Have you figured out your vocal habits yet? Are you mixing?
Are you getting through your passagio without a flip?
Are you feeling strain in your throat as you sing your high notes?
There are many facets to singing well, but mastering your middle voice (mixing) is key to building strength and stamina.
Try the nasty buzzy hum exercise. Go from your lowest notes to your highest notes. What do you feel? Are your high notes dull?
If you are mixing well, you will siren through your entire vocal range.
If you feel strain or an awkward feeling in your throat, then try again….but lighter. Find that “light is right” coordination that gets you through the middle voice. You may find that your low hum is weak. That’s OK, this is where you need to be. It will get stronger as you focus in on the sensation of allowing your voice to resonate in your “head” as well as your “chest”. Add a puppy dog whimper sensation to your hum. This will help get those cords to close.
