Stagnant Water and Long Notes

Ever been hiking? If you needed to drink from a stream, would you choose the moving water or the water that is just sitting there?

(OK, I’m hoping the answer here is pretty obvious).

Long notes are like that. Don’t let them become stagnant. They should always feel as if they are moving somewhere (either building or decaying).

Blow through the end of the note.
Blow into the next note!
