Entertainment
Overview
VeyrPiano gives users an interactive piano roll inside ChatGPT for creating and continuing shared musical compositions. Users can draw, move, resize, audition, remove, undo, and redo notes; adjust sustain and tempo; and hand the piece to ChatGPT for one bounded additive musical move. Human-created notes appear green and ChatGPT-created notes appear blue, preserving visible authorship as the piece develops. An active composition can be explicitly reopened later and continued from its latest authoritative state.
