In four pieces selected from the late Baroque repertoire, the "Allemanda" from Corelli's Sonata for Violin and Continuo, Opus 5, No. 8, the "Allemande" from Bach's Clavierubung, Partita, No. 1, the chorus, "Thy Right Hand, Oh Lord" from Handel's Israel in Egypt, and the aria duetto, "Mein Freund ist Mein" from Cantata No. 140, Wachet Auf, by Bach, harmonic, melodic and motivic parameters are analysed and graphed so that their integration in each work is readily observable. Then, in an attempt to establish more general formal models similar to those developed by Arnold Schoenberg, Erwin Ratz, and William E. Caplin for the classical style, recurring patterns of integration are noted. Of special significance is the prominence of acceleration processes in each piece and their diversity, both in the parameters involved, as well as in the structural levels on which these processes operate.

Thesis(M.Mus.) -- Stellenbosch University, 1987. / VOORWOORD Die twintigste eeu beleef 'n besondere belangstelling in die outentieke uitvoering van ou musiek en dit is 'n studieveld wat reeds uitgebreid nagevors is. Desondanks bestaan daar steeds baie vraagstukke aangaande sekere uitvoeringspraktyke en styltipes en hoe ouer die musiek, hoe meer problematies word 'n outentieke uitvoering, veral as gevolg van die groot verskille tussen die moderne en ou instrumente, die speeltegnieke en die dikwels ontoereikende notasie. Die teoriee wat die twintigste eeuse musici aangaande die uitvoeringspraktyke geformuleer het, is hoofsaaklik gebaseer op ou geskrifte, verhandelinge en onderrigboeke uit die onderskeie styltydperke. Daar bestaan baie teenstrydighede tussen hierdie teoriee, veral met betrekking tot die musiek van die Barokperiode. Die uitvoering van musiek van die Klassieke en veral die Romantiese periodes is minder problematies en die redes hiervoor is hoofsaaklik die volgende: Die notasiesisteem het reeds tydens die Hoog-Klassieke tydperk tot sy huidige vorm ontwikkel. Verder het musiekkritiek en -geskiedskrywing segert die agtiende eeu toenemend meer aandag geniet en bestaan daar dus meer inligting aangaande uitvoeringspraktyke. Ten spyte daarvan dat hierdie na vorsing reeds dekades gelede begin het, is daar steeds groot onkunde daaromtrent en word daar dikwels min aandag gegee aan die outentieke uitvoering van ou musiek. Hierdie studie is 'n paging om die navorsing wat reeds gedoen is krities te ondersoek en 'n moontlike samevatting daarvan te gee. / Digitized at 300 dpi B/W PDF format (OCR), using ,KODAK i 1220 PLUS scanner.

This document explores some music of the Baroque era. Specifically, it is concerned with eighteenth century musical articulation, ornamentation, and the type of flute in use at that time, which we now call the baroque flute. The term articulation refers to the entire subject of how a note is begun, the type of articulation syllable used, and how notes are grouped together. In the Baroque period melodies were embellished with certain standard ornaments. The proper performance of these ornaments was the subject of much discussion and writing. At the end of this document the reader will find a selected bibliography which includes some of these writings. There are many types of ornaments. This study will be concerned with some of them: the trill, mordent, appoggiatura, grupetto, messa di voce, and flattement. Vibrato at that time was considered to be an ornament, and will be included as such.

This paper studies the formal ambiguity that arises when a closing gesture occupies a beginning location in the instrumental works of Haydn, Mozart, and Beethoven. Accordingly, I am interested in those formal areas within a piece that are concerned with the functions of either "beginning" or "ending." / I first present a systematic survey of the theoretical principles underlying the formal functions of beginning and ending in this style. I then show some specific examples of typical cadences and of initial units that imitate them. Next, I focus on the "main theme," observing how the function of "beginning" is performed by a "closing initial idea" and then, how the main theme's cadences express their proper function. Finally, I study what happens in other locations such as the return of the main theme, the cadence closing the form, and post-cadential material.

The basic purpose of this dissertation is to provide the trombonist of today with a realization concerning ornamentation practices of the baroque period, and to supply trombonists and trombone instructors with the resources necessary to include the appropriate ornaments in a performance of baroque music.Chapter 1 is concerned with the ornamentation practices of Italy and France, the two most influential nations in the development of a mature style of baroque performance. The Italian tradition of free embellishment is presented and compared with the French tradition of composers' providing specific ornaments for their music. The author's choice of ornaments presented in the sonatas of Galliard, Marcello, and Vivaldi in Chapters 4, 5, and 6 is based on the prominence of these two styles.Chapter 2 is a presentation of the three most popular categories of embellishments employed during the baroque period. The families of appoggiaturas, trills, and mordents, are notated together with suggestions for their proper expression and execution on the trombone. Examples are taken from the embellished sonatas presented later in this study, using measure numbering to identify their placement withineach measure.Chapter 3 is an essay dealing with the art of trilling on the trombone. The overtone series is explained in regard to the formation of thirds, and to the proper notation necessary to adequately perform trills of major and minor thirds. A section concerning the use of the "F" attachment for performing baroque trills is highlighted with examples identifying several valve and slide combinations that favor the execution of major and minor seconds on the trombone.Chapters 4, 5, and 6 are an application of baroque embellishments to eighteen sonatas from the baroque period. Each of the ornaments is notated and placed within the context of the music. The musical compositions chasen for this study represent the Six Sonatas for Bassoon and Harpsichord Johann Ernst Galliard, Six Sonatas for Viloncello and Piano by Benedetto Marcello, and Six Sonatas for Violoncello and Figured Bass by Antonio Vivaldi.
