No offence taked Lep! Well, for one thing Oasis tends to use certain chords a lot, so I think it teaches beginners new chords other than the usual basic things. Favorite "Oasis chords" are: Em7, Cadd9, Dsus2, Asus4, Bsus4, and not to mention various chords with added basslines and variations. Keeps you on yer toes!They also use a lot of interest arpeggios that sound really cool, and when you learn them, it's tons of fun because YOU can play them now and they sound ever MORE cool!
