This exercise is for developing the moveable embouchure, but also the sound
and flexibility. It is based on an exercise from the book
"Thoughts on playing the Horn well" by Frøydis Ree Wekre, and the book "Mastering the Tuba" by Roger Bobo.
- Play slowly on the mouthpiece.
- Focus on a smooth glissando and the opposite, a clear octave jump.
- To get a good glissando, try to hear the full cromatic scale and
slide through all those notes.
- Ascend at least one octave up, in half steps.
Play it very gently. Keep lips together and a normal embouchure in the pedal range.
If the pedals are difficult at first, start on low G.
Can be played on lips only in front of a mirror to see the movements
(rolling in and out) of the lips. Also on instrument - keep a very gentle touch
between lips and mouthpiece to enable a smooth glissando.
