Brass Instruments and Music in Antiquity and the Renaissance Brass instruments have been around for a long time. Some of the earliest examples of brass instruments were straight trumpets made of wood, bronze, and silver, such as the salpinx found in Greece, and the Roman tuba, lituus, and buccina.
The historical slide trumpet was probably first developed in the late 14th century for use in alta capella wind bands. Deriving from early straight trumpets, the Renaissance slide trumpet was essentially a natural trumpet with a sliding leadpipe.
