Comper: towards a Model for Generating Compositions from Expressive Music performances
نویسندگان
چکیده
We introduce the concept of Expressive Performance Generated Composition where the initial specification for a composition comes from the details of an expressive performance. This expressive performance may have been of a previous piece or be specially produced for the composition. The expressive deviations in the performance are used to generate a meaningful interpretation of the performance through a new composition, by attempting to invert methodologies for simulating human expressive performance of music. The development of such systems is motivated by four elements: (1) The final composed piece will be immediately playable by computer in an expressive way without any need for complex structural analysis; (2) It provides methods for an innovative, but meaningfully specified, system for composition; (3) Research done into computer expressive performance can then be tested for application to algorithmic composition – for example emotional expression; (4) It may be easier for inexperienced composers/musicians to specify a composition by expressive performance elements.

A Learning Scheme for Generating Expressive Music Performances of Jazz Standards
We describe our approach for generating expressive music performances of monophonic Jazz melodies. It consists of three components: (a) a melodic transcription component which extracts a set of acoustic features from monophonic recordings, (b) a machine learning component which induces an expressive transformation model from the set of extracted acoustic features, and (c) a melody synthesis com...
متن کاملModeling Expressive Music Performance in Bassoon Audio Recordings
In this paper, we describe an approach to inducing an expressive music performance model from a set of audio recordings of XVIII century bassoon pieces. We use a melodic transcription system which extracts a set of acoustic features from the recordings producing a melodic representation of the expressive performance played by the musician. We apply a machine learning techniques to this represen...
متن کاملMulti-Agent Simulation for Generating Expressive Music Performance
This paper presents a system that implements a society of agent performers that evolve expressive music performances (EMP) through their interactions. Each agent performer evaluates a performance using a fitness function derived from the structure of the performing piece. Agents are born with different fitness functions, representing preferences for different types of performance. A new-born ag...
متن کاملModeling Embellishment, Timing and Energy Expressive Transformations in Jazz Guitar
Professional musicians manipulate sound properties such as timing, energy, pitch and timbre in order to add expression to their performances. However, there is little quantitative information about how and in which context this manipulation occurs. This is particularly true in Jazz music where learning to play expressively is mostly acquired intuitively. In this paper we describe a machine le...
متن کاملExpressive Performance in the Human Tenor Voice
This paper presents preliminary results on expressive performance in the human tenor voice. This work investigates how professional opera singers manipulate sound properties such as timing, amplitude, and pitch in order to produce expressive performances. We also consider the contribution of features of prosody in the artistic delivery of an operatic aria. Our approach is based on applying mach...
