Most basically, the bassoon will produce a higher volume sound when a higher volume of air is moved through the instrument. In order for this to sound pleasing, however, the aural cavity, embouchure, and reed tip aperture must relax and expand to accommodate a wider airstream. Consider the graph below as you explore different dynamics on the bassoon.
