Piano Phase

Last updated

Piano Phase is a minimalist composition by American composer Steve Reich, written in 1967 for two pianos (or piano and tape). It is one of his first attempts at applying his "phasing" technique, which he had previously used in the tape pieces It's Gonna Rain (1965) and Come Out (1966), to live performance.

Reich further developed this technique in pieces like Violin Phase (also 1967), Phase Patterns (1970), and Drumming (1971).

History

Piano Phase represents Steve Reich's first attempt to apply his "phasing" technique. Reich had earlier used tape loops in It's Gonna Rain (1965) and Come Out (1966), but wanted to apply the technique to live performance. [1] Reich carried out a hybrid test with Reed Phase (1966), combining an instrument (a soprano saxophone) and a magnetic tape.

Not having two pianos at his disposal, Reich experimented by first recording a piano part on tape, and then trying to play mostly in sync with the recording, albeit with slight shifts, or phases, with occasional re-alignments of the twelve successive notes against each other. Reich found the experience satisfying, [2] showing that a musician can phase with concentration.

With the premiere of Reed Phase at Fairleigh Dickinson University in early 1967, Reich and a musician friend, Arthur Murphy, had the opportunity to attempt Piano Phase with two pianos in live concert. Reich discovered that it was possible to dispense with tape and phase without mechanical assistance. Reich experimented phasing with several versions, including a version for four electric pianos titled Four Pianos dating from March 1967, before settling on a final version of the piece written for two pianos. [2] The first performance of the version for four pianos was given on March 17, 1967 at the Park Place Gallery, with Art Murphy, James Tenney, Philip Corner, and Reich himself. [3]

Composition

Reich's phasing works generally have two identical lines of music, which begin by playing synchronously, but slowly become out of phase with one another when one of them slightly speeds up. In Piano Phase, Reich subdivides the work (in 32 measures) into three sections, with each section taking the same basic pattern, played rapidly by both pianists. The music is made up, therefore, of the results of applying the phasing process to the initial twelve-note melody—as such, it is a piece of process music. The composition typically lasts around 15-20 minutes.

First section

The section begins by both pianists playing a rapid twelve-note melodic figure over and over again in unison (E4 F♯4 B4 C♯5 D5 F♯4 E4 C♯5 B4 F♯4 D5 C♯5). The pattern consists only of 5 distinct pitch classes.

After a while, one pianist begins to play slightly faster than the other. When this pianist is playing the second note of the figure at the same time the other pianist is playing the first note, the two pianists play at the same tempo again. The process is repeated until the process has gone full circle, and the two pianists are playing in perfect unison.

Second section

The second pianist then fades out, leaving the first playing the original twelve-note melody. The first pianist adjusts the bottom part to a four-note motif, which changes the pattern to an 8-note repeating pattern. The second pianist re-enters, but with a distinct 8-note pattern. The phasing process begins again; after the full eight cycles, the first pianist fades out, leaving one eight-note melody playing. The section ends at measure 26.

Third section

The last section introduces the simplest pattern, now in 4/8 meter, built from final four notes of the melody from the previous section, [4] and having only four distinct pitch classes. The other pianist re-enters, the phasing process restarts, and ends when both pianists return to unison. The phase cycle is repeated ad libitum from eight to sixty times according to the score.

Analysis

Piano Phase is an example of "music as a gradual process," as Reich stated in his essay from 1968. [5] In it, Reich described his interest in using processes to generate music, particularly noting how the process is perceived by the listener. (Processes are deterministic: a description of the process can describe an entire whole composition. [5] In other words, once the basic pattern and the phase process have been defined, the music consists itself.)

Reich called the unexpected ways change occurred via the process "by-products", formed by the superimposition of patterns. The superimpositions form sub-melodies, often spontaneously due to echo, resonance, dynamics, and tempo, and the general perception of the listener. [6]

According to musicologist Keith Potter, Piano Phase led to several breakthroughs that would mark Reich's future compositions. The first is the discovery of using simple but flexible harmonic material, which produces remarkable musical results when phasing occurs. [4] The use of 12-note or 12-division patterns in Piano Phase proved to be successful, and Reich would re-use it in Clapping Music and Music for 18 Musicians . Another novelty is the appearance of rhythmic ambiguity during phasing of a basic pattern. The rhythmic perception during phasing can vary considerably, from being very simple (in-phase), to complex and intricate. [6]

The first section of Piano Phase has been the section studied most by musicologists. A property of the first section of phase cycle is that it is symmetric, which results in identical patterns half-way through the phase cycle. [6]

Performance

The piece is played by two pianists without breaks at any stage. A typical performance may last around fifteen to twenty minutes. Reich later adapted the piece for two marimbas, typically played an octave lower than the original.

In dance, the piece was used in 1982 by the Belgian choreographer Anne Teresa De Keersmaeker as part of one of her work Fase, which became a cornerstone of contemporary dance.

