LoFi Jazz Generator

Lofi Jazz Generator creates original smooth jazz, on demand. Every track is freshly composed — not streamed, not looped from a library. Just pure, procedurally generated music that breathes like the real thing. Inspired by the intimate warmth of Norah Jones, the soulful groove of Walter Wolfman Washington, and the modal elegance of David Gilmour, every session produces something genuinely new. WHAT MAKES IT DIFFERENT No two plays are identical. The generator composes original melodies, walking bass lines, jazz chord voicings, and brushed drum patterns in real time — drawn from jazz theory, not audio samples. Nine distinct chord progressions keep things harmonically interesting: - Classic ii–V–I and I–vi–ii–V turnarounds - iii–VI–ii–V and IV–iii–vi–V for soul and gospel flavor - A hypnotic Dorian modal vamp - The dark minor ii°–V–i - A bebop-flavored tritone substitution - And more CONTROLS THAT FEEL NATURAL - BPM slider — dial in anything from a slow late-night 60 to a brisk daytime 100 - Density slider — pull the music back to a few sparse, breathing notes, or push it forward into a fuller, busier texture - Mix sliders for Piano, Guitar, Bass, and Drums — shape the sound to your room and your mood - 8, 16, or 32-bar loops SAVE WHAT YOU LOVE When a seed catches your ear, star it. Your favorites are saved locally and ready to replay anytime — perfect for sharing a mood with family or rediscovering a session days later. SEED SYSTEM Every piece of music has a unique seed — a short code that recreates the exact same composition every time. Enter a word, a name, or any text to generate a specific piece, or go fully random and see where it lands. A Half-Eaten Toast creation. What's New: 1.0 - Initial release
