An experiment for the automatic detection of expressive- ness in music performances using a perceptive based audi- tory models is presented. We recognize the intentions with reference to the Kinematics Energy expressive space. Au- dio features have been firstly extracted using a perception- based analysis, then we have made several analyses on timing and spectral features over overlapping sliding win- dows, estimating average and variance for each one of the features. Using a naive Bayesian classifier we investigated which features are most relevant for expression detection. This experiment also yielded interesting contributions for tuning the Kinematics Energy space with new features.

Abstract
An experiment for the automatic detection of expressive- ness in music performances using a perceptive based audi- tory models is presented. We recognize the intentions with reference to the Kinematics Energy expressive space. Au- dio features have been firstly extracted using a perception- based analysis, then we have made several analyses on timing and spectral features over overlapping sliding win- dows, estimating average and variance for each one of the features. Using a naive Bayesian classifier we investigated which features are most relevant for expression detection. This experiment also yielded interesting contributions for tuning the Kinematics Energy space with new features.Pubblicazioni consigliate
