Number Pieces

Add article description

The term Number Pieces refers to a body of late compositions (40, or 41 if Seventeen was actually composed) by John Cage. Each piece is named after the number of performers involved: for instance, Seven is a piece for seven performers, One⁹ (read "One Nine") is the ninth work for one performer, and 101 is a piece for an orchestra of 101 musicians. The vast majority of these works were composed using Cage's time bracket technique: the score consists of short fragments (frequently just one note, with or without dynamics) and indications, in minutes and seconds, during which the fragment can start and by what time it should end. Time brackets can be fixed (e.g. from 1.15 to 2.00) or flexible (e.g. from anywhere between 1.15 and 1.45, and to anywhere between 2.00 and 2.30).

Two time brackets from Five (1988), the first one flexible, the second fixed

All of the Number Pieces were composed during the last six years of Cage's life, 1987–1992. Most are for traditional instruments, with six exceptions that range from works for rainsticks, the Japanese aerophone shō and conch shells to an electronically amplified version of 4′33″. This article lists all Number Pieces, organized by number of performers.

Title	Instrumentation	Date of composition	Dedicatee(s)	Details
One	piano	December 1987	Juan Allende-Blin	10 time brackets, all flexible except for the ninth. Each contains music written on two staves, but the content of one staff can be played in any relation with that of the other staff.
One²	1–4 pianos	Summer 1989	Margaret Leng Tan	The pianist moves between several pianos (in 1992 Cage advised Margaret Leng Tan to use the I Ching to coordinate her movements). All instruments have their damper pedals wedged, so that the strings vibrate freely throughout the piece.
One³	unspecified (amplified ambient sound)	late 1989		Full title: One³ = 4′33″ (0′00″) + . There are no time brackets. The performer is to arrange a sound system so that "the whole hall is on the edge of feedback, without actually feeding back." Thus the composition consists entirely of electronically amplified sound of the hall and the audience.
One⁴	percussion	1990	Fritz Hauser	6 time brackets for the left hand and 8 for the right. Each contains a numeral on a stave, referring to an instrument — the piece is to be performed on "cymbals and/or drums chosen by the drummer." Cage adds that the sounds produced should be either very long or very short.
One⁵	piano	May 1990	Ellsworth Snyder	21 time brackets for the left hand and 24 for the right. Each contains a single chord or a single note. The performer is instructed to either hold the pedal throughout, or make as many overlappings as possible (again, using the pedal if necessary).
One⁶	violin	June 1990	János Négyesy	The time brackets are extremely long in this piece, up to 7 minutes, many overlap, and all contain just a single tone. Performances of the piece can be accompanied by a sound sculpture by Mineko Grimmer, which is made of ice with pebbles in it. When the ice melts, the pebbles fall and strike wires, producing sound, and then fall into a pool of water. One⁶ was initially intended for Paul Zukofsky.
One⁷	unspecified	Fall 1990	Pauline Oliveros	This piece is the first part from Four⁶. The performer chooses 12 different sounds and plays within flexible time brackets.
One⁸	cello with curved bow	April 1991	Michael Bach	There are 53 time brackets, each with a single sound produced on one, two, three or four strings. This Number Piece is microtonal. It may be performed with 108.
One⁹	shō	July 1991	Mayumi Miyata	Ten movements, amounting to maximum total duration of 121 minutes. Any three movements of this piece may be performed with 108.
One¹⁰	violin	February 1992		Each time bracket contains a single sound. Like One⁶, this piece can be performed simultaneously with a sound sculpture by Mineko Grimmer; the sculpture is essentially the same as in the earlier piece, but in a different configuration.
One¹¹	unspecified (film)	1992		This Number Piece is a film that consists of chance-determined play of electric light. It is scored for "solo cameraman." It may be performed with 103.
One¹²	voice	1992	Alfonso Fratteggiani Bianchi and the Quaderni Perugini di Musica Contemporanea	Possibly not a separate work, but a performing score for One⁷. The score contains instructions for creating a chance-determined series of 640 numbers between 1 and 12. The numbers are then interpreted as vowels or consonants (numbers 2–11), words (12) or "empty words" (1; pronouns, articles, etc.). The choice of words is left to the performer.
One¹³	cello with curved bow 1 live and 3 recorded cellos	July–August 1992	co-author is Michael Bach Bachtischa^[1]	The work remained incomplete at the time of John Cage's death but was published in 2009 as a collaborative composition with Michael Bach Bachtischa. The work has four voices, all playing the same note, but with various differences.

