Parts are:
I.Andante (attaca)
II.Adagio
III. Allegretto
First movement is "royal" in feeling.
Second movement? I think I can call it "Slow royal dance".
Third movement, allegretto it's just march, but in AABB+Coda form. Ends with three spectacular A's in lower strings.
Here are videos, made with program that gives amazing sounds.
