# Breath
## What is Breath
Just like human singers, adding a breath at the beginning of a sentence usually makes the vocal performance sound more natural. This is especially helpful for long sentences or high notes, where breaths provide a sense of realism and emotional connection.
Breath is the first tab in the AI parameters panel, allowing users to add breaths to the beginning of vocal lines for enhanced realism and expressiveness.
## Editing Breath
