Analysis of Music Representations of Vocal Performance Based on Spectrogram

Spectrogram is a main analysis method of audio signals and other similar quasi - stationary ones and produces a time-frequency portrait of a signal. This paper researches correspondence between important time-frequency structures and music representations of vocal performance, aiming at providing quantitative analysis and objective information description of the subjective perception of specific voice techniques. Experiments and vocal music examples reveal and indicate that spectrogram is a powerful tool for aiding the study, comprehension, and interpretation of musical expression.
