Stravinsky seldom explained the intended theme of his works; however, he chose to do so with his Symphony in Three Movements. Stravinsky describes the first movement as a reflection on war films documenting scorched-earth tactics in China. He also states that the third movement is a reflection on the newsreels of goose-stepping soldiers, depicting the plot of the war in its entirety. In his descriptions, Stravinsky left out the second movement of the work. However, the movement already had a life of its own. The second movement expands a theme Stravinsky originally wrote for the movie The Song of Bernadette. The author, Franz Werfel, asked Stravinsky to compose music for the film when the two discussed the work and its central ideas. Although it did not appear in the film, Stravinsky recycled the music for the Symphony in Three Movements. In my opinion, the ideas of hope depicted in Werfel's novel are used by Stravinsky to evoke ideas of the importance of faith in the fallen world. My analysis aims to show the musical means used by Stravinsky to allow the central ideas from The Song of Bernadette to pervade the entirety of the Symphony in Three Movements.

Young Ja Lee (b. 1931) is regarded as one of the most important living female composers in Korea. She leads and contributes to the Korean classical music society as a gifted composer and a dedicated educator. This study focuses on how she has combined Western compositional techniques with elements of Eastern traditional music in some of her compositions, in particular, her Variations pour piano "Umma ya, Nuna ya." An interpretation of her Variations pour piano "Umma ya, Nuna ya" reveals that the composition features many of the particular and sublime aspects of Western compositional techniques in conjunction with traditional Korean music style. This study is an investigation of the interaction and assimilation of these disparate elements. The results of this study may inspire further research into traditional Korean music and bring recognition to important Korean composers, as well as encourage music educators to teach Korean composers' compositions.

Thesis (PhD)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: An area of data mining and statistics that is currently receiving considerable attention is the field of multi-label learning. Problems in this field are concerned with scenarios where each data case can be associated with a set of labels instead of only one. In this thesis, we review the field of multi-label learning and discuss the lack of suitable benchmark data available for evaluating multi-label algorithms. We propose a technique for simulating multi-label data, which allows good control over different data characteristics and which could be useful for conducting comparative studies in the multi-label field. We also discuss the explosion in data in recent years, and highlight the need for some form of dimension reduction in order to alleviate some of the challenges presented by working with large datasets. Feature (or variable) selection is one way of achieving dimension reduction, and after a brief discussion of different feature selection techniques, we propose a new technique for feature selection in a multi-label context, based on the concept of independent probes. This technique is empirically evaluated by using simulated multi-label data and it is shown to achieve classification accuracy with a reduced set of features similar to that achieved with a full set of features. The proposed technique for feature selection is then also applied to the field of music information retrieval (MIR), specifically the problem of musical instrument recognition. An overview of the field of MIR is given, with particular emphasis on the instrument recognition problem. The particular goal of (polyphonic) musical instrument recognition is to automatically identify the instruments playing simultaneously in an audio clip, which is not a simple task. We specifically consider the case of duets – in other words, where two instruments are playing simultaneously – and approach the problem as a multi-label classification one. In our empirical study, we illustrate the complexity of musical instrument data and again show that our proposed feature selection technique is effective in identifying relevant features and thereby reducing the complexity of the dataset without negatively impacting on performance. / AFRIKAANSE OPSOMMING: ‘n Area van dataontginning en statistiek wat tans baie aandag ontvang, is die veld van multi-etiket leerteorie. Probleme in hierdie veld beskou scenarios waar elke datageval met ‘n stel etikette geassosieer kan word, instede van slegs een. In hierdie skripsie gee ons ‘n oorsig oor die veld van multi-etiket leerteorie en bespreek die gebrek aan geskikte standaard datastelle beskikbaar vir die evaluering van multi-etiket algoritmes. Ons stel ‘n tegniek vir die simulasie van multi-etiket data voor, wat goeie kontrole oor verskillende data eienskappe bied en wat nuttig kan wees om vergelykende studies in die multi-etiket veld uit te voer. Ons bespreek ook die onlangse ontploffing in data, en beklemtoon die behoefte aan ‘n vorm van dimensie reduksie om sommige van die uitdagings wat deur sulke groot datastelle gestel word die hoof te bied. Veranderlike seleksie is een manier van dimensie reduksie, en na ‘n vlugtige bespreking van verskillende veranderlike seleksie tegnieke, stel ons ‘n nuwe tegniek vir veranderlike seleksie in ‘n multi-etiket konteks voor, gebaseer op die konsep van onafhanklike soek-veranderlikes. Hierdie tegniek word empiries ge-evalueer deur die gebruik van gesimuleerde multi-etiket data en daar word gewys dat dieselfde klassifikasie akkuraatheid behaal kan word met ‘n verminderde stel veranderlikes as met die volle stel veranderlikes. Die voorgestelde tegniek vir veranderlike seleksie word ook toegepas in die veld van musiek dataontginning, spesifiek die probleem van die herkenning van musiekinstrumente. ‘n Oorsig van die musiek dataontginning veld word gegee, met spesifieke klem op die herkenning van musiekinstrumente. Die spesifieke doel van (polifoniese) musiekinstrument-herkenning is om instrumente te identifiseer wat saam in ‘n oudiosnit speel. Ons oorweeg spesifiek die geval van duette – met ander woorde, waar twee instrumente saam speel – en hanteer die probleem as ‘n multi-etiket klassifikasie een. In ons empiriese studie illustreer ons die kompleksiteit van musiekinstrumentdata en wys weereens dat ons voorgestelde veranderlike seleksie tegniek effektief daarin slaag om relevante veranderlikes te identifiseer en sodoende die kompleksiteit van die datastel te verminder sonder ‘n negatiewe impak op klassifikasie akkuraatheid.

