Just in the past few days, ive had this craze for how cool the arpeggio scales sound. As of now I am working my fingers sore to try and practice some scales that other people have made (like the final fantasy song which is really cool by the way) and I've leaned only one scale itself, which is in A. I have a few questions that I would just love to have awnsered:

1) What is an arpeggio?
2) How do I figure them out for myself?
3) if it just a memory thing, scatch question 2, where can I find a page with all the different arpeggio scales?
4) is there more than one way to play an arpeggio in the same key?
5) isnt 4 enough?

thanks,
peace out, play on.
