A voir en silence', a small artist book with loudspeakers and hand-written text.
The Vinteuil Sonata is an imaginary violin and piano sonata by fictitious composer Vinteuil recurring several times in Marcel Proust's A La Recherche Du Temps Perdu, particularly in Un Amour De Swann. In the latter volume, Charles Swann associates strong emotions and memories to the melody composed by Vinteuil. The French composer Reynaldo Hahn noticed how much Marcel Proust "vivait la musique de son temps". For example, Proust immediately praised and enjoyed Debussy's 1902 Pelléas et Mélisande opera. Critics disagree on which composer inspired the Sonata. Possibly Gabriel Fauré or César Franck. In :fr:Les Plaisirs et les Jours|Les Plaisirs et les Jours, Proust focusses on Hans Sachs's monologue from Wagner's Die Meistersinger von Nürnberg, Act II. In Jean Santeuil, a Camille Saint-SaënsSonata for Violin and Piano plays a key role and is presumably the model for the Sonate de Vinteuil. In Un Amour De Swann, the Vinteuil Sonata is played during evenings at the Verdurins' by pianist Dechambre. The main character's emotions are mirrored by Proust's musical reminiscences. Walter Marchetti
A good example of imaginary music can be found in a Walter Marchetti poem where he mentions a Juan Hidalgo imaginary composition.
