'Conditions of a Solitary Bird': The first, that it flies to that which is highest -- The second, that it does not suffer companionship, even of its own kind -- The third, that it points its beak toward the sky -- The fourth, that it does not have a definite color -- The fifth, that it sings so sweetly.
'Sonata for Trombone and Piano': I. Allegro Maestoso -- II. Adagio -- III. Allegro Giocoso.
