Final answer:
The concerto genre gets its name from the Latin 'concertare', implying a musical contention or conversation between a soloist and an ensemble which is a hallmark of this musical form.
Step-by-step explanation:
The title of the concerto genre comes from the Latin verb concertare, which means "to contend with"or "to strive together." This musical form evolved during the Baroque period, where the typical structure involves a soloist or group of soloists playing in contrast with a larger ensemble. The dynamic between the soloist and the ensemble in a concerto displays a sort of musical contention, which is a conversational relationship and is a key characteristic that defines the genre.
