For AI music experimentation, start with Interactive Music Theory Lab for theory-led sketches, Beat Shaper for editable electronic arrangements, and Google Lyria for controlled audio ideation. Add Suno when you need complete vocal songs, Fadr when you want to dissect or remix audio, and the two Suno prompt labs when the experiment is mainly about prompt design.

1. Interactive Music Theory Lab
Interactive Music Theory Lab is the strongest first stop when the experiment is musical structure rather than finished production. Build a melody over a chord progression, generate a standalone melodic idea, or request theory-driven chord, melody and harmonization recommendations. Its scale library covers more than 100 major, minor, modal, jazz and world-music scales.
For reverse engineering, upload an MP3 or WAV file for AI chord detection, then export results to MIDI or PDF. The lab is free to use and requires no account. A practical loop is: choose a less familiar scale, generate a progression, sketch a melody, export MIDI, and continue arranging in your DAW. Check the site’s current export and usage terms before publishing material derived from an upload.
2. Beat Shaper
Beat Shaper is built for electronic-music experiments that need editable parts. Generate drums, basslines, synths, loops and arrangements in a browser workspace, then refine them in a piano roll. Genre, mood, energy and syncopation controls make it useful for controlled A/B prompts such as a low-energy house groove versus a high-energy drum-and-bass pattern.

The generator can produce short, detailed, Suno-style, Udio-style, lyrics and negative-prompt formats. Build three prompts that change one field—such as BPM or vocal direction—while keeping the rest fixed, then run them in the music generator you choose. This site generates prompt text only, so audio rights and output terms come from the downstream service.
7. Suno Prompt Lab
Suno Prompt Lab focuses on curated prompt construction for repeatable ideation. Each style is presented as a complete prompt informed by professional TV and sync experience. Its builder lets you choose up to two genres, up to three instruments and one emotional anchor, with a Full Builder mode for every parameter.
Use it to create a small matrix: keep the emotional anchor fixed, swap one genre pairing, then change one instrument choice. Paste each prompt into your chosen generator and label the resulting audio with the exact prompt version. Because the lab supplies prompt text rather than music, check the receiving generator’s consent, voice, cover and commercial-use rules before release.
