A concerto is a three-movement form of composition with a solo instrument playing alongside an orchestra. A concerto with many instruments playing in a " solo group " is called a concerto grosso.
A Solo Concerto is a concerto i which a single soloist is accompanied by an orchestra. It is the most frequent type of concerto. It originated in the Baroque Period (approx. 1600 - 1750) as an alternative to the traditional Concertino in a concerto grosso. Concerto = an instrumental work that maintains contrast between an orchestral ensemble and a smaller group or a solo instrument, or among various groups of an undivided orchestra. (fast-slow-fast) three movements. Concertino = The group of solo instruments in a concerto grosso. Concerto Grosso = a musical form, common in the Baroque period, in which contrasting sections are played by full orchestra and by a small group of soloists. Hope that helps :)
Typically a concerto grosso is for a small ensemble of solo instruments, rather than a soloist, with a regular orchestra. While concerti grossi were composed almost exclusively during the baroque period, a few composers in later periods, including our own, have written in the same form.
False. Vivaldi's Spring is an example of a Baroque solo concerto.
