Piston Aerosol of the metal family with tuning in contralto or soprano, developed in the late 20s of the 19th century.
The three pistons are in most models positioned after the main tube about halfway along the length of the sound tubing. There is a more pronounced cone between the receiver of the nozzle and the pistons than in the modern trumpet. The shape of the modern bugle mouthpiece is not substantially different from that of the modern trumpet, but the hole is smaller and less conical. The bugle tuned in Sib in unison with the Sib trumpet is the most common, the soprano bugle in Mib is also used regularly. The bugle is usually an instrument transpositor, being written pieces for cornetim in Sib two “semi-tones above its tone”.
The written measure goes from Fa # to C, although some players go up one octave. The types of mufflers used in the trumpet can also be used with the bugle. Body with three cylinders, three pistons and removable nozzle. Poor state of repair, the tuning pump is missing.
