I have noticed that it is sometimes difficult to get across to a student how to project their sound well when playing a solo for a studio class, jury, recital, etc. (I have previously posted on sound projection on this blog, fyi.) This seems especially true when working with students who have spent most of their clarinet or saxophone careers as section players in a band. As section players, these students work to blend in with a group and not stick out – and “sticking out” is exactly what you want to do on a solo!
Recently, while working with a student on this in preparation for a studio class performance and jury, it suddenly occurred to me to say, “Play like you are first chair.” The student (who was a section player in band) immediately played the solo with excellent sound projection! I have used this comment several times since and it has been very useful in helping students (esp. section players) project their sound.
