You want to play a duet scored for two flutes, but you have a flute and a sax.You have a flute-and-piano score, but you want to play the flute part with a sax.When is this a Problem?Įvery time you wish to play a score written for C instruments (like the flute or the piano) but you need to substitute one or more of the instruments with transposing instruments (like saxophones). Not all saxophones are in E-flat, though: The tenor and the soprano sax, for instance, are in B-flat.Īs you may already have guessed, on such an instrument the whole scale gets transposed: if a C sounds as an E-Flat, a D sounds as an F, an E sounds as a G and so on. That's why we say that the alto sax is a transposing instrument in E-flat. When an alto sax player plays a written C, his/her sax sounds an E-flat.When a flute player plays a written C, his/her flute sounds a C.The reason behind this is that the saxophone is a transposing instrument, while the flute is not. If the duet is scored for two flutes, trying to play it as it is would simply not work.
