This exercise will work on any instrument. You should vary the tempo of the metronome as your skills increase. Counting aloud is imperative. No counting in your head or mumbling. Speak boldly and clearly as you play. The first two measures are counted only. You begin playing in measure three.
You've got to learn your instrument. Then, you practice, practice, practice. And then, when you finally get up there on the bandstand, forget all that and just wail.
