Hi all, it's time for the new orchestration challenge already!
Since last time Randy (Bowser) offered a whole-tone theme I want to post a theme based on the diminished scale, built alternating a whole-tone and a half-tone. In this case it's a c# dim. scale (C#-D#-E-F#-G-A-Bb-C).
As usual you can do whatever you like with the given melody, as long as it is heard at least once in the piece and is substantially recognizable.
Good work everybody!
