Hello, -- I hope your singing is going well these days. Sometimes it's difficult to find time to work on a singing dream, but I encourage you to find just a few minutes 2 or 3 times a week to sing some scales, learn a new song, or just sing for the love of it!
To give you a little help with that, here's a daily warm-up (E-stretch) that is useful for high notes and for ease of singing. Even if you've done it before, try it again!
