Here is some info taken from our GR Mouthpiece Tutorial:
The THROAT, (circled), sometimes referred to as the bore, is the cylindrical section between the cup and the backbore.
The throat can have a very dramatic affect on compression, sound, and resistance. The dimensions of the throat to consider are diameter and length. Many players only talk about the diameter of the throat. The blow resistance is calculated using the length and diameter.
At clinics we often ask the question, "What is more resistant a #22 Bore or a #28 Bore?" It is not possible to answer this question unless you have the lengths as well. Yes, given the same length the #28 Bore would be more resistant. What if the #22 Bore was .250" long and the #28 Bore was .150" long? Believe it or not, the resistance is about the same! You get the picture.
Both length and diameter are needed to calculate blow resistance.
Many trumpeters only consider the bore diameter as this is perhaps the easiest parameter to visualize, and alter.
