Availability note
Lyria 3.5 is rolling out through Flow Music. If it does not appear in your account, that does not prove the announcement is wrong; access can vary by rollout, region, account, age, and plan.
What Lyria 3.5 changes
More natural musical development
Musicality is more than clean audio. It includes whether phrases lead naturally into one another, sections feel related, tension resolves, and instruments leave space for the vocal. Lyria 3.5 is positioned as an improvement in those relationships, especially for more complex arrangements.
Better lyric and prompt adherence
A song generator can produce an impressive track that misses the requested story, structure, or tone. The update emphasizes following the user's prompt and keeping lyrics closer to the intended subject. Treat this as an improvement to test, not a guarantee.
More expressive vocals
Google highlights expression and pronunciation. That matters for hooks, dense verses, multilingual lyrics, and emotional changes between sections. Always review consonants, names, stressed syllables, and high notes in the actual exported mix.
Stronger structural awareness
Structure tells the model how the song should travel: intro, verse, pre-chorus, chorus, bridge, and outro. Lyria 3 Pro already supported structured prompting; Lyria 3.5 aims to improve how faithfully the generated track follows that plan.
Direct creative controls
Launch reporting describes easier control over tempo and duration, plus ways to adjust vocals, drums, and bass. Flow Music's earlier official updates also describe section-level changes, lyric rewrites or translations, style changes, samples, covers, and music-video creation with Gemini Omni.
Lyria 3.5 versus Lyria 3 and Lyria 3 Pro
The names can be confusing. Lyria 3 launched for short text- or image-inspired music. Lyria 3 Pro expanded toward full songs and explicit section structure. Lyria 3.5 is the newest update announced for Flow Music, emphasizing quality and control improvements across the song-generation experience.
| Version | Primary position | Best question to test |
|---|---|---|
| Lyria 3 | Fast music creation from text or images | Does the short idea match the intended mood? |
| Lyria 3 Pro | Longer, structured song generation | Does it follow the verse and chorus blueprint? |
| Lyria 3.5 | Updated Flow Music quality and controls | Do vocals, structure, and targeted edits hold together? |
Google's Lyria 3 model card describes text input and music plus lyric output, and notes that the card also covers subsequent versions. Product availability can change faster than the model card.
A better Lyria 3.5 prompt formula
Prompt 1: cinematic product soundtrack
Prompt 2: structured indie-pop song
Prompt 3: revise one weak section
How to evaluate the output
- Prompt match: Did it follow genre, duration, language, mood, and exclusions?
- Structure: Can you identify the requested sections without reading the prompt?
- Vocal quality: Check pronunciation, timing, breath placement, range, and identity.
- Musical continuity: Listen for awkward key movement, abrupt instrumentation, or unresolved transitions.
- Edit stability: When one section changes, did the approved sections remain intact?
- Delivery fit: Test the track under the actual video, voiceover, ad, or game scene.

Rights and release checks
Generated output does not erase input obligations. Verify your rights to every uploaded lyric, melody, recording, voice, and reference. Google's official Flow Music partnership post says Google does not claim ownership of original content generated with Flow Music, while Lyria outputs use SynthID. That is not a substitute for reviewing the current product terms and your distributor's policies.
