Anthony Davis on Earl Howard’s Granular Synthesis

Next Thursday December 12, Earl Howard and Anthony Davis present Solo, Duo, & Quartet music with Mark Dresser and JD Parran.  Here is an article by Anthony Davis, discussing Earl Howard’s innovative approach to live performance using granular Synthesis. 


I first encountered Earl Howard’s music in 1980 with his work V & T, which was composed for the violinist Shem Guibbory. I was greatly impressed by his command of texture and the subtle interaction between the soloist and the tape. Initially I felt the soloist was controlled by the tape music but the piece fostered a nuanced performance with a refreshing attention to detail within a relatively restricted musical realm. I felt a connection to this new music because it resonated with my desire to create ensemble music in which compositional aims could be achieved through directed improvisation. I was pleased when he decided to create a new work for piano and tape, Particle W. Particle W was the beginning of a creative collaboration with Earl that continues to this day.

Working on Particle W, I was introduced to a new vocabulary of musical terms that were certainly unique in the improvised sphere. His directions for the piano were very specific, not necessarily about pitch or even rhythmic gesture, but about the relationship of the “improvised” material to the tape music. The tape music moved through various textures divided into sections that featured subtle transitions. I had to negotiate very specific musical identities whether playing points with space, bandwidth games, or the beating tones of microtonal harmonics. The terminology for the piano textures came from electronic music. Directions were not metaphoric but a concrete design of interaction and play within a dynamically evolving musical frame. I was always aware of the fixity of tape music, the idea that the piece provided a clock, an organization and frame for the timing of events. This was not altogether different from playing a concerto where the performer must not only realize the inherent structure of the piece but reveal the structure as a new discovery for each performance. The piece excited me because it shattered the anachronistic idea of improvisation and composition as an oppositional binary. Howard’s innovations suggest that music can be realized in a continuum of interaction and design.

The only limitation in Particle W and Monopole, the subsequent work that Earl created for piano duet with Ursula Oppens and me, was that ultimately the tape maintained control. It dictated the duration and succession of events. The sounds and textures for Particle W, Monopole, and the tape composition Pele’s Tears were all created with a Serge system that Howard describes as an analog computer. With new technology, particularly the Kurzweil K2600, he could create music in real time. The music could be truly interactive within a complex, replicable design. The music could flow through textures and processes that were never static. Textures and ideas could transform and evolve over time. Howard did not conceive sound as an environment or a sonic field but as dynamic forces in motion. The sounds and textures could have behaviors and probabilities rather than static, unrelenting fixity.

In many respects Earl Howard’s music is an anomaly that resists categorization and the seductiveness of genre. He is an important force in improvised music and yet his work employs complex structures and rigorous transitions of sound and texture. His electro-acoustic music is realized with a Kurzweil K2600 that for Howard is not merely a keyboard synthesizer, but as he has described, an open system, a computer with a most effective interface with modules and a key map that enable more freedom in the composer’s creation of textures. The keys, pedals, and sliders on the instrument are in effect switches that can accomplish various musical tasks determined by the composer. Howard does not play the Kurzweil as a mere keyboard; the tactile interface with it allows for a musicality and subtlety that cannot be achieved by most artists working on laptops that feature a visual interface. Howard’s performances on the Kurzweil are embodied and the physical relationship of performer to music and action is self-evident. His painstaking programming of the Kurzweil creates a space for the intuitive mind and the improviser’s imagination. I have witnessed experts in computer music who are stunned by what he is able to achieve with effects and processes that would be impossible for the laptop in realtime.

Howard’s music challenges many assumptions about electro-acoustic music and the role of electronic music. In most electro-acoustic music today the electronic elements are limited to either an attenuation of the instrument in so-called hyper-instruments or in the creation of static environments that provide background for acoustic instruments. Very few composers working in computer music today are interested in new sounds or textures or sound transformation and are more concerned with the movement of sound in virtual spaces, the concert hall as a projected set of headphones.

Earl Howard grew up in Los Angeles. As a child, he was influenced by film music and he was fascinated by the way music and sound in films provided shifting perspectives, moving from large masses of sound like a posse on horseback to an individualized perspective of a bullet whistling overhead. Films provided sound in constant motion forming shifting points of view, from the dense to the spare, from the echoes of space to the violent confrontation. He attended California Institute of the Arts where he studied under the composer Morton Subotnick and the celebrated improviser Buell Neidlinger. Howard also studied saxophone with Phil Sobel. He is a virtuoso on the saxophone, performing on the alto as well as the soprano saxophone and the saxello. Sobel abhorred patterns and licks and emphasized the disruption of patterns by asking for random pitches during exercises. This served Howard well in the future because his music always engages in creative disruption, not allowing the improviser to dwell in the known clichés and patterns of playing and demanding that the performer listen and understand the movement and transformation of texture within the composition.

