Energy levels: loud is not the same as intense
Energy is density, dynamics and performance intensity — control it separately from tempo and volume.
Three dials people confuse
Beginners treat energy, tempo and loudness as one control. They are three. A doom metal riff at 60 BPM is enormous energy; a busy drum-and-bass break can feel weightless. If you only ever write "high energy", you are really writing "fast and loud", and you lose access to the slow-but-crushing and fast-but-airy territories entirely.
| Dial | What it controls | Prompt words |
|---|---|---|
| Tempo | Events per minute | 80 BPM, uptempo, half-time feel |
| Density | How much is happening at once | sparse, layered, wall of sound, minimal |
| Intensity | Performance commitment | restrained, driving, ferocious, gentle |
Words that move each dial
- Low energy: subdued, sparse, hushed, floating, unhurried, understated, restrained dynamics.
- Mid energy: steady, grooving, mid-tempo drive, warm and rolling, relaxed but moving.
- High energy: driving, propulsive, explosive, relentless, full-throttle, maximal, thunderous.
- Energy shape: builds from sparse to full, drops to half-time in the bridge, one-step lift into the final chorus.
Ask for an energy shape, not a constant
Tracks that hold one energy level for three minutes feel flat no matter how good the sound is. The fix is to describe a trajectory. "Starts hushed with solo piano, drums enter at the second verse, full band and doubled vocals by the last chorus" gives the model a curve to follow. Even a single sentence of shape usually produces a more musical result than any number of intensity adjectives.
Keep the shape coarse. Two or three energy states across the song is enough; asking for a different feel in every section usually just confuses the arrangement.
Example
Practice
Write the same prompt three times at three energy levels, changing only density and intensity words and keeping genre, tempo and instruments identical. Generate one of each. Listening back-to-back is the fastest way to learn which words in your vocabulary actually move the needle and which the model quietly ignores.
