Nevertheless, this improvisation is at a single scale (by default based on events corresponding to the corpus segmentation), and the addition of a multi-scale segmentation would reinforce the overall form and struc- ture of the improvisation. We propose to use MORFOS, a music analysis software based on cognitive musicology that offers real-time analysis of audio or symbolic musical works. It produces a multi-level representation, called <em>multi-scale formal diagram<\/em>, which represents the\u00a0<em>organisation<\/em>,\u00a0<em>form\u00a0<\/em>and\u00a0<em>structure\u00a0<\/em>of the musical piece. We thus introduce the notion of\u00a0<em>Dynamic Corpus Shaping<\/em>. This approach modifies the internal structure of the corpus in real time to better align with the intentions of the artist interacting with Somax2, taking advantage of the hierarchical segmentation provided by MORFOS. To achieve this, we added the notion of\u00a0<em>behaviours\u00a0<\/em>to Somax2, as well as a\u00a0<em>queue\u00a0<\/em>enabling new scenarios to be created from the corpus analyzed by MORFOS. First, we will analyse L.V. Beethoven\u2019s\u00a0<em>Bagatelle in A minor Op. 119\u00a0<\/em>with MORFOS, then we present new scenarios based on this corpus.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Article by Jos\u00e9phine Calandra, Marco Fiorini and G\u00e9rard Assayag has been accepted for the Journ\u00e9es de l&rsquo;Informatique Musicale (JIM2025) in Lyon, France.