In 2004, a college student named Rob Kovacs gave the first solo performance of the piece at the Baldwin Wallace Conservatory of Music. Kovacs played both piano parts at the same time on two different pianos. Reich was in the audience for this world premiere performance. [7] [8] Others, including Peter Aidu, Leszek Możdżer, [9] and Rachel Flowers [10] have also given solo performances of this piece.

In 2016, a performance given by harpsichordist Mahan Esfahani at the Kölner Philharmonie was disrupted by audience members who clapped, whistled and shouted 'speak German' during the first minutes of the performance, which had to be abandoned. [11] [12]

Stephen Michael Reich is an American composer who is known for his contribution to the development of minimal music in the mid to late 1960s. Reich's work is marked by its use of repetitive figures, slow harmonic rhythm, and canons. Reich describes this concept in his essay, "Music as a Gradual Process", by stating, "I am interested in perceptible processes. I want to be able to hear the process happening throughout the sounding music." For example, his early works experiment with phase shifting, in which one or more repeated phrases plays slower or faster than the others, causing it to go "out of phase." This creates new musical patterns in a perceptible flow.

<span class="mw-page-title-main">Tape loop</span> Loops of magnetic tape to create patterns or sounds

In music, tape loops are loops of magnetic tape used to create repetitive, rhythmic musical patterns or dense layers of sound when played on a tape recorder. Originating in the 1940s with the work of Pierre Schaeffer, they were used among contemporary composers of 1950s and 1960s, such as Éliane Radigue, Steve Reich, Terry Riley, and Karlheinz Stockhausen, who used them to create phase patterns, rhythms, textures, and timbres. Popular music authors of 1960s and 1970s, particularly in psychedelic, progressive and ambient genres, used tape loops to accompany their music with innovative sound effects. In the 1980s, analog audio and tape loops with it gave way to digital audio and application of computers to generate and process sound.

Music for 18 Musicians is a work of minimalist music composed by Steve Reich during 1974–1976. Its world premiere was on April 24, 1976, at The Town Hall in the Midtown Manhattan Theater District. Following this, a recording of the piece was released on the ECM New Series in 1978.

Violin Phase is a musical work written by minimalist composer Steve Reich in October 1967.

Minimal music is a form of art music or other compositional practice that employs limited or minimal musical materials. Prominent features of minimalist music include repetitive patterns or pulses, steady drones, consonant harmony, and reiteration of musical phrases or smaller units. It may include features such as phase shifting, resulting in what is termed phase music, or process techniques that follow strict rules, usually described as process music. The approach is marked by a non-narrative, non-teleological, and non-representational approach, and calls attention to the activity of listening by focusing on the internal processes of the music.

Come Out is a 1966 piece by American composer Steve Reich. Reich was asked to edit down tape footage into a form of collage for a benefit for the Harlem Six and Come Out was a byproduct of the collage's production. The Harlem Six were six black youths arrested for a murder of Margit Sugar, a Hungarian refugee, in Harlem in the weeks following the Little Fruit Stand Riot of 1964. Only one of the six was responsible while the lead witness is generally considered the actual perpetrator. Truman Nelson, a civil rights activist and New Yorker who had asked Reich to compose a sound collage that was separate from Come Out, gave him a collection of tapes with recorded voices to use as source material. Nelson agreed to give Reich creative freedom with the tapes that he presented him for the sound collage. Come Out was a loop of four seconds from the more than 70 hours of tapes Nelson presented to Reich.

The Nocturnes, Op. 15 are a set of three nocturnes for solo piano written by Frédéric Chopin between 1830 and 1833. The work was published in January 1834, and was dedicated to Ferdinand Hiller. These nocturnes display a more personal approach to the nocturne form than that of the earlier Opus 9. The melodies and emotional depth of these nocturnes have thus been thought of as more "Chopinesque."

<span class="mw-page-title-main">Phase music</span> Compositional technique

Phase music is a form of music that uses phasing as a primary compositional process. It is an approach to musical composition that is often associated with minimal music, as it shares similar characteristics, but some commentators prefer to treat phase music as a separate category. Phasing is a compositional technique in which the same part is played on two musical instruments, in steady but not identical tempi. Thus, the two instruments gradually shift out of unison, creating first a slight echo as one instrument plays a little behind the other, then a doubling effect with each note heard twice, then a complex ringing effect, and eventually coming back through doubling and echo into unison.

Reed Phase, also called Three Reeds, is an early work by the American minimalist composer Steve Reich. It was written originally in 1966 for soprano saxophone and two soprano saxophones recorded on magnetic tape, titled at that time Saxophone Phase, and was later published in two versions: one for any reed instrument and tape, the other for three reed instruments of exactly the same kind. It was Reich's first attempt at applying his "phasing" technique, which he had previously used in the tape pieces It's Gonna Rain (1965) and Come Out (1966), to live performance.

New York Counterpoint for amplified clarinet and tape, or 9 clarinets and 3 bass clarinets, is a 1985 minimalist composition written by American composer Steve Reich. The piece, intended to capture the throbbing vibrancy of Manhattan, is notable for its ability to imitate electronic sounds through acoustic instrumentation.
