Virtual Conductor for String Quartet Practice

This paper presents a system that emulates an ensemble conductor for string quartets. This application has been developed as a support tool for individual and group practice, so that users of any age range can use it to further hone their skills, both for regular musicians and students alike. The virtual conductor designed can offer similar indications to those given by a real ensemble conductor to potential users regarding beat times, dynamics, etc. The application developed allows the user to rehearse his/her performance without the need of having an actual conductor present, and also gives access to additional tools to further support the learning/practice process, such as a tuner or a melody evaluator. The system developed also allows for both solo practice and group practice. A set of tests were conducted to check the usefulness of the application as a practice support tool. A group of musicians from the Chamber Orchestra of Malaga including an ensemble conductor tested the system, and reported to have found it a very useful tool within an educational environment and that it helps to address the lack of this kind of educational tools in a self-learning environment.This work has been funded by the Ministerio de Economia y Competitividad of the Spanish Government under Project No. TIN2010-21089-C03- 02 and Project No. IPT-2011-0885-430000 and by the Ministerio de Industria, Turismo y Comercio under Project No. TSI-090100-2011-25

Conducting a virtual ensemble with a kinect device

This paper presents a gesture-based interaction technique for the implementation of an orchestra conductor and a virtual ensemble, using a 3D camera-based sensor to capture user’s gestures. In particular, a human-computer interface has been developed to recognize conducting gestures using a Microsoft Kinect device. The system allows the conductor to control both the tempo in the piece played as well as the dynamics of each instrument set independently. In order to modify the tempo in the playback, a time-frequency processing-based algorithmis used. Finally, an experiment was conducted to assess user’s opinion of the system as well as experimentally confirm if the features in the system were effectively improving user experience or not.This work has been funded by the Ministerio de Economia y Competitividad of the Spanish Government under Project No. TIN2010-21089-C03-02 and Project No. IPT-2011-0885-430000 and by the Junta de Andalucia under Project No. P11-TIC-7154.

FROM A HUMBLE CRY TO A HOLY CHACONNE: THE BACKGROUND, ANALYSIS, AND PERFORMANCE GUIDE TO CHACONNE FOR TOKKAE, OP. 96 BY M. W. JOHANN KIM

The cries of animals have been used as motivic material in classical music literature throughout history. This project considers the Cambodian tocay gecko’s cry as the motif which embodies the harmonic structure in Chaconne for Tokkae for Violin and Piano, Op. 96 by Dr. Myung Whan Johann Kim. It reveals how Dr. Kim adapts unique compositional style and technique such as the bell harmony of Dr. Kurt Anton Hueber, to develop the theme into 39 colorful variations. The essential elements of the chaconne and the composer’s intentions are examined through personal interviews and correspondence with the composer. These elements are discussed along the biography of Dr. Kim, and introduction to Dr. Hueber’s bell harmony, as well as Dr. Kim’s religious beliefs of Christianity, which the composer deeply integrate with this chaconne. By offering rigorous analysis and performance guidance of Chaconne for Tokkae for Violin and Piano, Op. 96 which world premiered by violinist JuRang Kim and pianist Dr. Sanghee Kim on May 16, 2022, this paper enables performers to interpret this piece with the composer’s intentions and inspiration in mind and deliver a performance more precisely aligned with Dr. Johann Kim’s vision

Musical accompaniments in the preparation of marimba concerti: a survey of selective interactive music software programs

