Upon waking, we do have that groggy, "morning" voice. For me, I can speak "normally" if I just do a quick slide. But how long does it take for my voice to be ready to sing?
On days when I wake up no longer sleepy, I have all the notes in my range except the extreme high notes. My breath support and phrasing aren't there. This takes a bit longer to get. Typically, approximately 3 hours after waking up, I can usually be performance ready. Hormones suck though because on some days I can't sing until afternoon and such.
But why is there this delay? Is there any way I can overcome this? If Joan Sutherland doesn't need to warm up to sing high notes, then what's the secret?
I taught a student a few weeks ago who woke up only an hour before her lesson. Nothing was working to her expectations. I did the normal physical exercises while singing to help the breath go: jumping jacks, planks, wall sits, etc.
Once her voice was functioning to her liking, I asked "So how much of warming up was actually the voice, and how much was your support?" There was my answer! And simultaneously the question for all of you! My student said that on a scale of 1-10, it was 7 warming up her voice and 3 warming up her support muscles.
Whenever I need to sing loud or sing a long phrase, my support muscles really need to activate in order for me to sing to my liking. I can typically sing A4 full voice no problem minutes after waking. So for me, my voice doesn't need to wake up, my SUPPORT needs to wake up!!!
These are big muscles compared to the vocal folds! You wouldn't do laborious, physical exercise without stretching and warming up, and so the support needs that same time!
Anyone without dysphonia can wake up and start talking without warming up!!!
YOUR VOICE DOES NOT NEED TO WARM UP! Your support muscles need to warm up!