An original composition in three movements for large orchestra. Following the score is a detailed analysis of the work, consisting of an introduction, three sections of analysis devoted to each of the three movements of the composition, and a short conclusion summarizing the analysis.

Estonian composer Veljo Tormis (1930-2017) is one of the most prolific in his country’s history. A significant portion of his writing has been for choirs. Tormis composed most of his works under Soviet rule. During this communist reign of Estonia, Tormis turned to using traditional music. The source material for a large portion of Tormis’ choral output is regilaul, a type of ancient Estonian folk song. In 1991, Estonia gained their independence, thereby allowing Tormis’ compositions to be more easily seen, heard, and performed around the world. This dissertation presents a conductor’s analysis of a set of choral cycles composed by Tormis between 1964 and 1969, Looduspildid, or Nature Pictures. A set of cycles representing all of the seasons and incorporating prominent Estonian poetry, Loodispuldid represents one of Tormis’ most important works. It illustrates Tormis’ maturing style as he utilized a variety of 20th Century techniques like extended tertian harmonies, modal scales, pandiatonicism, clusters, and mixed meters. Tormis also employs his own orchestrally-derived techniques of carefully constructed simultaneous articulations along with cumulative chording. Each cycle contains its own unique style and feel. Sügismaastikud is perhaps the most tonal of the four. Most movements are pandiatonic and one uses the whole tone scale. On a macro level, Sügismaastikud moves from soft in the earlier movements to a fff climax on the final chord of the last movement. Talvemustrid also begins at a very soft dynamic level on a unison D4, grows to multiple ff dynamics throughout, and ends back at a soft dynamic on Db. The cycle is more harmonically adventurous than Sügismaastikud, with consistent chromaticism, octatonic scale, and marked dissonance. Suvenmotiivid only contains three movements, but continues the harmonic and rhythmic complexity of Sügismaastikud. The first movement, Põualim, immediately begins on a tritone with octatonic scale. Different meters occur simultaneously during the second movement, which also moves quickly through 4 keys. The final movement ends with orchestral voicing and a 10-note chord cluster. Kevadkillud contains six very short movements, most of which are pandiatonic like Sügismaastikud. There is far less chromaticism and harmonic complexity than the middle two cycles, almost as if Tormis is bringing the set full circle. Moreover, the final movement of this cycle (and the entire set) is really just one major chord with embellishments. As a set, Loodispuldid represents a thorough perspective of Tormis’ mature style. The analyses done as a part of this paper reveal an incredible efficiency in his writing. Motives have purpose and context. Each movement possesses a well-defined harmonic language and rhythmic identity. A variety of formal structures exist, from binary to rondo. Even the many through-composed movements are expertly crafted with clear direction.

