One of the most important aspects of playing a wind instrument is air. The proper amount of air must be used efficiently at all times. Metaphorically, this concept can be learned by turning on a faucet and listening to the fast and steady flow of the water. This inconsistency in the water flow is the way in which amateur musicians blow into their instruments. Unevenness is not the result of sloppy fingers or lack of talent.
Metronomic discipline produces evenness.
Every Note Is Important . The clarity and detail of every note is important whether it is a fast or slow note. The notes should never be so fast that every note is not clearly heard. The ear should be prepared for the change to every note by the note preceding it. The mastery of this concept is conditional upon mastery of the previous three skills.
