Crowning the Sound....
When students are asked to play forte or fortissimo on the piccolo in ensembles, tone often gets a bit raucous and raw. I think that forte should be replaced by the word FULL...play full and round, so that the tutti orchestral sound has a crown or shimmer added to it by the voice of the piccolo. Instead of driving the tone thru the texture, relax into it, setting the air around you into vibration, which aids projection and reduces the tension in the tone which can make the instrument sound harsh or shrill. Never drive the sound...allow it to live in the space of the hall.
