bocals
When purchasing
a bocal there are three variables to consider: the bore; the thickness
of the wall and the length.There are also two types of bocal – the modern and the
prewar.The chart below
describes the various bocals which we manufacture.Upon special request, we can also
make a bocal of a different length.
Our prewar bocals all have the same bore which
produces a high-register bocal.They are also very different from most
modern designs in that they have a far greater internal volume (larger
bore) that produces a much brighter sound, is much more free blowing,
and gives a high register that speaks very easily and is very flexible.
The downside to this bocal is that the bottom fifth is sharper and it is
so flexible that some notes (third octave) can tend to sail. The thick
wall variation does improve the compromise.
All of our bocals are available with a normal or thin
wall. The thin wall bocals absorb less energy which results in the
instrument speaking more quickly and playing a little sharper.One
can also choose an unplated or plated bocal. In general, the
unplated are the most vibrant, nickel plating produces a dense
projecting sound while silver plating tends to soften the overall
sound.
