air is gone. Then he sucks in with a deathly sound and begins the next movement. Movement four is based on the sounds of aboriginal tribes and the desert of Australia. It is essentially a long, virtuoso trombone solo played in imitation of the didgeridoo. The soloist plays a pedal B-flat, and sings an F, a twelfth higher. This, combined with different articulations, screams and occasional harmonic changes, creates a sound resembling didgeridoo. The movement ends with another gasp for air. Movement five is the finale. It begins with a slightly altered version of the "Crocodile Chorus", and recaps the various other movements of the piece. It ends with the soloist flutter tonguing a very loud note while spinning around in circles. This creates a sinusoidal sound effect, with a rising and falling volume. The soloist takes one last gasp for air and harmonizes with the orchestra on a final note that fades into silence. References Sandström, Jan.