Two	flute and piano	December 1987	Roberto Fabbriciani and Carlo Neri	This was the first Number Piece. Both parts contain 9 flexible time brackets and one fixed. Originally devised for flute and vibraphone,^[2] the flute part has only three different pitches and is quiet throughout, dynamics ranging from mp to pp. The piano part is notated on two staves, with the content of one played in any relation to that of the other. Each piano time bracket consists of 7 to 10 sounds.
Two²	2 pianos	Summer 1989	For "Double Edge": Edmund Niemann and Nurit Tilles	This piece does not use time brackets. The score consists of 36 lines of music, 5 bars each. There are 31 sound events per each line, divided 5, 7, 5; 7, 7 as in Renga poetry. The pianists play one bar at a time in different tempi, both have to finish playing the bar at hand before moving to the next one.
Two³	shō and five conch shells	July 1991		The shō part is the solo shō Number Piece, One⁹. There are 10 movements in this work, amounting to 121 minutes total duration. The conch shell parts contain only fixed time brackets. Within each time bracket there are two numbers: the first refers to the conch, the second, in superscript, refers to the intended number of bubbles to be produced (the shells are filled with water and "played" by carefully tipping them until a bubble forms inside, producing a sound). Any three movements of this piece may be performed with 108.
Two⁴	violin and piano or shō	July 1991	Commissioned by the McKim Fund of the Library of Congress	Only flexible time brackets are used. The violin part is microtonal and consists for the most part of long sounds. It is divided into three movements. The piano/shō part contains mostly short sounds and is in four movements.
Two⁵	tenor trombone and piano	October 1991	Hildegard Kleeb and Roland Dahinden	The trombone part is microtonal. Both parts include silences (up to 5 minutes).
Two⁶	violin and piano	April 1992	Ami Flammer and Martine Joste	The time brackets of Two⁶ are empty and the performers have to fill them themselves. The pianist's material consists of parts of Extended Lullaby (chance-determined variations of Erik Satie's Vexations) and sequences of ascending pitches. The violinist chooses between silence, microtonal passages, or dyads from chance-determined pitches.

Four

Four	string quartet	1989, before May 9	Arditti Quartet	There are three five-minute sections: A, B, and C. All parts contain 10 time brackets, 9 flexible and one fixed. The structure of the piece varies depending on how long the desired duration is. For a 10-minute performance, section B is played once, then the performers exchange their parts according to the instructions in the score, and then section B is played again. For a 20-minute performance, only sections A and C are played, without pause, but again with the performers exchanging parts between sections. Finally, a complete 30-minute performance requires the sections played in the ABC order twice. Time brackets contain only single tones at low dynamics (p to ppp).
Four²	SATB chorus	October 1990	Madrigal Choir of the Hood River Valley High School	There are 3 time brackets for sopranos, 4 for altos, 6 for tenors, and 6 for the basses. The score also supplies a pronunciation table. Each section of the chorus (sopranos, altos, etc.) may be divided into two or more groups, so that one group started the sound and the other continued it.
Four³	1–2 pianos, violin or oscillator, 12 rainsticks (three for each performer)	May 1991	Merce Cunningham Dance Company	There are 24 empty flexible time brackets, to be filled by the performers. The piano part is to be constructed from Extended Lullaby, 48 chance-determined variations on Erik Satie's Vexations. Each of these consists of 12 eighth notes. Sounds other than the piano are silence, a high frequency sine wave played on an oscillator or on a violin (without vibrato), and the sound of rainsticks (played by tilting them).
Four⁴	percussion	October 1991	Amadinda Percussion Group	The four performers have 22, 16, 10 and 15 time brackets respectively. Instruments are chosen by the performers; the time brackets only contain numerals to refer to different instruments.
Four⁵	four saxophones	October 1991	John Sampen
Four⁶	unspecified	March 1992	Pauline Oliveros, Joan La Barbara, William Winant and Leonard Stein	Each performer chooses 12 different sounds and plays within flexible time brackets. The sounds must have fixed amplitude, overtone structure, etc. The first performer's part may be performed solo, as One⁷.
