The Performance Worm: Real Time Visualisation of Expression based on Langner's Tempo-Loudness Animation
نویسندگان
چکیده
In an expressive performance, a skilled musician shapes the music by continuously modulating aspects like tempo and loudness to communicate high level information such as musical structure and emotion. Although automatic modelling of this phenomenon remains beyond the current state of the art, we present a system that is able to measure tempo and dynamics of a musical performance and to track their development over time. The system accepts raw audio input, tracks tempo and dynamics changes in real time, and displays the development of these expressive parameters in an intuitive and aesthetically appealing graphical format which provides insight into the expressive patterns applied by skilled artists.

The "Air Worm": an Interface for Real-Time manipulation of Expressive Music Performance
Expressive performance of traditional Western music is a complex phenomenon which is mastered by few, and yet appreciated by many. In this paper we explore various ways of interacting with expressive performances using methods that are accessible to non-expert music-lovers. The key idea is that a non-expert cannot control the vast range of parameters which musicians use to create expression; th...
متن کاملReal Time Tracking and Visualisation of Musical Expression
Skilled musicians are able to shape a given piece of music (by continuously modulating aspects like tempo, loudness, etc.) to communicate high level information such as musical structure and emotion. This activity is commonly referred to as expressive music performance. The present paper presents another step towards the automatic high-level analysis of this elusive phenomenon with AI methods. ...

Automatic analysis of digital audio with musical content is a difficult — but important — task for various applications in computer music, audio compression, and music information retrieval. This chapter contains a brief review of audio analysis as it relates to music, followed by three case studies of recently developed systems which analyse specific aspects of music. The first system is BeatR...
متن کاملOn the analysis of musical expression in audio signals
In western art music, composers communicate their work to performers via a standard notation which specificies the musical pitches and relative timings of notes. This notation may also include some higher level information such as variations in the dynamics, tempo and timing. Famous performers are characterised by their expressive interpretation, the ability to convey structural and emotive inf...
متن کاملReal-time Visualisation of Loudness along Different Time Scales
We propose a set of design criteria for visualising loudness features of an audio signal, measured along different time scales. A novel real-time loudness meter, based on these criteria, is presented. The meter simultaneously shows short-term loudness, long-term loudness and peak level. The short-term loudness is displayed using a circular bar graph. The meter displays the longterm loudness by ...
