Ladies, your belt zone is around B flat, B, high C, and high D. This is the area where we usually start pushing and tensing to make the sound more “powerful”.
One of the best things you can do as a singer is pay attention to consistency and tone of your voice. All the notes (below and above your passagio around A above middle C), should “feel” the same. They should resonate the same. You should not feel any undue strain in your throat.
What I mean by this is simply allow the sound to remain the same. Do not try and make the high notes more powerful or “more” than they need to be. They may appear breathy at first. That’s OK.
They simply need to stay connected.
Once connected, your power will come from focus that happens far below the vocal cords….deep within the body……the energy exhibited when holding back breath and creating a balanced pressure above and below the vocal cords.
