This was taken straight from the Japanese Chrono Trigger sheet music book, so I'm 
positive this is right.

Repeat as many times as you want!

If there are any other songs from Chrono Trigger that you want to see,
message me and I will tab them out from the book.  
I'll do either guitar or bass tabs.
