SONATA — Classical & Baroque BGM Generator

SONATA composes real common-practice music — the language of Bach and Beethoven — built on functional harmony, cadences and counterpoint rather than loops. Choose a two-part invention or a fugue with staggered subject-and-answer entries over a walking bass; a flowing arpeggiated prelude; a fiery sonata-allegro with Alberti-bass fortepiano; a graceful 3/4 minuet; a bright rondo whose refrain keeps returning; a set of theme-and-variations that grows more elaborate; a singing adagio; a romantic nocturne with a lyrical, ornamented right hand; a four-part chorale; or a grand tutti-and-solo concerto. An Era slider slides the whole thing from harpsichord-and-organ Baroque through Classical to expressive Romantic, and an ornament control adds trills and graces.

Perfect for elegant menus and title screens, noble courts and manor houses, churches and cathedrals, cutscenes, refined shops and salons, puzzle rooms, and period or steampunk settings.

What you get

• 52 hand-designed scenes across 13 categories — a starting point for every moment in your game.
• 12 musical “forms” you can force onto any scene for instant variation.
• 6 mood sliders plus Form / Meter / Palette / Key / Length menus, a live visualizer, and a ⟳ regenerate button that rerolls a fresh take every click.
• Export OGG and WAV. The OGG is written with LOOPSTART / LOOPLENGTH tags, so it loops seamlessly inside RPG Maker with no clicks or gaps.
• One self-contained HTML file. No installation, no account, no plugins, and no internet needed after download. Nothing is ever uploaded — it all runs in your browser.
• 100% synthesized from scratch with the Web Audio API. No samples, so every track is unique and truly yours.

How to use it

1. Download the .html file (or press ▶ to try it right here in your browser).
2. Open it in any modern browser — Chrome, Edge, or Firefox.
3. Pick a scene, nudge the sliders and menus, and hit ⟳ until it feels right.
4. Export the .ogg for your game (and/or the .wav for a DAW).
5. Drop the .ogg into your project’s audio/bgm/ folder and select it as a BGM. The embedded loop tags make it loop perfectly in RPG Maker MZ & MV (the OGG also works in most other engines — Godot, Unity, GameMaker, Ren’Py, etc.).
