After your lesson, audition or performance is over, take time to cool down. While cooling down is often omitted from lists of vocal-health tips, it’s a really simple way to support vocal health for singers. Sigh on a descending note.

Take 5 or 10 minutes to allow your voice to settle back into its normal speaking range.
