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.