In the three solo works presented on Granular Modality, one can observe the striking continuity of Howard’s aesthetic approach. All three pieces employ a flexible script of material that transforms and modulates from texture to texture. Each section in the composition represents a complex sound world that is not simply multiphonics or sub-harmonics, for example, but an exchange, an interplay that is both directional in terms of an overall sense of form and discursive in its oppositional characteristics. The discursive elements in Howard’s playing on the saxophone and on the synthesizer convey a restless approach toward material. Musical material and texture always change and evolve. On the synthesizer this is accomplished with a scripted succession of programs, textures, and behaviors that can overlap and be revealed over time. The scripted flow of events creates a coherent overall structure that is malleable in terms of duration and nuance.

Distinction between the improvised and the composed becomes irrelevant, as the order of events, the script, remains the same as the details are revealed in the action of improvisation. The binary of composition and improvisation is an anachronism and inadequately describes a creative process that embraces immediacy and formal complexity.

Bird 3 (2006), a solo work for Kurzweil, opens the recording. The piece employs sharp contrasts of musical material with abrupt changes of texture. In a way the piece has a nostalgic quality as it negotiates a virtual history of electronic music from the Columbia-Princeton sine waves to musique concrète to the exploration of granular synthesis and noise. The piece is breathtaking in its virtuosity, filled with surprise and the unexpected. At times the piece builds with rhythmic momentum and then collapses into a mass of sound like a flock of birds drifting in and out of formation moving across a stereo field. Bird 3 has a unique spaciousness and in the piece Howard explores silences that disturb the expectation and predictability of cross-fades. Strasser 60 (2009) is the other Kurweil solo on the recording. In both pieces the listener is startled by the variety of sound and texture that are complexly defined, hardly ever sounding like a conventional instrument. In the opening sections of Strasser 60 the transformations are less abrupt, with large, dense textures that vie for attention. Textures collide and are augmented by harmonics and colorful elaboration with the occasional introduction of tonality and downward moving glissandi. This reveals Howard’s mastery in orchestration as the piece finally resolves into a pedal-point drone that dissipates into a sheen of harmonics, a sublimation of the tonal center.

2455 (2009) is a work for alto saxophone featuring the composer. Works for solo saxophone remain an important facet of Howard’s music. This piece follows his work on 5 Saxophone Solos. Unlike Anthony Braxton and Roscoe Mitchell, two other important composers who performed music for solo saxophone, Howard creates longer, more elaborate musical structures that are multi-thematic, employing a variety of extended techniques. He never limits himself to one idea in a piece. The composition morphs and transforms, negotiating contrasting textures and sounds.

The piece opens with breathy sub-harmonics creating a microtonal melody. He uses his glissando technique with an oblique nod to Johnny Hodges. Howard’s control of his instrument is especially impressive in his attention to dynamics and timbre, employing soft multiphonic textures and sub-tone melodies. Howard’s process of composition in his solo saxophone works is similar to his approach on the synthesizer. He explores contrasting sections of material in an array of varying approaches to technique and sound. Listening to his performance one often arrives at unexpected places like the folksy, Albert Ayler reference in the middle of the solo. The solo has a strong sense of structure while revealing a playfully melodic vision.

Crupper (2009) features Miya Masaoka on koto with the composer on synthesizer. Crupper begins with the koto alone and the listener is struck by the sense of space. The koto plays around D minor emphasizing the flat fifth, A-flat, like a blues. Later, the koto emphasizes a pentatonic modal scale introducing the E-flat against the D. This establishes a tonal center that will be felt throughout most of the piece. The music takes its time to reveal itself. The synthesizer enters as a shadow of the koto as Howard begins the processing of the koto. Slowly the interaction becomes more rhythmic with repeating figures in the koto but the synthesizer never overwhelms the acoustic koto as Masaoka moves to bowed figures on the koto and later percussive sounds beating on the wood. In the beginning sections of the piece the synthesizer plays a more subordinate role, mirroring and attenuating the melodic figures of the koto. This piece is rather unique in Howard’s music with its slow, almost ritualistic unfolding and with the presence of a predominant tonal center. The synthesizer gently disturbs and extends the tonality, slowly moving toward stochastic textures, less tonally defined, juxtaposed against the prevailing D tonal center in the
koto. When Masaoka moves to more percussive sounds, the gravitational pull of tonality begins to abate as the synthesizer employs more stochastic sounds. Later, Masaoka plays microtonal figures with the synthesizer. The piece concludes with a drone in the synthesizer that recalls the D tonality in the beginning of the piece. The roles of the koto and the synthesizer are effectively reversed at the end of the piece with the koto providing melodic embellishment of the drone. The piece has a fascinating tension between tonality and sound, finding a delicate balance between the stochastic and the melodic.

Earl Howard is a unique voice in new music. His sound world is probably the most rich and varied in electronic music and his playing on the saxophone reinforces a singular vision of music and sound. He draws from a wide range of influences across racial, social, and aesthetic barriers.
New music of the late twentieth century is not only defined by Stockhausen, Cage, and Varèse, but Ayler, Cecil Taylor, Ellington, and even Hank Williams provide the foundation for music today, shattering the anachronistic boundaries between the improvised and the composed. Howard understands the history and development of electronic music without being constrained by its past. His music avoids the facile eclecticism so prevalent in music today. He has created his own idiosyncratic world of sound.
