[A] New tonal world: The Bohlen-Pierce Scale

Advocat, Amy January 2010 (has links)
This paper compares the Bohlen-Pierce scale to other octave and nonoctave-based tuning systems, drawing parallels between it and the widely used 12-equal temperament. These parallels lead to the hypothesis that there can be a set ofharmonic mIes applicable to the Bohlen-Pierce scale that are analogous to the CUITent musical practice. Those theorized mIes are then applied to some examples of the growing body of musical compositions wrtten in the BohlenPierce scale. Aiso included are supportive arguments for a preference of the use of odd-partial timbres in performance of this scale, which make the invention of the Bohlen-Pierce clarinet a major tuming point in the scale's development. Sorne of the musical works studied were written specifically for this author's performance on the Bohlen-Pierce clarinet. / Ce document compare la gamme Bohlen-Pierce d'autres systmes d'accord octave et non-octave-bass, tablissant des parallles entre soi et le systme la plus utilis, temprament de I2-gal. Ces parallles mnent la possibilit qu'il peut tre des rgles harmoniques applicables la gamme BohlenPierce qui sont analogues la pratique musicale courante. Ces rgles thorises sont alors appliques quelques exemples du corps croissant de compositions musicales crites la gamme Bohlen-Pierce. Il-y-a aussi inclus des arguments qui support la prfrence d'utilisation des timbres impair-partiels dans la performance de cette gamme, qui ferait l'invention de la clarinette Bohlen-Pierce un point tournant majeur dans la dveloppement de cette gamme.

A practical approach to the study of sound for musicians

Beardsley, Robert Lyle 01 January 1946 (has links)
This account of the beginning of music might equally well be applied to man's discovery of sounds produced by the stretched string on his hunting-bow, or skins stretched across wooden frames. Pure fancy though it may be, the account serves to illustrate the dependence of music on the universal principles of science. Sound, the medium of expression, the vehicle, of music, is purely physical phenomenon. All aspects of its production, its transmission, and its ultimate reception are based invariable on physical laws. All musical instruments operate under these laws, as do the tones and combinations of tones which the instruments produce. Since that time when our prehistoric man made his discoveries, all musicians have had to depend upon scientific principles in producing the various sounds with which they work In order to deal most effectively with these tones, it is necessary that the musician understand some of the principles governing their production and their various relationships. It is with this necessity in mind that this thesis is being written. In the thesis an attempt is made to present those physical aspects of sound which will be of the most practical use to the musician and which will give him a better understanding of the materials with which he works. As often as it is possible and practical, direct illustration of the applications to the musician's work of the principles discussed are given. this thesis is not intended to be a study of sound. The subject is covered thoroughly in a number of text-books. lt is rather an attempt to show how the Science of Sound is related to the Art of Music, to demonstrate in what ways the latter is dependent upon the former, and to outline an approach to a study of the physical principles of sound for the musician.

An integrated system for dynamic control of auditory perspective in a multichannel sound field /

Corey, Jason Andrew January 2002 (has links)
An integrated system providing dynamic control of sound source azimuth, distance and proximity to a room boundary within a simulated acoustic space is proposed for use in multichannel music and film sound production. The system has been investigated, implemented, and psychoacoustically tested within the ITU-R BS.775 recommended five-channel (3/2) loudspeaker layout. The work brings together physical and perceptual models of room simulation to allow dynamic placement of virtual sound sources at any location of a simulated space within the horizontal plane. / The control system incorporates a number of modules including simulated room modes, "fuzzy" sources, and tracking early reflections, whose parameters are dynamically changed according to sound source location within the simulated space. The control functions of the basic elements, derived from theories of perception of a source in a real room, have been carefully tuned to provide efficient, effective, and intuitive control of a sound source's perceived location. / Seven formal listening tests were conducted to evaluate the effectiveness of the algorithm design choices. The tests evaluated: (1) loudness calibration of multichannel sound images; (2) the effectiveness of distance control; (3) the resolution of distance control provided by the system; (4) the effectiveness of the proposed system when compared to a commercially available multichannel room simulation system in terms of control of source distance and proximity to a room boundary; (5) the role of tracking early reflection patterns on the perception of sound source distance; (6) the role of tracking early reflection patterns on the perception of lateral phantom images. / The listening tests confirm the effectiveness of the system for control of perceived sound source distance, proximity to room boundaries, and azimuth, through fine, dynamic adjustment of parameters according to source location. All of the parameters are grouped and controlled together to create a perceptually strong impression of source location and movement within a simulated space.

Within echoic chambers : for small orchestra and tape

Bianchi, Frederick January 1982 (has links)
WITHIN ECHOIC CHAMBERS: for small orchestra and tape is based on the integration of 3 major concepts: 1) Structural 2) Psychological 3) Technical. These individual concepts represent areas in which the composer has concentrated the majority of his research over the last 2 years. It is the incorporation of these concepts which form the basis of the creative project.Through the application of arc acoustical design, the entire work is given thematic and structural unity. This acoustical design is based or the onset, steady state and decay characteristics of complex tones and is incorporated into the work as a compositional tool from which a number of musical dimensions are controlled. Since the onset, steady state and decay characteristics of complex tones determine the way we perceive sound, it acts both as a common link between the 3 concepts and the entire structural basis of the creative project. Used in this way the acoustical design became a catalyst from which musical sound structures crystallized as opposed to being a mere theoretical algorithm for autonomous music composition. / School of Music

Musical vibrotactile feedback

Birnbaum, David M. January 2007 (has links)
This thesis discusses the prospect of integrating vibrotactile feedback into digital musical instruments. A holistic approach is taken, considering the role of new instruments in electronic music, as well as the concept of touch in culture and experience. Research about the human biological systems that enable vibrotactile perception is reviewed, with a special focus on its relevance to music. Out of this review, an approach to vibration synthesis is developed that integrates the current understanding of human vibrotactile perception. An account of musical vibrotactile interaction design is presented, which includes the implementation of a vibrotactile feedback synthesizer and the construction of two hardware prototypes that display musical vibration.

An evaluation of the efficacy of digital real-time noise control techniques in evoking the musical effect

Warneke, Andrew Travis January 2012 (has links)
This study sought to determine whether or not it may be possible to evoke ‘the musical effect' – the emotional response perceived by music listeners – using white noise as a sound-source and real-time digital signal processing techniques. This information was considered to be valuable as in a world driven by technological progress the potential use of new or different technologies in creating music could lead to the development of new methods of – and tools for – composition and performance. More specifically this research asked the question 'what is music?' and investigated how humans – both trained musicians and untrained people – perceive it. The elements of music were investigated for their affective strengths and new fields of research explored for insights into emotion identification in music. Thereafter the focus shifted into the realm of Digital Signal Processing. Common operations and techniques for signal manipulation were investigated and an understanding of the field as a whole was sought. The culmination of these two separate, yet related, investigations was the design and implementation of a listening experiment conducted on adult subjects. They were asked to listen to various manipulated noise-signals and answer a questionnaire with regard to their perceptions of the audio material. The data from the listening experiment suggest that certain DSP techniques can evoke ‘the musical effect’. Various musical elements were represented via digital techniques and in many cases respondents reported perceptions which suggest that some effect was felt. The techniques implemented and musical elements represented were discussed, and possible applications for these techniques, both musical and non-musical, were explored. Areas for further research were discussed and include the implementation of even more DSP techniques, and also into garnering a more specific idea of the emotion perceived by respondents in response to the experiment material.
