A work for orchestra and solo instrument is called a concerto.
That depends, although sonata's are always for one or a very small group of instruments. Most commonly, piano solo, violin and piano, cello and piano, flute and piano, a wind instrument, a string instrument and a piano... It varies.. But its always a small ensemble.
A concerto is a work in three movements, rather than the four movements of a symphony, in which a solo instrument or ensemble is accompanied by an orchestra. The concerto developed earlier than the symphony. As in the symphony, the first movement of the classical concerto is generally in sonata-allegro form, followed by a slow movement and a finale usually in rondo form. The concerto had arisen in the Baroque period, in two types. One was the concerto grosso, in which a small ensemble within the orchestra is contrasted to and accompanied by the full complement. The other was the solo concerto as described.

first answer: Flutes are great for both solo and group performances. Flutes are Very Good for Solo, while at the same time work very well if you have a whole flute section in harmony. Flutes are also good on Group performances, because, the often have the melody of the piece of music with the trumpet.
There is no solo instrument; a brass band plays briefly.
