Surprise!! The key to a great vocal warm up isn't singing!  Singing is what you do AFTER a great warm up!  The SWAL Warm Up gets your voice ready to sing!
 
Comprised of a combination of exercises from the SWAL Breathing, Placement (Diaphragm), and Placement (Sinus) Albums.  Additionally including throat exercises, the sequence of these exercises allow you to warm up gradually and fully before singing.
