A mouthpiece is designed in such a way that it concentrates, or forces sound across a column of air. How did you do this with the straw instruments you designed last week?
your mouth has a big sound and it is forced through a smaller hole in the straw and then is released through the opening,it changes when You cut a shape into the top or press lips to it
we cut it in to the shape of a triangle so it was like a wind instrument
