2022Trombone - Set

Its deep and powerful sound makes the trombone an essential part of any symphonic orchestra and other musical ensembles. As with all brass instruments, sound is produced when the player's vibrating lips on the mouthpiece cause the air inside the instrument to vibrate. The pitch is not altered by vents, but by a telescoping slide mechanism attached to the cylindrical tube bent into an elongated "S" shape that varies the length of the instrument to change the pitch. In addition to the basic slide position, there are six other positions, which are all a semitone apart. In the background of the stamp, you can see the main motif of the concerto for trombone in E-flat major by Georg Christoph Wagenseil (1715-1777). The episcopal library of Olomouc in the Czech Republic is home to an autograph of this piece. Georg Christoph Wagenseil was a highly renowned court composer at the court of Maria Theresa and is considered to have prepared the ground for the classical Viennese era. The margin of this small sheet shows an illustration of a trombone with its slide positions and the corresponding tones.
