The finale to the Concerto in G major is tuneful and fun to play!
As well as being a useful teaching resource, the two-flutes duet version (with 2nd flute part arranged by Roz Trubger) makes a good 'double concerto' item, that can be played with or without a piano or orchestral accompaniment.
The flute duet version comprises the flute solo plus the accompaniment compressed into a single line for a second flute player.
