For music experiments, the strongest starting points are Suno for changing a song’s style, Google Lyria for controlling track duration and exploring image-inspired music, and Interactive Music Theory Lab for testing melodic and harmonic ideas. Beat Shaper and Fadr suit hands-on beat and remix experiments; two prompt labs help you shape prompts before generating. The ranked list below sticks to tools with documented features that support those experiments.

1. Suno: Best For Rapid Song Variations
Suno is the most flexible pick here for exploring how one musical idea changes across complete generated songs. Its style controls include weirdness and style sliders, along with Voices, Inspo, exclusions, and vocal gender. Try keeping the core idea fixed while changing one control at a time—for example, compare a restrained style setting with a more unusual one, then use exclusions to steer away from an element you do not want.
The free tier is described as allowing up to 10 songs a day. Suno says Pro includes commercial use rights; check the current plan terms before using outputs commercially. If you experiment with vocals or source recordings, use material you have permission to use and review Suno’s terms.

Google Lyria offers useful controls for exploring a musical idea at different lengths, from a short clip to a full song. It can also turn an uploaded image into a track, and its documented controls include vocal style and acoustic preferences. A practical experiment is to start with a clear image, ask for a track that reflects it, then vary the requested duration or sound preferences. Lyria can be tried in Google Flow Music and Gemini; check those services for access, device compatibility, and applicable terms.

3. Interactive Music Theory Lab: Best For Testing Melodies And Harmony
Interactive Music Theory Lab is a browser-based way to work through composition ideas: build a melody over a chord progression, generate a standalone melodic idea, or explore chord and harmonization recommendations. Its 100-plus scales include major, minor, modes, jazz, and world music. For a focused exercise, hold a chord progression steady while exploring a melody in different scales, then export an idea to MIDI or PDF. It is free to use without an account. Audio upload can detect chords from MP3 or WAV files; check the site for supported devices and its terms before uploading material.
4. Beat Shaper: Best For Editing Electronic Beats
Beat Shaper is aimed at electronic music production and lets you generate and edit drums, basslines, synth parts, loops, and arrangements in a browser workspace.

Documented styles include Techno, House, Acid, Drum & Bass, Hip-Hop, and Trance. Starter downloads are limited to MP3 and personal, non-commercial use; Creator and Producer include commercial use. Check the plan details for export options and rights before choosing a workflow.

6. Suno Prompt Generator Lab: Best For Building A Prompt Before Generating
Suno Prompt Generator Lab creates prompt text rather than music. Its builder lets you specify style, vocals, BPM, instruments, structure, lyric direction, and avoid rules, then copy and revise the result. That makes it useful when you want a repeatable experiment: keep the style and structure choices steady, change one variable such as instrumentation, and compare the prompt versions before spending generation credits. The site also provides short, detailed, Suno-style, Udio-style, lyrics, and negative-prompt formats. Check the site for mobile usability and its terms.

7. Suno Prompt Lab: Best For Combining A Few Style Choices
Suno Prompt Lab is another prompt-building option. Its documented controls let you blend up to two genres and select up to three sonic anchors; its Full Builder exposes every parameter. Use it to explore combinations systematically: hold the mood steady, change one genre or anchor, and compare the resulting prompt text. The tool describes its styles as built from professional TV and sync experience; it does not generate audio. Check the site for access details and terms before using its prompts.
