Carlton Gamer (born February 13, 1929 in Chicago, Illinois) is an American composer and music theorist. He has taught at Colorado College, Princeton University, and the University of Michigan. He studied at Northwestern University and Boston University and privately with Roger Sessions.
Gamer has composed more than seventy works in a variety of categories, including songs, music for dance, solo piano pieces, chamber music, choral works, orchestral works, and computer music.
His music has been featured in New York’s Carnegie Recital Hall (now Weill Recital Hall), the Kennedy Center in Washington, D.C., the Los Angeles County Museum of Art, and in some sixty other venues throughout the U.S. Among its presenters have been the International Society of Contemporary Music, the Society of Composers, Inc., the Current and Modern Consort of the University of Michigan School of Music, the College Music Society, and the John F. Kennedy Center for the Performing Arts—Rockefeller Foundation International Competition for Excellence in the Performance of American Music.
His works have been heard at conferences and festivals in the U.S., among them the WNYC American Music Festival, San Diego International Computer Music Conference, Southwestern Composers Conference, Grand Teton Music Festival, Colorado Contemporary Music Festival, Colorado College Summer Music Festival, and Colorado College New Music Symposium.
Gamer grew up in Champaign-Urbana, Illinois, where his father taught at the University of Illinois, and where at the age of eight he began to study piano with Tanya Kessler and composition with her husband Hubert Kessler, of the faculty of the University of Illinois School of Music, who had been a student of Heinrich Schenker.
From 1942 to 1946 he attended University High School, a laboratory school of Illinois State Normal University (now Illinois State University) in Bloomington-Normal, Illinois, during which time he continued his piano studies with two members of the faculty of Illinois Wesleyan University, first with Stefan Bardas and then with Chester Barris. In 1946 he graduated from University High School as valedictorian.
He went to Northwestern University (B.Mus., 1950), studying theory and composition with Frank Cookson and Anthony Donato and piano with Louis Crowder and Pauline Manchester Lindsey; and Boston University (M.Mus., 1951), studying composition with Gardner Read and musicology with Karl Geiringer. At Boston University he was a graduate assistant, teaching a course in orchestration, and served as research assistant for Read’s Thesaurus of Orchestral Devices.
In New York, 1951-3, he founded a workshop of composer-performers ("The Seven") who met regularly at his home to read through and critique each other’s music; they occasionally performed in public. The members were Sheldon Harnick, violin; Gerard Jaffe, viola; Juliette White, cello; Robert Dorough, recorder, flute, and piano; Eric Katz, recorder, Noel Stevens, clarinet, and himself, piano.
After studying composition privately with Roger Sessions in Princeton, N.J. in 1957, he was invited to be a fellow at the Princeton Seminars in Advanced Musical Studies in 1959 and 1960. His recollection of these seminars is found in his article, ”Milton at the Princeton Seminars.” (See Publications).
He taught at Princeton University as a Visiting Lecturer in Music in 1974, and as a Visiting Professor of Music in 1976 and again in 1981. In 1976 he was appointed a Senior Fellow of the Council of Humanities at Princeton. In the same year, he received a MacDowell Colony Fellowship.
In 1979 he taught at the Salzburg Global Seminar: “Musical Ideas and Musical Institutions” (Session 189) in Salzburg, Austria, with co-faculty Edward Cone, Ruth Katz, Gunther Schuller, Leo Treitler, and Peter Westergaard.
Glenn Giffin in the Denver Post describes Gamer as proposing in Arkhê “a grand program--creation and evolution...The composer uses various means to present this:...by bands of sound and much shifting back and forth between sections in orchestral drones with now one section and then another receiving prominence...[and] through musical cells that get manipulated and expanded to form a large structure.”  According to the American Record Guide "Carlton Gamer's Arkhê freely moves between the poles of tonality and atonality...[its] harmonies [are] often dense to the point of clusters."  Fanfare remarks that, "[This] work opens with a long crescendo on the note A (for Alpha, …) and soon erupts into a Big Bang of fascinating noises." The composer himself describes this piece as using "an externally imposed scheme to derive the duration of each section of the work, [based] upon the miniaturization of a geological time-scale formulated by recent scientific research." 
An evolutionary idea also informs Gamer’s Choros, as described by Mark Arnest in the Colorado Springs Gazette Telegraph: In Part 1 of this work, Bios, the underlying program deals with the evolution of life; in Part 2, Choros, the evolution of humankind. Bios employs phonemic choral Sprechstimme; Choros instantiates stages in the evolution of vocal polyphony from the Mediaeval era to the present.
Nicholas Kenyon in The New Yorker characterizes “Quietly, with feeling” as “a diatonic piece of neo-Mendelssohnian rhapsody. It managed to sound fresh and new; an old language was used, for once, not with purely nostalgic intent.” 
