Real-time Musical Accompaniment
نویسندگان
چکیده
The artificially intelligent computer performer is a software program that enables a computer to accompany, in real-time, live performers. The computer is, in effect, a participating member of a musical ensemble. It interacts with the musicians by listening to them and it makes musical decisions based on what it hears and what it Imows about music. The computer performer uses parallel processing to speed up its response time. The implementation of the system is discussed, the tracking algorithm and the subsequent computer response are described, and then ongoing and future work are outlined. Musical considerations which have influenced the development of the system are also discussed.

A Bayesian Network for Real-Time Musical Accompaniment
We describe a computer system that provides a real-time musical accompaniment for a live soloist in a piece of non-improvised music for soloist and accompaniment. A Bayesian network is developed that represents the joint distribution on the times at which the solo and accompaniment notes are played, relating the two parts through a layer of hidden variables. The network is first constructed usi...
متن کاملImprovasher: A Real-Time Mashup System for Live Musical Input
In this paper we present Improvasher a real-time musical accompaniment system which creates an automatic mashup to accompany live musical input. Improvasher is built around two music processing modules, the first, a performance following technique, makes beat-synchronous predictions of chroma features from a live musical input. The second, a music mashup system, determines the compatibility bet...
متن کاملOperational semantics of a domain specific language for real time musician-computer interaction
With the advent and availability of powerful personal computing, the computer music research and industry have been focusing on real-time musical interactions between musicians and computers; delegating human-like actions to computers who interact with a musical environment. One common use-case of this kind is Automatic Accompaniment where the system is comprised of a real-time machine listenin...
متن کاملIncremental Parsing for Real-time Accompaniment Systems
The incremental parsing (IP) algorithm has been successfully used in real-time applications, due to its efficiency and power to model musical style. For example, musical systems using IP can continue phrases played by a musician in a consistent way. This paper proposes some alterations in the original algorithm in order to adapt it to accompaniment systems.
متن کاملImproving and Adapting Finite State Transducer Methods for Musical Accompaniment
A common area of research within music technology is the automatic generation of musical accompaniment. Of particular interest is the generation of harmonic accompaniment to melody. While there are many approaches to solving this problem, the use of various types of finite state machines is popular. One such finite state machine, the finite state transducer (FST), has been used in a few accompa...
متن کاملBeat Tracking Towards Automatic Musical Accompaniment
In this paper we address the issue of causal rhythmic analysis, primarily towards predicting the locations of musical beats such that they are consistent with a musical audio input. This will be a key component required for a system capable of automatic accompaniment with a live musician. We are implementing our approach as part of the aubio real-time audio library. While performance for this c...
