In the song “Hungaria” there is a clear G major arpeggio and I discovered a interesting thing with the diminished scales over this chord.
First, take note of the G major arpeggio, played at the 10th postion, seen in this first segment below. Right next to this I show the three note 1,3,5 triad. Notice how well this triad pattern fits with the diminished scales below.

————-10-|———|-
———-12—-|———|-
——-12——-|———|-
—-12———-|—-9-12-|-
-10————-|-10——|-
—————-|———|-
Now, if you examine this G diminished pattern you can see the 1,3,5 triad pattern in the first 3 notes of it, which implies that this diminished pattern will fit pretty well over the major arpeggio above.

——————10-13-|-
—————12——-|-
———10-13———-|-
—-9-12—————-|-
-10———————|-
————————|-
Then finally, the G diminished inversion played 3 frets down, as usual, which shows more possibilities as an “approach” pattern to this G major arpeggio at the top.

————-7-10-|-
———–8——|-
——7-10——–|-
-6-9————–|-
——————|-
——————|-
This is just something I noticed. You may or may not get anything out of it. The key here is to run the G major arpeggio (with its approach notes) into the diminished pattern and then back, creating tension and release and a flowing feel in your solo.
