Evaluation System for Groove Feelings Evoked by Drum Sounds

抄録

In this study, we define stochastic models for tight and loose groove feelings and propose an evaluation system for the groove feelings evoked by drum sounds. There are two main types of groove feelings, tight and loose, and they are known among professional musicians and music enthusiasts. These groove models are defined as a bivariate normal distribution with deviations for snare and bass drums as random variables. As an application of these models, we propose our evaluation system, in which a monaural, polyphonic drum set recordings is input and evaluations regarding tight and loose are output. We conducted an evaluation experiment and showed that this system correctly identifies tight and loose groove feelings.
