"Aura Lee" and "Dixie" are well-known tunes from the 19th century that still have popular appeal.  Legato playing is necessary for the proper interpretation of "Aura Lee," and "Dixie" should be played in a light but energetic staccato-marcato.  An excellent piece for concert of contest!  Versions for Woodwind Trio and Brass Trio are available from the publisher.
