What alot of people don't realize is that the diminished arpeggio is a very versatile subject.
A dominant 7th chord has a tension between the major third and the b7 of the tonic(diminished 5th). As a result, you can use the diminished scale over the b7 of the the chord to create a sort of b9 sound.
