Extracting Expressive Performance Information from Recorded Music
نویسندگان
چکیده
A computer system is described which performs polyphonic transcription of known solo piano music by using high-level musical information to guide a signal-processing system. This process, which we term expressive performance extraction, maps a digital audio representation of a musical performance to a MIDI representation of the same performance using the score of the music as a guide. Analysis of the accuracy of the system is presented, and its usefulness both as a tool for music-psychology researchers and as an example of a musical-knowledge-based signal-processing system is discussed.

Towards Automated Extraction of Tempo Parameters from Expressive Music Recordings
A performance of a piece of music heavily depends on the musician’s or conductor’s individual vision and personal interpretation of the given musical score. As basis for the analysis of artistic idiosyncrasies, one requires accurate annotations that reveal the exact timing and intensity of the various note events occurring in the performances. In the case of audio recordings, this annotation is...
متن کاملExtracting Expressive Tempo Curves from Music Recordings
Musicians give a piece of music their personal touch by continuously varying tempo, dynamics, and articulation. Instead of playing mechanically they speed up at some places and slow down at others in order to shape the piece of music. Similarly, they continuously change the sound intensity and stress certain notes. The automated analysis of different interpretations, also referred to as perform...
متن کاملEquipping Artificial Guitar Players with Biomechanical Constrains: a Case Study of Precision and Speed
Electronic means for generating music are often criticized for their “non-human” feeling. Models of expressive music performance have been used to alleviate this limitation by recreating human patterns found in music performance. These patterns are the outcome of both cognitive and biomechanical constrains. This paper focuses on the latter. We are interested in extracting biomechanical informat...
متن کاملA Dynamic Programming Approach to the Extraction of Phrase Boundaries from Tempo Variations in Expressive Performances
We present an approach to phrase segmentation that starts with an expressive music performance. Previous research has shown that phrases are delineated by tempo speedups and slowdowns. We propose a dynamic programming algorithm for extracting phrases from tempo information. We test two hypotheses for modeling phrase tempo shapes: a quadratic model, and a spline curve. We test the two models on ...
متن کاملExpressive timing analysis in classical piano performance by mathematical model selection
Given a piece of music, the timing of each beat varies from performer to performer. The study of these small differences is known as expressive timing analysis. Research into expressive timing helps us to understand human perception of music and the production of enjoyable music. Classical piano music is one music style where it is possible to measure expressive timing and hence provides a prom...
