Never, never try to sing with laryngitis, it will hurt your vocal cords.


You need to recover completely, before you even try. Please do not take a chance on something that can give you pleasure the rest of your life.
Reply:Make a siren sound, loud to warm up the vocal chords. Sing the Star Spangeled Banner. It is a great song with good rang in notes to help warm you up.
