A listener is thought to be able to organise musical notes into groups within musical streams/voices. A stream segment is a relatively short coherent sequence of tones that is separated horizontally from co-sounding streams and, vertically from neighbouring musical sequences. This paper presents a novel algorithm that discovers musical stream segments in symbolic musical data. The proposed algo...

Many computational models for processing music fail to capture essential aspects of the high-level musical structure and context, and this limits their usefulness, particularly for musically informed users. In this talk I describe two recent approaches to modelling musical harmony which attempt to reduce the gap between computational models and human understanding of music. The first is a chord...

We have created a system that identifies musical keywords or themes. The system searches for all patterns composed of melodic (intervallic for our purposes) repetition in a piece. This process generally uncovers a large number of patterns, many of which are either uninteresting or only superficially important. Filters reduce the number or prevalence, or both, of such patterns. Patterns are then...

Many approaches to analyzing the structure of a musical recording involve detecting sequential patterns within a selfsimilarity matrix derived from time-series features. Such patterns ideally capture repeated sequences, which then form the building blocks of large-scale structure. In this work, techniques from spectral graph theory are applied to analyze repeated patterns in musical recordings....

In this paper we explore how we compose sound for an interactive tangible and mobile interface, where the goal is to improve health and well-being for families with children with disabilities. We describe the composition process of how we decompose a linear beat-based and vocal sound material and recompose it with real-time audio synthesis and composition rules into interactive Scenes. Scenes t...

Memory, repetition, and anticipatory structure are considered important characteristics of musical style. Both composers and listeners often refer to these parameters in describing the music. In this work we conducted audio analyses in an attempt to determine correlations between audio features and human responses of Familiarity and Emotional Force. The analyses were performed on two recordings...

In this paper we present a music composition system that uses a corpus-based multi-objective evolutionary algorithm. We model the composition process using a Turing-complete virtual register machine to render musical models. These are evaluated using a series of fitness tests, which judge the statistical similarity of the model against a corpus of real music. We demonstrate that the methodology...

This study was conducted to identify and classify the lichens; determine the diversity index and richness of lichens. A total of 36 species belonging to six genera under three families was identified. Lichen species were mostly found at moderate high altitudinal range with an elevation of 1,131 meters above sea level and open areas where they received adequate sunlight with high moisture and hu...

biological diversity and species richness have been declined throughout the world as a result of human activities. measuring species richness is important in rangeland conservation to evaluate the status and trends of native plant species, detecting non-native species invasion and monitoring rare species. however, heterogeneity in plant distribution makes inventories difficult. in this study tw...
