Tre musikinstrument – En röst. En studie om omställningsprocessen mellan ett träblåsinstrument till ett annat. Detta område omfattar tvärflöjt- oboe- och altsaxofonspel. Arbetet bygger på observationer av en sex veckor lång instuderingsprocess, sett i relation till ett urval av tidigare forskning och högskoleuppsatser inom området. Studien har i syfte att utforska omställningsprocessen när jag byter från det ena blåsinstrumentet till det andra. Detta för att ge en djupare inblick i en multiinstrumentalists vardag och belysa de fenomen som ligger till grund för spelet för respektive instrument och som sedan tas med i omställningsprocessen. Denna kvalitativa studie utgår från ett livsvärldsperspektiv och metod är loggboksskrivande samt videodokumentation. Resultatet bärs upp av två teman: Inre röst och instrumentbyte-muskelbyte som står för mentala respektive fysiska handlingar. Efter resultatet följer en diskussion som sätts i förhållande till litteratur och tidigare forskning inom området. Arbetet avslutas med tankar om dess betydelse samt möjligheter till framtida forskning. / Three musical instruments – One voice. A study of the conversion process between a woodwind instrument to another. This area includes the flute, oboe and the alto saxophone. This study is based on observations of a six-week rehearsal process in relation to a sample of previous research and academic papers in the field. The study is aimed to explore the conversion process when I switch from one wind instrument to the other. This is to provide a deeper insight into a multiinstrumentalists everyday life and highlight all the phenomena that form the basis of the play for each instrument and then be included in the conversion process. This qualitative study is based on a life-world perspective and method logbook writing and video documentation. The result is supported by two themes: Inner voice and change of instrument-muscle change representing mental and physical actions. After the result is a discussion that is related to the literature and previous research in the area. The work concludes with thoughts about its importance as well as opportunities for future research.

This thesis focuses on the topic of piano accompaniment, which is an essential and beautiful part of piano playing. This field demands from the pianist a specific approach, which is a subject and core of many study programmes throughout the world. The aim of the first part of this thesis is to map the evolution as well as the current state of knowledge in the field of piano accompaniment using scientific literature on the subject as well as curricula of study programmes obtained from universities in central Europe, where piano accompaniment is taught as a major study course. A strong correlation has been established based on this research between theory in scientific literature on the subject and the current practice of piano accompaniment education in central Europe. The aim of the second part of this thesis is to expand further the level of knowledge in scientific literature, which is insufficient mainly in the accompaniment of solo musical instruments. For this reason, the second part of the thesis focuses on the specific problems in piano accompaniment of musical instrument groups, i.e. string instruments, woodwind instruments and brass instruments. For these three groups case studies have been created, which examine the specific characteristics of the musical instruments in relation to piano...

This is a study where I examine and compare the perceived emotional expression of brass instruments and reed instruments to investigate whether one group have an inherent tendency to better express a certain emotion than the other group. Based on scientifically proven methods, I have composed two musical pieces, where one of them represents the emotion of happiness and the other one represents the emotion of sadness. I have then written 5 arrangements per musical piece, where one of them consists of piano, two consists of solo instruments from each instrument group accompanied by piano, and two consists of a trio from each instrument group. This makes a total of 10 arrangements. These arrangements serve as audio examples in a web survey where I compare the two instrument groups based on how the audience perceive their emotional expression. A total of 36 people participated in the survey. Regarding the emotion of happiness, 71 % of the participants felt that trumpet and piano was the solo instrument version that best expressed happiness while 18 % chose oboe and piano. 44 % chose the brass trio as the happiest version while 36 % felt that the reed trio best expressed happiness. When it came to the emotion of sadness, 19 % of the participants chose trumpet and piano as the saddest solo instrument version, while 72 % felt that oboe and piano sounded the saddest. 25 % chose the brass trio as the saddest version while 67 % chose the reed trio.

Syncretisms is an original composition scored for flute, oboe, clarinet, horn, bassoon, and marimba (2-mallet minimum, 4 recommended) with an optional percussion part requiring glockenspiel and chimes, and has an approximate duration of 6 min. 45. sec. The composition combines modern western tuning, timbre, and harmonic language with organizational principles identified in music from Southeast Asia (including music from cultures found in Thailand, Cambodia, Malaysia, and Indonesia). The accompanying paper describes each of these organizational principles, drawing on the work of scholars who have performed fieldwork, and describes the way in which each principle was employed in Syncretisms. The conclusion speculates on a method for comparing musical organizational systems cross-culturally.

