Works for prepared piano by John Cage
started composing pieces for solo prepared piano around 1938-40. The majority of early works for this instrument were created to accompany dances by Cage's various collaborators, most frequently Merce Cunningham. In response to frequent criticisms of prepared piano, Cage cited numerous predecessors. In the liner notes for the very first recording of his most highly acclaimed work for prepared piano, Sonatas and Interludes, Cage wrote: "Composing for the prepared piano is not a criticism of the instrument. I'm only being practical." This article presents a complete list of Cage's works for prepared piano, with comments on each composition. All of Cage's indeterminate works for unspecified forces can also be performed on or with Prepared Piano.
Solo
Bacchanale
In interviews conducted in 1974 and 1982, Cage specified that this piece was composed in 1938. However, the manuscript used for Edition Peters' edition of Bacchanale specified 1940 as the date, and this has been used by numerous scholars since. The circumstances of the piece's composition are much more clear: it was created for a choreography by the American dancer Syvilla Fort. Cage and Fort were both working at the Cornish School in Seattle, Washington at the time. The room where the dance was to be performed was not large enough to allow for a percussion ensemble, but had enough space for a grand piano. Cage decided to try placing various objects on the strings of the instrument in order to produce percussive sounds, inspired by Henry Cowell's experiments with extended piano techniques. In 1982 Cage mentioned that the whole piece was completed in just three days. Twelve notes are prepared, mostly using weather strippings. In the score, in 11 cases out of 12, the performer is instructed to "determine position and size of mutes by experiment."Totem Ancestor
Composed in 1942 for a dance by Merce Cunningham. Eleven notes are prepared, eight of them by screws. This is the only Cage-Cunningham collaboration from the 1940s for which original choreography has survived.And the Earth Shall Bear Again
Composed in 1942 for a dance by Valerie Bettis. Ten individual notes are prepared, mostly with small screws, and a whole range from G1 to C3 is prepared using "two thicknesses of woolen material". This material is placed between the strings in the following manner: over the first string, under the second, over the third, under the fourth, etc.Primitive
Composed in 1942 for a dance by Wilson Williams. Thirteen notes are prepared, all using screws or bolts.In the Name of the Holocaust
Composed in late 1942 for a dance by Merce Cunningham. The title references World War II. Piano preparation involves only screws or bolts. Various extended techniques are used, such as producing sound by plucking strings. The piece starts with quiet, muted tones and gradually becomes louder, climaxing in several successions of large tone clusters, executed using the entire length of the forearm.Our Spring Will Come
Composed in 1943 for a dance by Pearl Primus. Piano preparation involves bamboo strips, as well as screws and nuts. The music and the dance were to be accompanied by a speaker reading a poem by Langston Hughes about the condition of Black people in the United States.A Room
Composed in 1943, originally conceived as the third part of She Is Asleep. May be performed with or without preparations, which involve 11 notes. Most are to be prepared using bolts, one new material is a penny. The music is written down on a single staff and follows the structure 4, 7, 2, 5, 4, 7, 2, 3, 5, repeated twice.Tossed As It Is Untroubled
Composed in 1944 for a dance by Merce Cunningham, and dedicated to Valerie Bettis. Originally titled Meditation. Only eight notes are prepared, mostly with weather strippings. Roughly two thirds of the piece are written down on a single staff; the melodic line which makes up most of the piece uses just five tones, all prepared with weather strippings. The two heavily prepared notes are only used for a trill at the very end of the work.A Valentine Out of Season
A suite of three pieces, composed in 1944. Choreographed by Merce Cunningham as Effusions avant l'heure / Games / Trio. The title references Cage's separation from his wife Xenia, which happened in 1945.Prelude for Meditation
Composed in 1944. A very short work that only uses four tones.Root of an Unfocus
Composed in 1944 for a dance by Merce Cunningham. A work in three sections: Section 1 contains seven parts, seven bars each; Section 2 juxtaposes bars in 4/4 and 3/4 metres; Section 3 divides 100 half notes into three groups of 23 and a coda. According to Cunningham, the subject of the work is fear: it describes "awareness of the unknown, struggle, and the final defeat".Spontaneous Earth
Composed in 1944 for a dance by Merce Cunningham.The Unavailable Memory of
Composed in 1944 for a dance by Merce Cunningham. Written entirely on a single staff, primarily scored as a single melodic line.Triple-Paced No. 2
This work, composed in 1944, is a revision of a 1943 piano piece titled Triple-Paced. The 1944 version was choreographed by Merce Cunningham.The Perilous Night
Composed in 1944. This is Cage's first large-scale work for prepared piano. Twenty-six notes are prepared with various materials. The piece contains six separate sections with different rhythmic structures. According to Cage, The Perilous Night expresses "the loneliness and terror that comes to one when love becomes unhappy". All of the six movements of this work are untitled. 38 years after its composition, his longtime friend artist Jasper Johns included a silkscreen of the score in a large mixed-media diptych which itself is also titled “Perilous Night.”Mysterious Adventure
Composed in 1945 for a dance by Merce Cunningham. This is another large-scale work with moderately complex piano preparation, involving 27 notes. It contains five sections.Daughters of the Lonesome Isle
Composed in 1945 for a dance by Jean Erdman. Contains nineteen sections. Thirty-nine notes are prepared.Music for Marcel Duchamp
