I don't know how to notate the rhythm but here are the notes for the main riff, which I assume you mean the part that plays after the floaty/growling intro section drops out and then again during the "death on two legs....you're tearin me apart" chorus parts...
left hand does a strange chromatic pattern mostly between F# and B
B.....F# B A#...F# A....G#....D E F# G....E F#
right hand, on a higher register, hits an interval of B & D in steady quarter notes.
I imagine once you find the notes then the rhythmic pattern will come to you from familiarity.
hope that helps
billycat nearly got it right.
The main riff is played in octaves in the left hand and goes:
B.....F# B A#.F# A.....G#....B D F# G.D F#....
The right hand just plays repeated crotchets of a Bm chord, voiced as D F# B (low to high) with possibly another B below the D.
That comment by una999 was not only rude it was ignorant. Apparently he/she does not play an insturment and doesnt realise that notes from the guitar are the same notes on a piano and can easily be transfered over and onto most other instrument for that matter.
Thanks Bohardy! I admit, I just stumbled on my version of it while fooling around on the piano one day and never really confirmed how absolute my guesswork was. It felt right to me....but now as I play what you wrote I can hear the difference. suppose I spoke to soon. oh well, at least I was about 90% right...I tried :-P
as for how rude that one poster was...yeah, what a jerk! Though as for people saying how simple it is to transfer notes from a guitar to a piano I would have to argue that your assuming that every piano player should instantly have knowledge of the guitar and how the notes are set up on the neck. How do you figure? While I do the the notes on a guitar neck and can translate I still wouldn't call it a simple concept. Nearly every instrument uses the 12 tone scale but that doesn't automatically mean that when you see a slide trombone play something that you can instantly translate that to the sax.

(You'll even find "Was It All Worth It" in its entirety here - everything except the vocal score, for whatever reason.)

Most of the files should be accurate, especially high rated tabs on MySongBook. If not wholly accurate, they do serve as a good guide for figuring it out for yourself. The PTA used to be rated, but they removed all the tabs from the main site due to the whole MPA issue.
