K-pop style instrumental for a product video: a brief with no artist

A K-pop style instrumental for a product video is a brief about structure and sound, not about a group. Google's music generation page, read on 2026-10-05, says safety filters block artist voices and copyrighted lyrics, so describe a style by its instruments, tempo and mood rather than by an artist's name. On Sume the default sume/music-auto resolves to Lyria 3.5 today, and the Music Router docs say that mapping may move without notice, so pin lyria-3.5 if you need the same engine tomorrow.

Brief it by parts

• Tempo and feel: 120 to 128 BPM, bright and bouncy, with a half-time breakdown.
• Sound: glossy synth stabs, punchy bass, snappy claps, a chopped vocal-style synth hook with no words.
• Structure: four-bar intro, build, drop on bar nine, short outro. Google documents timestamp and section tags for Lyria 3.5 on its music page.
• No vocals: ask for an instrumental explicitly; Google lists an instrumental option.

Cost and assembly

One generation is a fixed $0.125 on Sume. Google lists Lyria 3.5 at $0.08 per song on its pricing page, read on 2026-10-05. Generate two or three takes, since the model is single-turn and cannot be edited after the fact, then place the best under a 15 to 30 second product cut with a Timeline soundtrack block: set fade_out_seconds up to 10 so the drop does not end abruptly, and keep gain_db between -60 and 12.

Time the product reveal to the drop. Order and trim your video slots so the hero shot lands on the bar where the bass drops, then re-run the unbilled plan call to check the output length before paying $0.10 for the render. If the first cut feels flat, change one axis in the brief, such as tempo or the lead instrument, and generate again rather than stacking effects on a track that is wrong at the source. Keep the winning prompt next to the project so the next product video can reuse the sound.
