Teoot Orchestra is a free music composition studio that runs in a web browser using the Web Audio API. No installation or account is required for playback, layering, and file export. Users build pieces from instrument and sound layers, play them in real time, and shape parts by tuning pitch and waveforms or adjusting filters, vibrato, envelopes, and other expression controls. Built-in models include percussion, bass, guitar, piano, strings, winds, organ, synth pad, sitar, tanpura, tabla, marimba, and simple tones. Scores can be imported or exported through CSV or Excel, including pasted CSV and uploaded spreadsheets. An AI Composer turns plain-English descriptions of mood, instruments, and tempo into composition CSV, and prompts are provided for ChatGPT, Claude, or Gemini workflows. Mixes export as WAV, MP3, or FLAC, with downloads limited to 10 minutes. CSV imports require the complete 70-column header in the specified order.
Who it is for
Teoot Orchestra suits generative music experiments, game-audio prototypes, sound-design teaching, and repeatable scores managed like code. It also fits browser users who want spreadsheet-based composition without an account.
