20th century Euphonium – Music Instrument

Espana Post issued the stamp series devoted to musical instruments is completed with a new stamp depicting a 20th century euphonium belonging to the collection of the Museo Interactivo de la Música de Málaga on October 5, 2010.
The euphonium is one of the less popular instruments in the West.It is believed to have been invented by Carl Moritz in 1838, although it is also credited to Ferdinand Sommer and Adolphe Sax in 1843.It is built in B flat for concert which means that, by not pressing any piston valve the instrument will produce partial harmonic series in B flat.


The euphonium is a wind brass instrument belonging to the family of the aerophones. It is a conical-bore metal tube which gradually widens from the mouthpiece to the bell.
It is equipped with three piston valves which lengthen the tube to enable it to communicate with other additional tubes, lowering the pitch.
Other elements or parts that make up the euphonium are the bell, the general pump, the valve pumps, a small musical stand, water key corks, valve covers, valve stem felts, a staple and a mouthpiece.
Euphoniums are made of brass, which is an alloy of copper and zinc and depending on the proportions of the mixture of metals, the sound will differ: the more zinc the brighter the sound and on the contrary, the more copper the mellower.  It is a band instrument, often a solo instrument, and also used by jazz groups.

The sound of the euphonium is produced by vibration of the lips on the mouthpiece. The vibration of the lips is achieved by a column of air. Thus this instrument is classified in the family of aerophones.
