What is a commercial trumpet backbore?

Commercial music is the inclusion of virtually any style of music from pop, rock, funk, blues, and others. The typical commercial backbore tends to lean on the efficient side, but that truly is a personal preference of the player. It comes down to one word, balance! The player needs to have the balance of resistance from the horn, mouthpiece, and their body. For many commercial players they are looking for a backbore that offers more resistance to assist with their efficiency of themselves and their horn. What if a player is using a very tight feeling trumpet that provides an extreme amount of resistance? In this case would a very efficient backbore be needed? Maybe not. Whether you’re using our more free blowing #0 backbore, or our most efficient offering the #C4, the balance of resistance is the key.

Pickett commercial backbores present more initial resistance to the player given their slower taper expansion after the throat and longer throat sections.  This shape combination provides a solid efficiency and resistance to push against.

Our original commercial backbore, the C4, was developed with Vince DiMartino and Doc Severinsen.  There were test backbores named, A, B, C, and D, with different parameters, 1, 2, 3, 4, and 5 - the combination C4 presented itself as the best through our empirical testing. Next came the V backbore, slight variation of the C4, offering a slightly larger volume. The R is the most recent commercial backbore that has the unique feel of a larger backbore, but with the compression and efficiency of tighter commercial backbores.  The result is a big sound, but that doesn't swallow the player up.
