Gesture-enabled interfaces, systems, methods, and applications for generating digital chord and lyric compositions

Abstract

A music composition application for mobile devices provides gesture-driven interfaces for rapidly creating digital music compositions with chord and lyric notations. In certain embodiments, a gesture-driven composer environment can be configured in various modes to enable end-users to input and align chord notations with lyric notations, align chord notations with beat notations, and incorporate the chord with musical scores. The chord notations can be stored as chord objects with embedded information that can be propagated across the different modes, and the application facilitates transitions among modes while maintaining consistent chord information. Gesture-based inputs allow users to easily insert, reposition, and customize chord notations. The application also provides audio playback functionality by translating the digital music composition into analog audio signals.
