Started clarinet 5 months ago. Several weeks ago my instructor tried to get me to blow "fast air" at a steady pace while tonguing for the notes. It was like rubbing my belly, patting my head and chewing gum at the same time. Besides I thought my notes sounded just fine anyway, so I did not really understand his point. I think he concluded that I just needed more time. Then I saw a posting here about a free software program called "Audacity" that allows you to record yourself. So I did. Egads my notes were horrible. Especially at the beginning of a piece the note is like a bell shaped curve and sounds it. It needs to sound steady from the go. Something else to now work on along with the several thousand other things. But, I love the challenge.
