The Trumpet on stamp.

The other stamp as part of the musical instrument stamp series of Spain is the Trumpet, a wind instrument belonging to the family of brass-wind instruments as it is made of a metal alloy. This stamp was issued on 9th of April 2010 with face value of 0.34 Euro.

Originally, the first trumpets were made out of bamboo, hollow plant tubes and of sea fish shells. Later on, with the discovery of metals, they began to be made out of bronze or thin sheets of steel up to this day when they are made of an alloy of metals.

The trumpet has a cup shape mouthpiece with brass tubing bent twice into an oblong shape. There are a roughly cylindrical bore which results in a bright, loud sound. The bore is actually a complex series of tapers, smaller at the mouthpiece receiver and larger just before the flare of the bell begins; careful design of these tapers is critical to the intonation of the instrument. Trumpets also have three piston valves, each of which increases the length of tubing when engaged, thereby lowering the pitch. The first valve lowers the instrument's pitch 2 semitones, the second valve 1 semitone, and the third valve 3 semitones. Used singly and in combination these valves make the instrument fully chromatic.
