The Difference in Rim Size

Compare your lips against a mouthpiece to a violin string. Like a shorter string, a shorter lip area (created by a smaller inside diameter mouthpiece) will produce a shorter vibrating surface. This shorter surface, as well as the added tension of the length, are what helps produce pitches in the upper register.

The longer string and the larger inside diameter of the mouthpiece add length to the vibrating surface that helps create a lower pitch with a thicker texture of sound.

Take This Test

Many players will choose a mouthpiece size because the rim feels good. While feel is important, it should not be the main criteria for selection.

First you need to have a realistic understanding of your musical range. Your musical range is not based on how high you can play, but how high you can play without the sound becoming thin and forced.

With this knowledge, play a simple melody or a series of scales that takes you into all registers. Listen to the sound when you play. If the sound becomes thin and unfocused in the upper register, then chances are good that when you move into the extreme lower register, the sound will be too spread and "tubby".

Conversely, if the lower register is unfocused and thin sounding, then chances are that the upper register will be too strident and harsh when you play loudly.

Choose a rim size that will help you produce an even sound in all registers.

How Cup Depth Affects Sound

Many times players believe that their playing ranges are based on the depth of a mouthpiece cup--if the cup is shallow then they will be able to play higher. The truth is, range is based on your ability to vibrate your lips at a given frequency. The cup depth will not affect how fast you can vibrate your lips. What the cup depth will affect is the color of the tone you are capable of producing. The deeper cups will assist in producing a thicker, darker sound. The shallower cups will support a register that you already are capable of producing, as well as help create a more brilliant sound.

What Do the Sizes Mean?

Laskey trumpet rims are listed by the approximate inside diameter measurement. If a mouthpiece measures .680 inches on the ID, the size is the last two digits or 80.

Throat Size

Standard throat size on all trumpet mouthpieces is .144 (#27). Our standard backbore has been designed to provide ideal intonation, support and projection. Additional backbore and throat sizes are available on special request.
