Bach Trumpet Mouthpiece Classic Series

Vincent Bach was a rare combination of artist and engineer. He constantly changed his mouthpieces in search of the perfect design. It wasn't until the mid 1960's that he stopped and finally settled on more standardized design.

It was around this time that the formalization of the 27 throat and backbore to cup letter (A=24, B=7, C= 10, etc.) created a standard for mouthpiece making that is still used today. These standards are now known as the Classic Series.

Bach trumpet mouthpieces are an industry standard and respected worldwide. Bach Classic Series come in range of standard sizes. We can offer all Bach trumpet mouthpieces in Silver Plate, Gold Plate or Gold Rim. 

Bach trumpet, (cornet and fluegelhorn) mouthpieces have been numbered in an orderly progression from the largest to the smallest diameters and from the deepest to the most shallow cup, each with a choice of rim designs.

Model numbers progress numerically from model #1 with the largest cup diameter, to model #20C with the smallest cup diameter. Cup depths are notated with letters. “A” cups are the deepest; standard cups have no letter designation; progressively shallower cups are marked B through F.

• “A” Models have very deep cups, #24 backbores, and emit a large, dark sound.
• Models with no letter designation have deep cups, #10 backbores, and produce a rich, full, clear tone.
• “B” Models have medium deep cups, #7 backbores, and have a full, Teutonic tone with great volume.
• “C” Models have medium cups, #10 backbores, and are preferred by many players that alternate between B b, C and D trumpet.
• “D” Models have medium-shallow cups, #76 backbores, and produce a sparkling, brilliant tone, especially in the high register. Artists who continually play in the extreme high register use them to advantage.
• “E” Models have shallow cups, #117 backbores, and are designed for use on soprano and piccolo trumpets. Also preferred by extreme high register players.
• “F” Models have extra-shallow cups, #76 backbores, and are also preferred by extreme high register players.
• “V” Models have V style cups. “V” designates a very deep cup, #20 throat, and #25 backbore; “MV” designates a medium deep cup, #25 throat, and #25 backbore; “SV” designates a shallow cup, #25 throat, and #25 backbore.
• “W” Models have a wide, cushion rim for soft, thick lips.
