SOBRE LA EMISORA
The trumpet repertoire consists of solo literature and orchestral or, more commonly, band parts written for the trumpet. Tracings its origins to 1500 BC, the trumpet is a musical instrument with the highest register in the brass family. There are several types of trumpet. The most common is a transposing instrument pitched in B♭ with a tubing length of about 148 cm. Earlier trumpets did not have valves, but modern instruments generally have either three piston valves or, more rarely, three rotary valves. Each valve increases the length of tubing when engaged, thereby lowering the pitch.
