Trombone for Rotary Valves

Trombone for Rotary Valves

A lip vibration aerophone of the cylindrical body metal family. The most common trombones are understood to correspond to the tenor and bass of the trumpet [soprano-alto]. In its most usual form, the trombone is characterized by a telescopic rod with which the player varies the length of the tube; hence the term “trombone of rods”.
Although Heinrich Stölzel, a co-inventor of the piston, considered the application of his invention to the trombone, it was other Vienna-based builders who in the 1920s employed the double piston system to this instrument. Made of high, tenor and bass tessitures, piston trombones peaked in popularity shortly after the mid-19th century. In 1890, according to Constant Pierra, Germanic and Italian orchestras often used a bass trombone of pistons, and until the mid-twentieth century piston trombones (often side by side with trombones of sticks) were common in bands and orchestras of theaters in Latin countries, Eastern Europe and Asia (…) Since about 1840, instruments for banded and marching bands have been produced in various vertical (tuba) and circular (helicon) models. These included the “Armeeposaune” (ger: “army trombone”) invented by V. F. Cerveny de Hradek Krávolé in 1867; the instrument used a system with rotary valves, and was manufactured in various tunings, from the top in F to the double bass in Sib. The tenor and bass instruments are often equipped with a fourth valve which, like other similar wind instruments, lowers the pitch to a perfect 4th, but the pitch of this instrument is impaired. The constant need to correct the tuning through the mouth and the difficulty of sound production resulting from the morphology of the instrument (mainly the piston trombone gaps.The advantages are the easiness in the technical execution (for example, in certain trills) , the compactness, and the use of the same digitalization in all instruments (high, tenor, low) of the family of the metals family.
This trombone “of rollers” according to the designation used in the band of the artists of Funchalenses, is equipped with a system of 4 rotary valves in replacement of the pistons. It has a removable nozzle and its body is made up of two pieces – the first one includes the valves or the labels, and the support for the mouthpiece. The second in “u” ends with the bell.
