Vocal Training Lip Trills and Sirens

For several years I've been telling myself that I need to start sharing vocal exercises and after doing one for my takelessons.com profile yesterday, I decided to do a short video today on lip trills and and sirens. The point of these exercises is for you to expand your range, yet it's beneficial to use them at the beginning before you start singing. The warm-ups get your vocal cords prepared to sing. This is the first vocal video, so I'll keep learning how to serve and help the vocalist be more successful. Thanks for your support. What is something that you want to try that would stretch you in a good way? Thanks for your support. Blessings.