Music critic Gilbert Johns, quoted in the Colorado Springs Gazette Telegraph, “lauds Gamer’s innovative approach to composition, which embraces atonalism and its 12-tone variation, known as serial music. ‘His technique is to rearrange ingeniously what he calls “little pitch cells” into melodic and harmonic entities. He thinks of himself as a composer who has internalized serial technique and given it his own voice...[Thus] he tries to create tonal-sounding music that is serially structured and that gives a richness to the listener’s experience.” 
Edward Rothstein in The New York Times finds in Gamer’s Piano Râga Music “wit merged with severity.”  Reviewing a later performance of the same work, Paul Griffiths in The New York Times describes Piano Râga Music as “hesitating between the worlds of its two dedicatees, Ravi Shankar and Milton Babbitt, before plunging into an immense, flamboyant mix.” 
Gamer himself, in his article “ET Setera” (p. 60), writes of his “interests as a composer of music in ETS 12”—i.e., the twelve-tone equal-tempered system: “In recent years these interests have centered more and more upon the attainment in the pitch domain of a sense of ‘less-than-twelveness’ embedded in ‘twelveness.’ I have become increasingly preoccupied with the properties of certain subcollections of pitches or pitch classes chosen from the universe of pitches within our system and the relationship of such subcollections to that system.” In his “Notes on the structure of Piano Râga Music” (p. 218), for example, Gamer shows how that work employs a 24-tone set generated from a single trichord. In “Lieder to texts by Rainer Maria Rilke” he employs all-trichord sets, each containing an all-interval tetrad, enabling him to embed quotations from tonal music into the serial texture. (Regarding all-interval tetrads, see his article “Microtones and projective planes,” p. 153.) (See Publications.)
Gamer has composed music in equal-tempered systems other than ETS 12. Robin Wilson, in his Gresham College lecture on “Music and mathematics,” discusses Gamer’s use of the 31-tone equal-tempered system in ORGANUM and of the seven-point projective plane in Fanovar.
Work in music theoryEdit
As a music theorist, Gamer has published articles in a number of journals or books on such topics as electronic music, microtonality, the properties of equal-tempered systems containing more or less than twelve tones per octave, and the definition and elaboration of the deep scale property as it applies to such equal-tempered systems (see “Electronic music” and “Some combinational resources of equal-tempered systems”); definitions of the concepts of difference set, block design, and projective plane and applications of these to such equal-tempered systems (see “Deep scales and difference sets,” “Musical block designs,” and “Microtones and projective planes”); the relationship between geometrical duality and musical inversion (see “Microtones and projective planes,” pp. 156–158); invariance matrices and their application to musical composition (see “Fanfares for the common tone”); and musical metatheory, with emphasis on the notion of syntactic models and the prescriptive and postdictive relevance of these to a “theory of composition” (see “The role of the composer as theorist,” “Sketch of a foundation for music theory today,” “Music worlds,” and “Busnois, Brahms, and the syntax of temporal proportions”).
Gamer’s music-theoretical work has been cited in dictionaries and encyclopedias, including the Dictionary of Contemporary Music, Encyclopædia Britannica, Grove Music Online, and New Grove’s Dictionary of Music and Musicians. Further citations appear in Wikipedia articles on the Deep scale property, Triad (music), Trichord, Tetrad (music), Hexachord, 19 equal temperament, and Polite number.
His work has been cited in books and dissertations by Robert Morris, Andrew Mead, Timothy A. Johnson, Jack Douthett et al., and Robert Tyler Kelley, among others, and in numerous articles in a variety of journals, including Journal of Music Theory, Music Theory Spectrum, Perspectives of New Music, Music Analysis, Intégral, Music and Letters, Music Theory Online, Journal of the American Musicological Society, and College Music Symposium.
Gamer has been credited with early contributions to diatonic set theory. Morris, in his article on “Mathematics and the twelve-tone system,” writes: “While the twelve-tone system is no longer isolated from other aspects of music theory, there are many research projects that can be identified to carry on previous work. One obvious direction is to ask what happens when we change the ‘12’ in ‘twelve-tone system’? Carlton Gamer [in ‘Some combinational resources’ (1967) and ‘Deep scales and difference sets’ (1967)] was one of the first theorists to raise such issues. He showed that equal tempered systems of other moduli not only have different structures, they allow different types of combinatorial entities to be built within them.” 
Johnson terms Gamer a “precursor” in this area: “Students who wish to trace the historical development of diatonic set theory might begin with Milton Babbitt, an important american composer and theorist...Later, Carlton Gamer explored some fundamental aspects of the structure and nature of the diatonic collection--in particular, the notion of deep scales...” 
Douthett, Martha M. Hyde, and Charles J. Smith, in their “Introduction” to Music theory and mathematics, also observe that “Milton Babbitt and Carlton Gamer, among others, had noticed intriguing structural properties of the diatonic system when considered as a subset of the equal-tempered chromatic scale.” 
Gamer sometimes illustrates his theoretical ideas with short compositions, as in “Fanfare for the common tone” or “ET Setera.” Wilson Coker, in his review of the latter, writes: “Gamer’s article might almost a be a model for theorists in its subtle blend of the most abstract inquiry along with indications of useful application.”
