To provide a background for this study, an attempt has been made to correlate the facts known about Playford's life and work. The examination of the treatise has two main objectives: 1. to give an exposition of the material presented by Playford (which includes not only theory of music with examples, but also instructions on singing and on playing the viol and the violin, as well as a number of musical compositions); and 2. wherever possible, to discover the sources used by Playford in writing the treatise.

This work is a study of the historical and social background, the life and the compositions of Heinrich Schutz.

It is interesting to note that several of Ravel's compositions for the piano were successful only after he had orchestrated them. Ravel, a pianist, had a natural gift for orchestration, and when writing for the piano he seems to have projected his thoughts to the orchestra; thus some of his works are more successful' for the orchestra than for the piano. Since he orchestrated several of his own piano compositions, these present an excellent opportunity for a study of his orchestrations.

The harmony of Vaughan Williams defies classification in terms of traditional harmony alone, making use as it does at times, of structures of superposed fourths, so-called "added-note" chords, and random sonorities, as will appear. Therefore, the chords will be placed into two principal categories of usage, traditional and non-traditional.

This thesis provides a brief history of opera as well as analysis of the operas of Giuseppe Verdi.

It is the purpose of this thesis to offer some pertinent information in the form of a documentary symposium and analytical study in which historical and technical matters relative to Beethoven's fugal techniques in his choral compositions will be presented. References to specific musical examples in this composer's works will be illustrated by diagrammatic and verbal analyses, and correlated with the pagination of the scores of his complete works as published by Breitkopf and Hartel.

The purpose of this thesis is to trace the history of the trumpet in chamber music through the first half of the 20th century. It aims to discuss the technical advances in the instrument and demonstrate the importance of the trumpet in this medium. Chamber music is defined, in this thesis, as all serious instrumental music for two or more instruments played with one instrument to a part. The selections have been chosen on the basis of recognized merit of the composer, the variety of instrumentation, and the availability of music.
