shatter glass with my voice

I have to find glass thin and pure enough to ‘ting’ on just the right frequency with my voice. I can reach a top C, but not at full power. My full power range, the total, over-the-top throat-rattling, chest-shaking, teeth-wobbling (not that my mouth moves, because that’s just baaaaad technique) highest note using the awesome power of my operatic voice is top B flat, just a semitone below my highest ever note, top C. And I can be quite loud. The other night at rehearsal, there were at least 50 other (true)sopranos with me when we did this warm up in opera-style, and a tenor on the other side of the room zeroed in on me and complimented me on the lovliness of my voice (so did the young woman who was next to me a few chairs away, and the woman in front of me who bore the brunt of my opera voice). I get a bit moody when the other natural sopranos can reach higher than me, because I’m a mezzo-soprano, but I actually have a bigger voice than them, with the fullness in my middle range they lack. So there!
