Computer Accompaniment and Music Understanding1
نویسنده
چکیده
Music Understanding is the recognition or identification of structure and pattern in musical information. Five music understanding projects are discussed. In the first, Computer Accompaniment of Melodic Instruments, the goal is for a computer system to listen to and play along with a live performer, using a predetermined score. In the second project, the technique is extended to handle polyphonic keyboard input so that a computer can accompany a pianist. In the third project, accompaniment is extended to a situation, a blues improvisation, where the score is not known in advance, so an understanding of deeper musical structures is required. The fourth project, Beat Tracking, attempts to identify musical beats in a live performance without a score. The tempo and a transcription of the performance are by-products of Beat Tracking. The final project is the Piano Tutor, a computer-based intelligent teaching system.

Computer Coordination With Popular Music: A New Research Agenda
Computer accompaniment is now a well-established field of study, but nearly all work in this area assumes a Western classical music tradition in which timing is considered a flexible framework that performers manipulate for expression. This has important implications for the music, accompaniment, and performance style, and therefore the fundamental design of automatic accompaniment systems. Pop...
متن کاملCan the Computer Learn to Play Music Expressively?
A computer system is described that provides a real-time musical accompaniment for a live soloist in a piece of non-improvised music. A Bayesian belief network is developed that represents the joint distribution on the times at which the solo and accompaniment notes are played as well as many hidden variables. The network models several important sources of information including the information...
متن کاملUsing Computer Accompaniment to Assist Networked Music Performance
This paper proposes a novel scheme for audio communication in synchronous musical performances carried out over computer networks. The proposed scheme uses techniques inspired from computer accompaniment systems, in which a software agent follows the performance of a human musician in real-time, by synchronizing a pre-recorded musical accompaniment to the live performance. In networked settings...
متن کاملExpressive Humanoid Robot for Automatic Accompaniment
We present a music-robotic system capable of performing an accompaniment for a musician and reacting to human performance with gestural and facial expression in real time. This work can be seen as a marriage between social robotics and computer accompaniment systems in order to create more musical, interactive, and engaging performances between humans and machines. We also conduct subjective ev...
متن کاملMusic Plus One and Machine Learning
A system for musical accompaniment is presented in which a computer-driven orchestra follows and learns from a soloist in a concerto-like setting. The system is decomposed into three modules: the first computes a real-time score match using a hidden Markov model; the second generates the output audio by phase-vocoding a preexisting audio recording; the third provides a link between these two, b...
