Exploring and Applying Audio-Based Sentiment Analysis in Music
Etash Jhanji
Sentiment analysis is a continuously explored area of text processing that
deals with the computational analysis of opinions, sentiments, and subjectivity
of text. However, this idea is not limited to text and speech, in fact, it
could be applied to other modalities. In reality, humans do not express
themselves in text as deeply as they do in music. The ability of a
computational model to interpret musical emotions is largely unexplored and
could have implications and uses in therapy and musical queuing. In this paper,
two individual tasks are addressed. This study seeks to (1) predict the emotion
of a musical clip over time and (2) determine the next emotion value after the
music in a time series to ensure seamless transitions. Utilizing data from the
Emotions in Music Database, which contains clips of songs selected from the
Free Music Archive annotated with levels of valence and arousal as reported on
Russel's circumplex model of affect by multiple volunteers, models are trained
for both tasks. Overall, the performance of these models reflected that they
were able to perform the tasks they were designed for effectively and
accurately.
