The six piano suites of R. Nathaniel Dett (1882-1943) constitute a substantial body of piano music that illustrates the musical development of an important, but historically neglected American musician. Dett was a seminal figure in the preservation and study of spirituals, both as a writer and choral leader, and as a great teacher and inspirer of African-American musicians in the generations that followed him. Educated at Oberlin and Eastman, he was lauded as the first American composer to fuse Negro folk music with European art music tradition. The writing of a series of like-genre works over a composer's lifetime, reflecting stylistic changes and a deepening world view, is a special event in the history of keyboard music. Unfortunately, Dett's piano music is rarely performed except for the second of the suites, In the Bottoms. Although his importance to African-American musical history is generally acknowledged by musicologists, his works for piano have remained largely unexplored by performers. Dett's eclectic pursuits included poetry, the Rosicrucian Society, and religion. This study explores the connections between the suites and other musical styles and traditions, Dett's many extra-musical interests, and his performing life. It also offers some possible explanations for the relative lack of attention received by his piano music. This study incorporates research from readily-available sources, as well as the Nathaniel Dett archives at the Niagara Falls New York Public Library and Hampton University. The first three chapters give an overview of Dett's style and influences, as well as a description of how his musical language developed from his first suite, Magnolia (1912), to his last, Eight Bible Vignettes (1941-43), written at the end of his life. Each suite is examined individually in detail in the following six chapters. It is hoped that this work will stimulate appreciation of Dett's piano music and lead to more frequent performances. Its goal is to give to the reader the same sense of admiration and joy that the author's exploration of these works has given him. / Music Performance

This study develops a method for analyzing jazz piano music, primarily focusing on the era 1935-1950. The method is based on axiomatic concepts of jazz harmony, such as the circle of fifths and root position harmonies. 7-10 motion between root and chordal seventh seems to be the driving force in jazz motion. The concept of tritone substitution leads to the idea of a harmonic level, i.e., a harmony's distance from the tonic. With this method in hand, various works of music are analyzed, illustrating that all harmonic motion can be labelled into one of three categories. The ultimate goal of this analytic method is to illustrate the fundamental harmonic line which serves as the harmonic framework from which the jazz composer builds.

The purpose of this thesis is to discuss and give a descriptive analysis of twelve of the twenty-four preludes written by Claude Debussy. This paper also includes a brief history of preludes as well as possible influences upon Debussy and his compositions.

The Revolution of 1910 in Mexico marked a great political and social upheaval. At the same time a recasting of Mexico's music occurred. Modern Mexican music is a unique combination of the influence inherited from Europe and the indigenous music of the country. This work attempts to trace the development of that combination. Chapter I gives a background of music in Mexico through Pre-Cortesian times, the colonial period and the operatic nineteenth century. Chapter II deals with the men who shaped present day music in Mexico. Chapter III is an analysis of selected twentieth century piano works. The analysis shows the tendencies of ten Mexican composers in their use of melody and rhythm. It includes a discussion of harmonic structure and tonality. The composers whose works were chosen for consideration in the analysis range from Manuel M. Ponce, considered the father of modern Mexican music, to Carlos Chavez, recognized as the outstanding exponent of music in Mexico today.

We propose a Bayesian monaural source separation system to extract each individual tone from mixture signals of piano music performance. Specifically, tone extractions can be facilitated by model-based inference. Two signal models based on summation of sinusoidal waves were employed to represent piano tones. The first model is the traditional General Model, which is a variant of sinusoidal modeling, for representing a tone for high modeling quality; but this model often fails for mixtures of tones. The second model is an instrument-specific model tailored for the piano sound; its modeling quality is not as high as the traditional General Model, but its structure makes source separation easier. To exploit the benefits offered by both the traditional General Model and our proposed Piano Model, we used the hierarchical Bayesian framework to combine both models in the source separation process. These procedures allowed us to recover suitable parameters (frequencies, amplitudes, phases, intensities and fine-tuned onsets) for thorough analyses and characterizations of musical nuances. Isolated tones from a target recording were used to train the Piano Model, and the timing and pitch of individual music notes in the target recording were supplied to our proposed system for different experiments. Our results show that our proposed system gives robust and accurate separation of signal mixtures, and yields a separation quality significantly better than those reported in previous works. / What makes a good piano performance? An expressive piano performance owes its emotive power to the performer's skills in shaping the music with nuances. For the purpose of performance analysis, nuance can be defined as any subtle manipulation of sound parameters including attack, timing, pitch, loudness and timbre. A major obstacle to a systematic computational analysis of musical nuances is that it is often difficult to uncover relevant sound parameters from the complex audio signal of a piano music performance. A piano piece invariably involves simultaneous striking of multiple keys, and it is not obvious how one may extract the parameters of individual keys from the combined mixed signal. This problem of parameter extraction can be formulated as a source separation problem. Our research goal is to extract individual tones (frequencies, amplitudes and phases) from a mixture of piano tones. / Szeto, Wai Man. / Adviser: Wong Kim Hong. / Source: Dissertation Abstracts International, Volume: 73-03, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2010. / Includes bibliographical references (leaves 120-128). / Electronic reproduction.
