When blowing, angle slightly downwards over the forearm.
The flute sits just a smidge under the bottom lip. The lip needs to be able to move forward as you ascend through the registers.
The aperture in the lips should be a lovely elliptical shape.
Allow the bottom lip to spread out on the lip plate.
This is the first in a series of posts regarding a basic flute embouchure. Each day as you do your tone exercises you could consider if this tip is of benefit to you and build up a picture of a good basic embouchure.
Cover only about 1/3 of the embouchure hole on the flute. Most of the sound comes out of the embouchure hole so let it out and avoid over covering.
