The Rim Blown Embrochure

In order to make a sound on a rim blown flute you have to do three things simultaneously:

  1. Occlude the end of the flute

  2. Create a thin stream of air which blows directly across the cutting edge

  3. Create an opening in front of the cutting edge to make a sound hole

The original flute from the broken-flute cave in Arizona, had only a continuous thin rim for the embouchure.  

This style of embouchure was probably played either obliquely

 

 

 

 

 

 

 

 

or intradentally

If you would like to hear how these sound listen to Marlon Magdalena at https://youtu.be/Fb8-ksHbI1A?feature=shared

My more recent adaptation of the embouchure has in internal ramp, based on the southern Chinese Xiao. The Xiao is a meditative instrument designed to create pure tones. This is closer to the sound I find so haunting in the ancestral puebloan flutes,

This is a diagram of the more recent embrochure adaptations.
