Not every track needs a singer. A voice-over needs a bed that stays out of the way, a stream needs a loop, a short needs eight bars of energy, and a writer needs something to write over. eroq's [Music One](/models/eroq-music-one) makes all of those with one switch: **Instrumental**.

## How to make an instrumental

1. Open [Music](/studio/music).
2. Switch on **Instrumental**. The song renders with no vocals and the lyrics are left out.
3. Describe the sound. In Simple mode, one sentence: "a slow lo-fi hip-hop instrumental for a rainy night drive, dusty drums and soft keys". In Custom mode, put the same words in Style.
4. Pick a length (30 seconds to 4 minutes, in steps of 30) and one or two takes, then Generate.

Each take lands in your Library as an MP3, 320 kbps, 48 kHz stereo, with no download cap.

## Writing the style for a beat

A beat prompt is all sound and no story, so be specific about the parts a producer would name:

- **Genre and era:** "late-90s boom bap", "2010s trap", "80s synthwave", "modern lo-fi".
- **Tempo:** a BPM ("86 BPM") or a feel ("half-time", "driving").
- **Drums:** "dusty breakbeat", "808s and rolling hi-hats", "brushed snare", "four-on-the-floor kick".
- **Harmony and lead:** "Rhodes chords", "detuned saw pads", "nylon guitar", "solo cello".
- **Texture and mood:** "vinyl crackle", "tape warmth", "wide reverb", "tense", "hopeful".

Describe the sound rather than naming a producer or an artist: genre, era and instrument words are what Music One follows.

## Starting points

Paste any of these into Simple mode with Instrumental on:

- **Study loop:** "A calm lo-fi hip-hop instrumental, 80 BPM, Rhodes chords, dusty drums, vinyl crackle, rain in the background."
- **Trap beat:** "A dark trap instrumental, 140 BPM half-time, heavy 808s, rolling hi-hats, eerie bell melody."
- **Stream intro:** "An energetic synthwave instrumental, driving bass, bright arpeggios, gated drums, night-city mood."
- **Documentary bed:** "A slow cinematic ambient instrumental, warm strings, soft piano, low drones, hopeful and patient."
- **Product video:** "An upbeat acoustic pop instrumental, handclaps, ukulele, light percussion, sunny and clean."
- **Thriller tension:** "A tense orchestral underscore, pulsing low strings, ticking percussion, rising dread."

## What it costs

Music One bills 3 credits per started 30 seconds, per take, vocals or not:

- a 30-second loop: 3 credits;
- a one-minute bed: 6 credits;
- a four-minute backing track: 24 credits.

Two takes, the studio default, cost twice that; a take that fails is refunded on its own. No plan is needed: a $10 pack of 1,000 credits pays for instrumental at 6 credits a minute, one take.

## Putting the beat under something

- **Under a voice-over:** render the narration in the [voice studio](/studio/voice), then lay both on the [Editor](/studio/editor)'s timeline and turn the bed down under the voice. Pick the instrumental length to cover the narration.
- **Under a film:** open the song under Your songs and press **Score a film**: [Cinema](/studio/cinema) starts a film on the track, you build the scenes on top and export an MP4.
- **Under a short:** a 30-second take covers most shorts. Keep the same Style words from video to video and your channel gets a sound.

## Limits worth knowing

- **No stems.** You get one stereo MP3, not separate drums, bass and keys.
- **No loop points.** A take is a piece of music with a start and an end, not a seamless loop; trim it on the Editor's timeline.
- **Length is a target.** A track can find its ending a little before the length you chose; the Library shows its real length.
