Potter surprises with duet arrangements of four Bach classics! Imagine the dense and dark Toccata and Fugue in D Minor played by a pair of flutes, and you begin to see the programming possibilities here. She also includes the Allegro movement from the Sonata in A Major, the Fugue from Overture in B Minor, and the Fugue in G Minor, all fascinating as flute duets. For flexibility, Falls House includes a substitute C flute part for Alto 1, and a substitute bass flute part for Alto 2.
