EmoteControl

Abstract

Numerous computer systems have been designed for music emotion research, aiming to identify how different structural and expressive cues of a musical piece affect the emotion conveyed by the music and perceived by the listener. However, most systems are either offline systems, which work by pre-rendering different variations of the music, or real-time systems, which focus mostly on expressive cues. This paper presents a new system called EmoteControl, which allows changes to be made to both structural and expressive cues (tempo, pitch, dynamics, articulation, brightness, and mode) of a musical piece while it plays in realtime. First, a brief overview of previous computer systems will be given, followed by a detailed explanation of EmoteControl's interface design and structure. A smaller-scale version of the system will also be described, and specifications for the music inputted in the system will be outlined. Interface limitations will be noted, and user evaluation cases for both versions of the interface will be discussed. A demonstration of the interface will be presented, featuring specifically composed musical pieces.
