Cinematic electronic pop with emotional female vocals, soft piano intro, atmospheric synth pads, deep bass, crisp modern drums, and subtle orchestral strings. The song begins intimate and restrained, gradually building into a powerful uplifting chorus with wide harmonies and a memorable melodic hook. Bittersweet but hopeful mood, polished production, dramatic dynamics, modern soundtrack feel, suitable for a night-drive movie scene.
Google Lyria 3.5 is Google's flagship music generation model for full-length songs. Describe the track you want in natural language — genre, mood, tempo, instruments, vocal style — and get a complete song of up to about three minutes with expressive vocals, timed lyrics, and a full arrangement with verses, choruses, and bridges. Write your own lyrics with section tags, or ask for an instrumental. Optionally guide the mood with a reference image.
Full-length songs Complete tracks of up to about three minutes with coherent structure — intro, verses, choruses, bridges, and outro.
Expressive vocals and timed lyrics Richer musical arrangements and more natural vocals than Lyria 3 Pro, with lyrics that follow your text closely.
Bring your own lyrics
Add [Verse], [Chorus], and [Bridge] tags in the prompt to control the song structure, or add timestamps such as [0:00 - 0:10] Intro to shape the timeline.
Multilingual Write the prompt in the language you want the song sung in; the vocal style adapts to the language.
Image-guided generation Upload a reference image to inspire the musical mood and atmosphere.
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | 1-5,000 characters. Description of the song: genre, mood, tempo, instruments, vocal style. Include your own lyrics with section tags, or write "instrumental" for no vocals. |
| image | No | Reference image to guide the mood and atmosphere of the generated song. |
[Verse] / [Chorus] / [Bridge] tags, or add timestamps to control when sections start.$0.10 per generated song. Billed per generation, not per second or token.

time.sleep(2)Lyria 3.5 Music is a Google model for audio generation, exposed as a REST API on WaveSpeedAI. Google Lyria 3.5 generates full-length songs up to about three minutes with expressive vocals, timed lyrics, and complete arrangements from text prompts and optional image input. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.
POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID. Poll the result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates Python, JavaScript, and cURL examples for submitting requests and polling results. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/google/google-lyria-3.5-music.
Lyria 3.5 Music starts at $0.1 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.
Key inputs: `prompt`, `image`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/google/google-lyria-3.5-music.
Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.
Commercial usage rights depend on the model's license, set by its provider (Google). Check the provider's applicable terms and WaveSpeedAI's Terms of Service before commercial use.
