The sackbut replaced the slide trumpet in the 15th century alta capella wind bands that were common in towns throughout Europe playing courtly dance music. See Waits.
Another key use of the trombone was in ceremonies, in conjunction with the trumpet. In many towns in Germany and Northern Italy, 'piffari' bands were employed by local governments throughout the 16th century to give regular concerts in public squares and would lead processions for festivals. Piffari usually contained a mix of wind, brass and percussion instruments and sometimes viols.[18]
Venice's doge had his own piffari company and they gave an hour-long concert in the Piazza each day, as well as sometimes performing for services in St. Mark's. Each of the six confraternities in Venice also had their own independent piffari groups too, which would all play at a lavish procession on the feast of Corpus Domini. These groups are in addition to the musicians employed by St. Mark's to play in the balconies with the choir (the piffari would play on the main level).[18]
It also was used in church music both for instrumental service music and as a doubling instrument for choral music. The treble and high alto parts were most often played by cornetts or shawms, with the violin sometimes replacing the cornett in 17th century Italian music.[18]
The first record of trombones being used in churches was in Innsbruck 1503. Seville Cathedral's records show employment of trombonists in 1526, followed by several other Spanish cathedrals during the 16th century, used not only for ceremonial music and processionals, but also for accompaniment of the liturgical texts as well, doubling voices.[19]
The sacred use of trombones was brought to a fine art by the Andrea Gabrieli, Giovanni Gabrieli and their contemporaries c.1570-1620 Venice and there is also evidence of trombonists being employed in churches and cathedrals in Italy at times during the second half of the 16th century in Bologna, Rome, Padua, Mantua and Modena.[19]
Since ensembles had flexible instrumentation at this time, there is relatively little music before Giovanni Gabrieli's publication Symphoniae sacrae (1597) that specifically mentions trombones. The only example currently known is the music by Francesco Corteccia for the Medici wedding 1539.[20]
