How to use it
Make the command earn its place.
Use the style or production brief to describe this sound. Specify the instrument, voice or texture it should affect; a bracketed label is not a guaranteed control. Keep a small set of compatible directions and separate them from the words to be sung.
Intended effect
Ask for attack and forward movement through performance and rhythm.
Limitations
Aggressive is ambiguous: it can affect vocal delivery, distortion or the whole mix. Name the element you mean.
A useful comparison
Compare forceful drums with an urgent vocal; decide which creates the intended tension.
If removing the tag would not change the intended energy, voice, texture or arrangement, it is probably not adding useful direction.
Examples describe a musical intention. They are not guarantees that a generator will follow every cue. Keep your lyrics and settings fixed, change one direction at a time, and save the prompt, model/version and result you compare.
Editorial review: 5 September 2026. No model-specific generation test is claimed for these examples.
