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.
-
Temperature: cold = flat,
hot = sharp
-
Reed strength: hard
reed = sharp, soft reed = flat
-
Embouchure: (usually
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
too generalize.
-
Dynamic range: Hard 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 and embouchure.