The purpose of this study was to investigate the features of three interactive music software programs and their application in preparing marimba concerti. Specifically, the study evaluated Finale, NOTION, and SmartMusic for their viability in preparing Concerto No. 1 in D Minor for Marimba and Orchestra by Noah Taylor. A review of the literature relating to interactive music software programs revealed a lack of studies examining the use of these types of programs in the preparation of marimba concerti. All three software programs were installed on a 15-inch MacBook Pro computer that met system requirements for all three programs. Documentation indicated that all three interactive music software programs offered viable alternatives to preparing marimba concerti with piano reductions. Finale and NOTION provided comparable instrument sounds in terms of quantity and quality. Finale improved its instrument sound quality and quantity through its integrated Garritan Instruments sound library. NOTION offered improved sound quality and quantity through the purchase of Sound Expansion Kits. Finale’s Tempo Tap feature and NOTION’s NTempo function provided real-time tempo adjustment and the Audio Mixer mechanism for both programs allowed the user to isolate instruments. SmartMusic offered comparable instrument realizations through its SoftSynth device. The program, however, did not offer a tempo control feature that was compatible with marimba. Also, SmartMusic’s export options and Practice Loop feature allowed the user to effectively isolate instruments. Further research recommendations included empirical studies examining the benefits of interactive music software programs on the preparation of marimba concerti and applying earlier studies performed on the Vivace interactive music software program to current music software programs. Descriptive study recommendations included investigating the applications of interactive music software in the preparation of orchestral percussion excerpts and marimba concertos with wind ensemble, percussion ensemble, or chamber ensemble accompaniments

Virtual orchestration: a film composer's creative practice

The advent of digital technologies has led to a major change in the process of film music composition; consequent developments in music technology have forced film composers to adapt to this change. Technological innovations such as digital audio workstations (DAWs) and virtual musical instruments have made possible the creation of virtual orchestras that are technologically capable of simulating the sound and behaviour of a traditional acoustic orchestra. This has had an effect on film music production and on the creative process of the professional film composer in a way that today, creating orchestral simulations or 'mock-ups' that imitate live orchestras (or smaller ensembles) has become a requirement in the film industry and thus an essential part of the film-scoring process. In the context of contemporary film music production, this thesis investigates how orchestral simulations are composed and created using computer music technology and virtual sample-based instruments. In asking 'how', the focus is on the film composer's activities and thought processes during this creative cycle, along with the nature of the interactive relationship between composer and music materials. This study aims to show the complexity of the film composer's creative practice and to advance understanding of how the use of computer music technology and orchestral sample libraries is influencing the compositional process and compositional outcome. To address these questions, a qualitative multiple case study methodology approach was chosen that included examination of the practice of seven professional film composers working in the field of feature film as the primary valid source of data. The exploration involved semi-structured interviews with composers, observations and analysis of their studio practice and inspection of their compositional tools. Taken as a whole, the evidence provided by this study is that the process of creating orchestral simulations is a process of film music composition during which professional film composers are creating orchestral sounds through the use of computers, digital sequencing, samplers and sample-based virtual acoustic instruments for the realisation of musical works. It is a process of using and manipulating recorded samples of real acoustic instruments to generate an expressive and convincing musical performance through sample-based orchestral simulation. A characteristic of this compositional practice is that it is a continuous process that proceeds in stages over time where all procedures can be applied repeatedly between stages. The process of creating orchestral simulations for the purpose of the film score is a multifaceted compositional activity involving a complex set of relationships among different compositional states of mind and compositional activities in which film composers experience music and interact with musical materials and media in various ways. This creative activity is a process involving a single person and a mixture of various compositional tools, the composer's skills and abilities brought into existence through a creative process that requires a thorough blend of art and craft to be demonstrated at all times

Reverberation perception in Spanish cathedrals

Listening tests based on paired comparisons have been employed to investigate the subjective perception of the acoustic environment in highly reverberant large spaces. Seven cathedrals in the southern half of Spain have been included in the survey, thereby covering a wide range of reverberation-time values from 4.32 s in Murcia cathedral to 8.96 s in Cadiz cathedral at mid-frequencies. These cathedrals present a common architectural typology, known as the "Spanish style", which allows similar source-receiver points to be selected when comparisons are made between two different cathedrals. The tests were carried out in the listening room of the Acoustics Laboratory of the Applied Physics II Department of the School of Architecture of the University of Seville. Several types of anechoic sound signals (choral pieces, extracts of Baroque instrumental music, and a speech) were auralised with the impulse responses measured in the cathedrals to be used in the tests. Such auralisations were reproduced through headphones, thereby ensuring that all audio signals were perceived at the same level during each test. The results indicated the existence of a threshold, whose value depends on the type of stimulus, from which the objective reverberation differences are subjectively remain almost indistinguishable to the listene