Composed in 1947 for a segment of Hans Richter's surrealist film Dreams That Money Can Buy. The film contains several segments designed by different artists, and Cage's music was composed for a segment designed by Marcel Duchamp. The segment—a dream one of the characters is having—is titled "Discs" and consists mostly of Duchamp's rotoreliefs. These are designs painted on flat cardboard circles, which are to be spun on a phonographic turntable. The work was later choreographed by Merce Cunningham. The global structure is 11x11, the rhythmic proportion is 2, 1, 1, 3, 1, 2, 1. Similarly to Tossed As It Is Untroubled and The Unavailable Memory of, the work mostly builds on a single melodic line, which uses notes muted by weather strippings. This piece is one of the first to explore the idea of silence systematically: empty bars are juxtaposed with melodic passages throughout the piece.Sonatas and Interludes
A cycle of 20 short works composed in 1946–48. Dedicated to pianist Maro Ajemian. This is Cage's most famous work for prepared piano, and also the most complex: piano preparation takes about 2–3 hours and involves forty-five notes, and the proportions governing the structure of individual pieces include fractions as well as natural numbers. Sonatas and Interludes was inspired by Cage's interest in Indian philosophy and the Rasa aesthetic as explained in Ananda K. Coomaraswamy's writings. The pieces express the eight "permanent" emotions and their common tendency toward tranquility.Music for ''Works of Calder''
Composed in 1950 for Herbert Matter's short film on sculptor Alexander Calder, Works of Calder. The idea of the film was suggested by Burgess Meredith, whom Calder met in spring 1948. The decision to ask Matter to direct was Calder's: the two had worked with each other previously when Matter made photographs of Calder's works. The 20-minute color film, produced and narrated by Meredith and photographed and directed by Matter, was completed in 1949, but since Matter insisted on asking Cage to compose the music, the team had to wait for about a year until Cage returned from Europe. The piece consists of three sequences, two of which are for prepared piano, and one is for tape: Cage recorded the sounds of Calder's studio while the sculptor was working —mobiles bumping into one another, etc.—then edited the resulting two-hour recording in order to produce the desired sequence of sounds.Two Pastorales
Composed in November 1951 and January 1952. Both pastorales use chance operations applied using charts of layers, sounds, durations, etc. and the I Ching, similarly to Music of Changes. Because the number of layers was smaller than in the latter work, the texture of Two Pastorales is thinner, with long silences between notes. Like in Music of Changes, the notation is proportional, one inch equals one quarter note. Extended techniques are used: strings are sometimes plucked by fingers or cymbal sticks, or muted by hand.34'46.776" For a Pianist
Composed in 1954, this work is one of the so-called "time length" pieces, in which the title refers to the length of the work. The piece was composed using chance operations and written down in proportional graphic notation. The rhythmic structure is 3, 7, 2, 5, 11. Piano preparation is defined only by specifying the strings to be prepared and the materials to be used, the actual choice of objects and their position on the strings is left to the performer. This piece was composed for David Tudor and is very difficult to play; its companion piece, 31'57.9864" For a Pianist, shares the same techniques but is much easier. Both works may be performed solo or together with other "time length" compositions.31'57.9864" For a Pianist
Composed in 1954. A companion piece to 34'46.776" For a Pianist, it uses similar notation and compositional techniques, but is much easier to play. The rhythmic structure is also identical to 34'46.776".Two prepared pianos
A Book of Music
Composed in 1944. Like the later work, Three Dances, A Book of Music was commissioned by pianists Robert Fizdale and Arthur Gold. It was Cage's first work written on request from professional performers. There are two movements, each divided into several smaller sections. The music makes much use of scales and arpeggios and features much virtuosic writing. According to Cage, this was inspired by his ideas on Mozart's music, which "strictly adheres to three different kinds of scales: the chromatic, the diatonic, and that consisting of the larger steps of thirds and fourths". The technique of rhythmic proportions is used in a new way: the proportion for each piece is defined for a particular tempo. A change in the tempo causes a change in the proportion.Three Dances
Composed in 1945. This work is similar in style and technique to A Book of Music and too was commissioned by Fitzdale and Gold.Ensemble
Second Construction
Composed in 1939–40. This piece is scored for various percussion instruments and piano. The score instructs the performer to insert a screw and a strip of cardboard between several strings, but the piano part is written essentially for the string piano technique. The rhythmic proportions — 16 groups of 16 bars divided 4, 3, 4, 5 — are defined in the score, but the music doesn't always rely on them.She Is Asleep
An unfinished suite of different pieces, composed in 1943. The two completed movements are:- Quartet for 12 tom-toms
- Duet for voice and prepared piano
Amores
Composed in early 1943 after Cage moved to New York City, as a concert piece. Choreographed by Merce Cunningham in 1949. Amores contains four movements:- Solo for prepared piano
- Trio for 9 tom-toms and a pod rattle
- Trio for 7 wood blocks
- Solo for prepared piano
Four Dances
Composed in 1943–44 for a choreography by Hanya Holm. Original title What So Proudly We Hail, also known as Suite of four dances. The four dances are:- Dance No. 1 for percussion and piano
- Dance No. 2 for tenor soloist and piano
- Dance No. 3 for piano
- Dance No. 4 for tenor soloist, percussion and piano
