A concerto is a musical composition featuring a solo instrument accompanied by an orchestra. It is usually divided into movements (movements are like the chapters of a book) that often have different moods and tempos (the speed of the music.) A typical concerto has 3 movements, in a fast-slow-fast structure.
Here are two of my favorite violin concertos:
American violinist Joshua Bell plays the violin concerto by Ludwig van Beethoven with the Orpheus Chamber Orchestra. (The Beethoven is in three movements. They are titled 1. Allegro ma non troppo – this means, loosely, “Fast but not too much.” 2. Larghetto, which means “moderately slowly” and 3. Rondo which is a musical form where the melody comes back over and over again, alternating with other musical digressions.”)
Concertos have been written for lots of different instruments, not just the violin. Here is one of my favorite cello concertos, by the composer Edward Elgar with cellist, Jacqueline Du Pre.
