What it teaches
A buzz shows whether your air comes out evenly. Uneven air, uneven buzz.
Pick a buzz. "vv", "zz", "mm", or a lip or tongue trill
If a lip trill stops. Keep the air flowing and the lips loose; fingertips at your cheeks help
Even all the way. Like a steady breeze, not a gust
What you sing
- Easy and medium-soft; stop if you feel dizzy, wheezy or tight. Hold your buzz over the drone to your goal: "vv", "zz", "mm" or a trill, your pick. A trill may run shorter: stop while it's even.
Singing safely
Don't lock your stomach. Stop if you feel dizzy, wheezy or tight, and sit for long holds. With asthma, another lung or heart condition, or if pregnant, keep holds short and easy. Skip it when hoarse or ill.
