All Northern Brass models are mathematically and acoustically designed by GR Technologies to create unique high efficiency mouthpieces that are capable of much more than just assisting the upper register.
Originally designed and manufactured by GR as custom designs made for Bruce Lee to help solve the problems inherent in mouthpieces designed for upper register work, and for efficient all around playing.
Why Northern Brass?
Very high alpha angles can not be played well by most players. The sound becomes brittle and articulations are very sloppy. This is also the major cause of "Bottoming out". We at GR call it "Death by Alpha Angle". Many manufacturers use a very high alpha angle in their "upper register" mouthpieces.
One the contrary, very low alpha angles can make articulations harsh and sound very tinny. Often initial attacks will be accompanied by the dreaded "Air Ball". Some manufacturers incorporate the low alpha angle in their "upper register" designs. If your mouthpiece wall goes almost straight down from the rim, you have a very low alpha angle.
GR designed the NB mouthpieces keeping in mind first, an alpha angle which is playable by the majority of players. This unique alpha angle was developed in order to keep the chops supple and free to vibrate, yet provide support and fast, clean articulations. Players will experience a much broader spectrum of sound with NB compared to many other commercial / lead designs. Higher as well as lower overtones are full and in focus.
Northern Brass Mouthpieces are known for their solid upper register, but not at the expense of producing a good sound in the low and middle registers, pointed articulations, and acrobatic flexibility make the NB some of the most versatile mouthpieces available.
