Soprano flute

The soprano flute (also called a third flute or tierce flute) is a type of flute, a musical instrument in the woodwind family. It is pitched in E♭, a minor third above the concert flute, and is the only member of the modern flute family that is not pitched in C or G. The pitch was set at a time such flutes substituted for the E-flat clarinet, but the instrument is now rare.
