The term tutti originated in the 16th-century Italian language and literally means "all together." In music, it is used to indicate that all of the instruments or voices in a section are to play or sing at the same time. The opposite of tutti is soli, which indicates that only one instrument or voice is to play or sing.
Tutti is often used in orchestral music to create moments of great power and intensity. It can also be used to provide contrast to sections where only a few instruments or voices are playing. In jazz and other forms of improvised music, tutti sections can be used to allow all of the musicians to express themselves simultaneously.
The term tutti frutti has also been used in the titles of several popular songs and pieces of music, including the 1956 hit single by Little Richard and the 1963 album by Miles Davis.