This study models the human process of music cognition on the digital computer. The definition of music cognition is derived from the work in music cognition done by the researchers Carol Krumhansl and Edward Kessler, and by Mari Jones, as well as from the music theories of Heinrich Schenker. The computer implementation functions in three stages. First, it translates a musical "performance" in the form of MIDI (Musical Instrument Digital Interface) messages into LISP structures. Second, the various parameters of the performance are examined separately a la Jones's joint accent structure, quantified according to psychological findings, and adjusted to a common scale. The findings of Krumhansl and Kessler are used to evaluate the consonance of each note with respect to the key of the piece and with respect to the immediately sounding harmony. This process yields a multidimensional set of points, each of which is a cognitive evaluation of a single musical event within the context of the piece of music within which it occurred. This set of points forms a metric space in multi-dimensional Euclidean space. The third phase of the analysis maps the set of points into a topology-preserving data structure for a Schenkerian-like middleground structural analysis. This process yields a hierarchical stratification of all the musical events (notes) in a piece of music. It has been applied to several pieces of music with surprising results. In each case, the analysis obtained very closely resembles a structural analysis which would be supplied by a human theorist. The results obtained invite us to take another look at the representation of knowledge and perception from another perspective, that of a set of points in a topological space, and to ask if such a representation might not be useful in other domains. It also leads us to ask if such a representation might not be useful in combination with the more traditional rule-based representations by helping to eliminate unwanted levels of detail in a cognitive-perceptual system.

This examination of Ralph Vaughan Williams' song cycle to poetry of Alfred Edward Housman, "On Wenlock Edge," will follow primarily two avenues of approach. First, following a brief biographical sketch of Vaughan Williams' career prior to the composition of "On Wenlock Edge," will be a discussion of Vaughan Williams' and Housman's respective aesthetic philosophies. In order to lay the background for certain salient characteristics of this cycle, parallels as well as differences in their artistic thinking will be explained. Secondly, a poetic analysis will precede the musical analysis of each song in order to differentiate between the original intent of the poet and the interpretation of the poetry by Vaughan Williams.

The purpose of this study is to examine the songs Tre Sonetti del Petrarca by Ildebrando Pizzetti. Effort is made to provide the performer with musical and poetic analyses to aid him in the preparation and interpretation of the songs. A consideration of the development of Italian solo song from 1822 to 1950 and brief biographical sketches of both the composer and the author of the text are included as background material. It is assumed that a detailed examination of the music and poetry will lead to a more meaningful expression in performance.

Jarmil Burghauser is mostly known as the editor of the complete critical edition of Antonín Dvořák's work. In addition to that he issued editions of Smetana, Fibich or Janáček. He also instrumented many pieces of these composers. Even though the sources refer to his fruitful activities in the field of composing, Burghauser as a composer is not very known. The aim of this thesis is to introduce Jarmil Burghauser as a composer of chamber music for brass instruments through the analysis of selected compositions. The objective is also to put Burghauser in the context of Czech musical work in the 20th century.

Orientador: Florivaldo Menezes Filho / Banca: Silvio Ferraz / Banca: Lia Tomás / Resumo: A obra de Karlheinz Stockhausen (1928-2007) é contornada por uma série de questões que concernem tanto ao âmbito das especulações próprias do fenômeno musical, quanto àquelas que permeiam este discurso. Dentre estas está a relação entre os procedimentos composicionais seriais, tal como ocorre nas primeiras obras, e outros situados em um âmbito mais alargado de possibilidades, onde os primeiros preceitos são remodelados e estendidos. Sob estas asserções proponho diálogos que versem sobre os vários desdobramentos da organização do discurso musical de sua música eletrônica. Como exemplo utilizo sobretudo Gesang der Jünglinge (1955- 1956) e Hymnen (1966-1967), mas também perfaço algumas incursões em sua obra instrumental e em seus primeiros estudos eletrônicos. Desta forma busco auxílios para uma melhor compreensão dos procedimentos composicionais que percorrem seu labor entre os anos de 1950 e 1966, sob o viés compositivo e auditivo. / Abstract: The work of Karlheinz Stockhausen (1928-2007) is contoured by several approaches that concern the range of the explorations of the very musical phenomena, and some others that permeate the musical discourse. Among them there is the relation between the serial procedures, as in the early works, and the procedures within a wider range of possibilities, where the first concepts are reviewed and extended. On these assertions, I propose a dialog that verse on the several implications on the organization of musical discourse in Stockhausen's electronic music. I use Gesang der Jünglinge (1955-1956) and Hymnen (1966-1967) as main examples, but all the same I do some incursions in his instrumental works, as so as in his electronic studies. Thus I search for subsidies to a better understanding of the compositional procedures used along 1950 and 1966, through the compositional and aural aspects. / Mestre
