Your words. Sung.
Give us your words and the sound in your head — a ballad, a dance anthem, a lullaby for someone small — and our own Impromptune engine turns them into a finished song. Free to generate and listen. Yours to keep.
Sparse piano and swelling strings — a rain-against-the-window heartbreak ballad, composed and sung by Impromptune from a written brief.
Three steps between a page of words and a song you can play for someone.
Paste your lyrics into the Song Brief Builder and describe the sound: genre, mood, tempo, voice. Your words stay yours — the engine sings what you wrote, it does not improvise new lyrics.
Impromptune v1.0 — our own program, built on a licence-free open model — composes and performs your song: melody, instruments, beat and vocal, in one render.
Generating and listening are free. When a song is the one, a subscription unlocks downloads — clean audio files, licence-free, ready to share anywhere.
