The Czechoslovakian composer Jindrich Feld (b.1925) composed Introduzione, Toccata e Fuga per Flauto Solo, for the Italian flutist Roberto Frabbriciani. Feld's Introduzione is from his third style period. This work may be labeled as a synthesis of the experiments and experiences that have enabled him to create his own mature style of expression.

This study traces the significant developments in the late nineteenth and early twentieth centuries which led to the development of electronic music and increased writing for percussion. Whether by coincidence or premeditation, the field of percussion in Western culture and electronic music share many parallel aspects in their history. Carlos Chavez, Edgard Varese and John Cage foresaw a time when electronic music would allow composers to realize compositions with ease, provide new sounds to the spectrum of possible material for pieces and aid in the conception of works. Significantly, these same composers were important figures in the development of percussion composition. In many ways, Lejaren Hiller's Machine Music can be seen as a culmination of the developments which had been taking place in the history of electronic music and percussion music. A product of the innovations in both fields, it poses some formidable problems for the performers. This study will give some background into its composition, examine its structure and deal with its performance problems.

Two of the leading methodologies for spatializing audio over multiple channels include non-real-time multi-track tape and variations of real-time systems that often involve complex configurations of hardware. Of the latter, composers relying on MIDI as a control source have used pairs of sound modules, effects units and automation capable mixers to achieve spatialization over four loudspeakers. These systems typically employ intensity panning, Doppler shifts and reverberation. The present research details the development of a compact spatialization system using a MAX patch controlling a Kurzweil K2500 sampler. This system supports real-time diffusion of up to six simultaneous sound files over eight loudspeakers while incorporating intensity panning, Doppler shifts, delays and filtering. The MAX patch allows composers to choose from several automatic sound spatialization trajectories or to use the mouse to draw and store their own trajectories for later playback. The piece, Circumfusion, is an eighteen-minute composition of electroacoustic music utilizing this spatialization system.

When Alberto Ginastera's oeuvre is viewed as a whole, an essential continuity between compositional ideas often appears in different works. This is especially apparent in the three piano sonatas, where each sonata represents an evolution and a condensation of ideas occurring in the previous one. The evolution of ideas throughout the three sonatas takes place through two primary processes. The first is a shift in cultural focus from reliance on Ibero-American material in the first sonata (1952) to Amerindian in the second (1981), to a synthesis of the two cultural elements in the third (1982). The second means of evolution from sonata to sonata is through a process of symmetrization. Along with constructions using symmetrical scales, material in each of the three sonatas is subjected to various symmetrical procedures which correspond musically to basic geometric symmetry types or operations (bilateral, rotational, and translatory, for instance). The decreasing number of movements evidences a negative dilatation of material, moving from four movements in the first sonata to three in the second, to one in the third. In each case, corresponding material from the previous sonata is integrated into the following sonata. Both independently and as a group the three piano sonatas exhibit …

This study demonstrated that the piano, a typical Western instrument, became the Chinese composer's tool for expressing the sound ideals and tone qualities that are intrinsic to Chinese music. A new musical idiom was created in these piano compositions, an idiom that combined Western compositional techniques and traditionally-based Chinese ideals.

This dissertation proposes that the Sonatine broadly unfolds a kinetic structure that stems from the traditional tension-relief model and, consequently, its dependence on tradition proves much deeper than Boulez would acknowledge.

The lecture was presented on November 18, 1991. This presentation focused on the only two compositions for solo flute and orchestra by Ernest Bloch. Written during the last three years of the composer's life, the pieces are representative of his last style period. While Suite Modale is neobaroque in style, Two Last Poems is much more subjective. Together they represent a synthesis of many of the stylistic characteristics of Ernest Bloch. The musical parameters discussed included form, melody, texture, rhythm, harmony, and expressive devices.

The six-movement work is scored for two violins, a viola, and a violoncello. A new approach toward the decision making of the compositional process is revealed which structures the parameters of the composition along an arbitrary frame of reference. This reference is selected prior to composition and influences every aspect of the work. The reference chosen is an existing musical work used in quotation and for stylistic modeling, paraphrase, and variation. Consonance, dissonance, and thematic development are defined in terms of this source.

This study discusses how cultural and social aspects of contemporary Swedish society impact the musical arts. It contains biographical information on representative Swedish composers, and analyzes technical and structural elements of their compositional styles. Finally, it recommends performance practice considerations regarding technical and interpretive details in Tommy Zwedberg's Face the Music for trumpet and prepared audio tape, Folke Habe's Shazam for unaccompanied trumpet, and Bo Nilsson's Infrastruktur for brass quintet.

The present study does not attempt to present a complete or exhaustive survey of the myriad spatial orchestrational devices occurring in the symphonic and operatic repertoire. Rather, the study is limited to an examination of the specified use of the trumpet as an offstage instrument in selected representative works. The study's purpose is to identify trends in the use of this orchestrational device, to serve as an aid to the trumpeter in matters of interpretation, and to provide a practical reference for the solution of acoustical and technical problems common to the performance of spatially conceived music in the orchestral literature.

John Corigliano (b. 1938) is a contemporary American composer who has in the last twenty years established himself as a composer whose versatility and accessibility are appreciated by a wide range of audiences. He has labeled himself an eclectic composer who unashamedly borrows from other musical styles and periods in an effort to create works that appeal to a variety of listeners. He has been mentioned along with George Rochberg, George Crumb, and Jacob Druckman as an advocate of the post-modern movement in contemporary American music, a trend that has been crucial to the development of contemporary concert music. The purpose of this study is to examine the two solo piano works of Corigliano in terms of style, structure, and musical influences. The Etude Fani-agy (197 6) is a set of five etudes, performed without pause. The etudes are unified through an elaborate use of thematic transformation in which a row-like idea generates most of the material. The keyboard writing is varied and dramatic, with similarities to Debussy, Bartok, Prokofiev, and Copland. Fantasia on an Qstinato (1985), commissioned for the van Cliburn International Piano Competition, is an atmospheric tone poem that transforms the theme from Beethoven's Symphony no« 7 (second …

Jonah's Prayer is a choral work for solo tenor, a mixed choir of not fewer than 30 members, two pianos and a few percussion instruments to be played by choir members. The piece lasts about 13 minutes; it is a work intended for church choir use but could be performed in other venues as well.
