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
Give the voice a lower centre of gravity and support an intimate narrative.
Limitations
The term cannot guarantee exact pitches or a classical range. Tone, tessitura and melody still need listening checks.
A useful comparison
Compare conversational and sustained phrasing using the same lower-register direction.
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.
