    Real-time Composition in Elody

    Get PDF
    International audienceElody was initially an environment for musical composition allowing the description and algorithmic manipulation of non real-time musical structures. To allow the definition of real-time transformation processes, we have added a new primitive in the language : the real-time input stream. This object can be manipulated and transformed like non real-time objects even before being known. Evaluating a real-time expression gives as result a command sequence which drives a transformation engine. This one transforms a real-time input stream in an output stream

    Elody : a Java+MidiShare based Music Composition Environment

    International audienceThis paper introduces Elody, a MidiShare compatible music composition environment developed in Java. The heart of Elody is a visual functional language derived from the G-Calculus. The languages expressions are handled through visual constructors and Drag and Drop actions allowing the user to play in realtime with the language

    Content-based retrieval of melodies using artificial neural networks

    Human listeners are capable of spontaneously organizing and remembering a continuous stream of musical notes. A listener automatically segments a melody into phrases, from which an entire melody may be learnt and later recognized. This ability makes human listeners ideal for the task of retrieving melodies by content. This research introduces two neural networks, known as SONNETMAP and _ReTREEve, which attempt to model this behaviour. SONNET-MAP functions as a melody segmenter, whereas ReTREEve is specialized towards content-based retrieval (CBR). Typically, CBR systems represent melodies as strings of symbols drawn from a finite alphabet, thereby reducing the retrieval process to the task of approximate string matching. SONNET-MAP and ReTREEwe, which are derived from Nigrin’s SONNET architecture, offer a novel approach to these traditional systems, and indeed CBR in general. Based on melodic grouping cues, SONNETMAP segments a melody into phrases. Parallel SONNET modules form independent, sub-symbolic representations of the pitch and rhythm dimensions of each phrase. These representations are then bound using associative maps, forming a two-dimensional representation of each phrase. This organizational scheme enables SONNET-MAP to segment melodies into phrases using both the pitch and rhythm features of each melody. The boundary points formed by these melodic phrase segments are then utilized to populate the iieTREEve network. ReTREEw is organized in the same parallel fashion as SONNET-MAP. However, in addition, melodic phrases are aggregated by an additional layer; thus forming a two-dimensional, hierarchical memory structure of each entire melody. Melody retrieval is accomplished by matching input queries, whether perfect (for example, a fragment from the original melody) or imperfect (for example, a fragment derived from humming), against learned phrases and phrase sequence templates. Using a sample of fifty melodies composed by The Beatles , results show th a t the use of both pitch and rhythm during the retrieval process significantly improves retrieval results over networks that only use either pitch o r rhythm. Additionally, queries that are aligned along phrase boundaries are retrieved using significantly fewer notes than those that are not, thus indicating the importance of a human-based approach to melody segmentation. Moreover, depending on query degradation, different melodic features prove more adept at retrieval than others. The experiments presented in this thesis represent the largest empirical test of SONNET-based networks ever performed. As far as we are aware, the combined SONNET-MAP and -ReTREEue networks constitute the first self-organizing CBR system capable of automatic segmentation and retrieval of melodies using various features of pitch and rhythm

    Towards analytical synthesis: folk idioms, motivic integration and symmetry in B61a Bartok’s Concerto for Orchestra (1943)

    Get PDF
    The Hungarian composer Bela Bartok (1881-1945), unquestionably the twentieth-century’s most authoritative collector and analyst of Eastern European, Asian and Balkan folk music, composed the Concerto for Orchestra (1943) near the end of his career.1 His output was consistently marked by a stylistic synthesis of Western art music and the folk music of Eastern Europe, along with techniques of his own invention, often incorporating musical geometry. He also turned to styles such as neo-Classicism (or more specifically, neo-Baroque) and Primitivism, which, in common with Stravinsky, he explored along with the compositional technique of bitonality. Bartok pioneered the technique of polymodal chromaticism, using diverse modes derived from art music and folk music simultaneously. His use of dissonance never extended to atonality, as his chromatic compositions retained a fundamental pitch, and from the 1930s his compositional style became more tonal

    Film music and film genre

    This thesis explores the role that film genre plays in the construction of, predominantly, Hollywood movie scores. It begins with the simple assumption that each genre has its own set of musical conventions, its signature "paradigm", with the result that Westerns sound different from Horror films, which sound different from Romantic Melodramas and so on. It demonstrates that while this is broadly speaking so, the true picture is more complex, the essentially hybrid nature of most Hollywood films on a narrative level resulting in scores that are similarly hybrid in nature. To begin with, the various functions of film music are described, and that of generic location is isolated as being of key importance. The concept of film genre is then discussed, with particular reference to the notion of hybridity. The substance and sources of the musical paradigms of the Western, Horror film and Romantic Melodrama are described in depth; specific aspects of the War Film, Gangster, Thriller and Action paradigms are addressed more briefly. The thesis concludes with a cue by cue analysis of John Barry's score for Dances with Wolves (1990), demonstrating that while the dominant paradigm the music draws on is indeed that of the Western, the score also incorporates elements from a variety of other generic paradigms, shifts in musical emphasis that are dictated by the changing requirements of the narrative. Film music is shown to be profoundly influenced by film genre, but that the use of generically specific music is as complex and nuanced as cinema's negotiation of genre at narrative level. While genres do indeed have signature musical paradigms, these do not exist discretely, but in constant tension with and relation to one another

    Les logiciels d'aide à la composition musicale

    Get PDF
    Le XXème siècle aura vu le champ d'action du domaine musical prodigieusement élargi, à la fois par l'apparition de nouveaux moyens techniques de production du son, que par l'apparition de nouveaux modes d'investigation de la pensée musicale. Celle-ci s'affranchit des procédés classiques de composition pour explorer une grande variété et une grande richesse de modèles de pensée qui naissent notamment de la confrontation et de l'échange avec des domaines scientifiques eux aussi en pleine mutation. C'est à la fin des années 50 que naîtra l'informatique musicale. Cette discipline créera progressivement des outils qui vont s'inscrire en prolongement de ces évolutions, mais vont surtout leur ouvrir des perspectives beaucoup plus vastes tout en modifiant radicalement les moyens d'action de la pensée musicale. Ce sont ces nouveaux outils, le contexte de leur apparition ainsi que leur lien avec la pensée musicale qui sont présentés avec un point de vue particulier sur les langages formels pour l'écriture musicale

    Last Snow: An Analysis of an Original Electronic Music Suite

    Get PDF
    Last Snow is a suite of compositions in a genre that most closely approximates a contemporary jazz style with electronic elements and shifting meters. While there are clear examples of imitative synthesis within the work, many abstract examples of a more diffuse, impressionistic bent are also discernible. Much of the programming for these last mentioned tonal colors and synthesizer leads was accomplished by the composer. The suite has as a unifying feature the tones of the natural scale beginning from various alternate root pitches. The compositions, therefore, operate for the composer as something of a study with several challenges unique to each of the four resulting scales. There is a desire to more fully incorporate some concepts regarding synthetic chromaticism that the composer was considering during a month while he was convalescing in a hospital after a near fatal heart attack that was endured during the summer of 2009
