Bocals come in three common lengths, with
2 being standard, 1 being shorter (sharper) and 3 being longer (flatter). There
are also the rarer sizes of the longer 4 and the shorter 0 and 00. It
harms response to pull the bocal out because of the "bubble" created
in the receiving tube.
= flat, hot = sharp
reed = sharp, soft reed = flat
directly related to reed strength) loose embouchure = flat,
pinched embouchure = sharp
Range: lower notes
are sharp on many bassoons, but the bass joint can be pulled a
little from the boot, because there is not bridge key between those
two joints. High range depends on too many factors
to answer this one! Experienced players flatten in extremely
loud dynamics. Softer dynamics are harder to generalize. Young players
usually do not have a wide dynamic range, and the problem
of flatting in a diminuendo is really caused by reed, air