Opera fantasias have been denigrated as insufficiently intellectual or serious, as derivative, as merely popular or sentimental. However, many of the perceived flaws were, if not hallmarks, at least accepted realities of Italian opera composing. Like opera itself, the opera fantasia is a popular art form, stylistically predictable yet formally flexible, based heavily on past operatic tradition and prefabricated materials. I approach opera fantasias, instrumental works that use themes from a single opera as the body of their virtuosic and flamboyant material, both historically and theoretically, concentrating on compositions written for and by woodwind-instrument performers in Italy in the second half of the nineteenth century. Important overlapping strands in my theoretical framework include the concept of virtuosity and its gradual demonization, the strong gendered overtones of individual woodwind instruments and of virtuosity, the distinct Italian context of these fantasias, the presentation and alteration of opera narratives in opera fantasias, and the technical and social development of woodwind instruments. I have uncovered a large body of compositions and composers, many of whom have not been written about in English, through archival research in Milan, Naples, Parma, Bologna, and Palermo. This reveals trends in operas used for fantasias, temporally, spatially, and between instruments, as well as further trends in the use of specific melodies. I use contemporary reviews of performances and compositions to attest to the popularity of the opera fantasia throughout the second half of the nineteenth century in Italy, including oboist Antonio Pasculli as a case study. This often overlooked genre is intimately tied to the central canon and deeply connected to its social and musical contexts. Approaching the opera fantasia as a coherent and meaningful group of works clarifies a genre that has been consciously stifled and cultural resonances that still impact music reception and performance today.

The bassoon is a conical woodwind instrument blown with a double-reed mouthpiece. The sound is generated by the periodic oscillation of the mouthpiece which excites the air column. The fundamental frequency of this oscillation is determined to a large extent by the resonances of the air column. These can be varied by opening or closing tone-holes. For any given tone hole setting a fine-tuning in pitch is necessary during playing. Musicians adjust the slit opening of the double-reed by pressing their lips against the opposing reed blades. These so-called embouchure corrections are required to tune the pitch, loudness and sound color of single notes. They may be tedious, especially if successive notes require inverse corrections. However, such corrections are essential: Due to the very high frequency sensitivity of the human ear playing in tune is the paramount requirement when playing music. This implies, that embouchure actions provide an important insight into a subjective quality assessment of reed wind instruments from the viewpoint of the musician: An instrument requiring only small corrections will be comfortable to play. Theoretical investigations of the whole system of resonator, reed, and musician by use of a physical model nowadays still seem insufficient with respect to the required precision. Therefore the path of well-described artificial mouth measurements has been chosen here. For the separate treatment of the resonator and the double-reed, existing classical models have been used. Modifications to these models are suggested and verified experimentally. The influence of the musician is incorporated by the lip force-dependent initial reed slit height. For this investigation a measurement setup has been built that allows precise adjustment of lip force during playing. With measurements of the artificial mouth parameters blowing pressure, mouthpiece pressure, volume-flow rate and axial lip position on reed, the experiment is fully described for a given resonator setting represented by an input impedance curve. By use of the suggested empirical model the adjustment parameters can be turned into model parameters. A large data set from blowing experiments covering the full tonal and dynamical range on five modern German bassoons of different make is given and interpreted. The experimental data presented with this work can be a basis for extending the knowledge and understanding of the interaction of instrument, mouthpiece and player. On the one hand, they provide an objective insight into tuning aspects of the studied bassoons. On the other hand the experiments define working points of the coupled system by means of quasi-static model parameters. These may be useful to validate dynamical physical models in further studies. The experimental data provide an important prerequisite for scientific proposals of optimizations of the bassoon and other reed wind instruments. It can further serve as a fundament for the interdisciplinary communication between musicians, musical instrument makers and scientists.

Yvonne Desportes (1907-1993) was an influential female composer, teacher, and music theorist. Her early success as a recipient of the Prix de Rome for composition (1932) marked the beginning of her distinguished career in music culminating in a 35-year professorship at the Paris Conservatory. Despite the relative obscurity of her music, Desportes was a prolific composer and published numerous works for clarinet quartet. This dissertation seeks to promote the clarinet music of Yvonne Desportes through a pedagogical examination of her clarinet quartets. The equitable parts and quality of Desportes' compositional style allow her clarinet quartets to be effective teaching tools for the development of fundamental clarinet skills relating to tone, technique, and musical style.
