The trombone represents the bass instrument within the family of trumpets and, in Italian, carries the name “big trumpet”. Just like the trumpet, the trombone requires a round mouthpiece and predominantly consists of a cylindrical pipe and flared bell. The most obvious and significant difference is the U-shaped tuning slide, which is plugged onto the trombone tube and can be adjusted to six positions. By this, every natural note of the instrument, which is tuned to B, can be lowered sixfold.
A Breslmair for trombones is characterised by a massive “heavy“ cup, which enables the musicians to produce a rich sound throughout the entire bore.
