Alto recorder

The alto recorder in F, also known as a treble (and, historically, as consort flute and common flute) is a member of the recorder family. Up until the 17th century the alto instrument was normally in G4 instead of F4 (, (ii) Renaissance; , 50). The alto is between the soprano and tenor in size, and is correspondingly intermediate in pitch. It has the same general shape as a soprano, but is approximately 50% larger in all dimensions. A 50% increase in length causes a 50% increase in the wavelength for a given fingering. This lowers the pitch by a perfect fifth, that is from C to F.
