چکیده

Emotion adds affect and improves understanding in humancomputer interaction. Emotion can not only be conveyed to the human user using visual cues like color or facial expression, but also using music. This paper describes development of CAM (Cellular Automata Music) that generates music using cellular automata and adds affect by modifying it according to a few simple rules that are based on detection of emotion in music. Input for the system is emotion which is given as a point on the two dimensional emotion space (2DES). The music is very basic because it lacks properties like patterns or chords, but it should be good enough to be used as background music. The system is evaluated with a user experiment in which participants were asked to indicate perceived emotions while listening to a few fragments. This article describes the state of art of music generation, detection of emotion in music and generating affective music and discusses the design and results of the experiment.

Computer-generating Emotional Music: the Design of an Affective Music Algorithm

This paper explores one way to use music in the context of affective design. We've made a real-time music generator that is designed around the concepts of valence and arousal, which are two components of certain models of emotion. When set to a desired valence and arousal, the algorithm plays music corresponding to the intersection of these two parameters. We designed our algorithm using psych...

A Functional MRI Study of Happy and Sad Emotions in Music with and without Lyrics

Musical emotions, such as happiness and sadness, have been investigated using instrumental music devoid of linguistic content. However, pop and rock, the most common musical genres, utilize lyrics for conveying emotions. Using participants' self-selected musical excerpts, we studied their behavior and brain responses to elucidate how lyrics interact with musical emotion processing, as reflected...

The minor third communicates sadness in speech, mirroring its use in music.

There is a long history of attempts to explain why music is perceived as expressing emotion. The relationship between pitches serves as an important cue for conveying emotion in music. The musical interval referred to as the minor third is generally thought to convey sadness. We reveal that the minor third also occurs in the pitch contour of speech conveying sadness. Bisyllabic speech samples c...

Ranking-Based Emotion Recognition for Experimental Music

Emotion recognition is an open problem in Affective Computing the field. Music emotion recognition (MER) has challenges including variability of musical content across genres, the cultural background of listeners, reliability of ground truth data, and the modeling human hearing in computational domains. In this study, we focus on experimental music emotion recognition. First, we present a music...

Influencing the Perceived Emotions of Music with Intent

Music is an immensely powerful affective medium that pervades our everyday life. With ever advancing technology, the reproduction and application of music for emotive and information transfer purposes has never been more prevalent. In this paper we introduce a rule-based engine for influencing the perceived emotions of music. Based on empirical music psychology, we attempt to formalise the rela...
