got 9000 by launching as close to the ground as i could with the power as high as i could. right before the plane hits, use 1 freaky, followed by 3 sodas. use the 3 skiis, followed by the other 2 freakys when needed.
just hit every note on guitar vs piano, 13215 but only gold. i know there was at least one note i didn't hold all the way =/ perfect score should be close to that.
like vadican said, it gets easier after dimension 12. it truly isnt that hard. i just found it extremely boring and suicided as soon as i hit 1 mil points for hard badge.
the locked guitars have special perks to them such as different animations when you hit the notes. and after 5x combo is x10 golden for those of you who were wondering
