Trombone lesson: Brass embouchure with vowels

Using vowels to improve and optimize your trombone embouchure

I have written a lot about about air flow and keeping the throat wide open while playing trombone (and other brass instruments). Here is a really cool trick to improve your embouchure and make sure that you get the most out of your efforts. When you get it right, you will probably experience that your playing will be a lot more effortless, both in the high range and low range!

Your lips are not to be compared with a guitar string that produces a higher pitch the more you stretch it!!!! This is a very common mistake, and a dead end for trombone and brass embouchure. When you get it right, you will be amazed how little effort is actually needed, regardless of the range you are playing in.

The right vowels for trombone playing
I have found that the vowels A (as in Argentina) and Y (as in ypsilon) work best for a good trombone embouchure.

The vowel A is great for low and mid range, amking sure that the air flowing freely and helping you to achieve an open throat. Also note the tongue position while saying “Aaa”! You’re tongue is laying flat in the bottom of your mouth, right?

The vowel Y is great for mid/high range, making your mouth slightly narrower. Please note that your tongue is now quite high up in the mouth, helping to shape and sharpen the air flow. See the pic below for correct use of vowels for trombone playing.

I have seen (and heard) far too many players using the vowels E (as in enter) and I (as in interaction), with a very bad result, especially when playing in the high range. The sound of the instrument will be flat and without overtones, and there will be a very strict limit for how high a player can play. Getting beyond these limits using the vowels E or I, is like trying to get your lips through a brick wall. Quite hard and painful with other words. Are you one of these players? Take a look in a mirror while working your way up in the high range, starting on a comfortable Bb. If your mouth gets wider as the pitch gets higher, you are in trouble!

    1. Really good advice. I will work on this. One thing that helps me is making a trough with my tongue. Sides up on teeth and the trough gives a place for the air to go.
