Hi all, I'm trying to write a tab with guitar pro for this song:

Avantasia - Another Angel Down

No problems until it gets to the guitar solo. The first part is okay, but starting to 3:57 (refer to the youtube video) I can't figure out what frets are being used. Seems like a sort of tapping on a scale, I'm unable to continue

Can someone kindly help me a bit please?
