just learned that song this week was practicing it last night.
seriously though, ween urself off the tabs. they stunt you as a player. and writing them are time consuming, so i'll write out something.
basically its
1(Db) - 3(F) - 4(F#) - 4(F#) - 5(Ab)
(instead of the 2nd F# you can hit the 7(C) also. i alternate for variety)
except for that "we worship you o' lord" that goes down its
6(Bb) - 5(Ab) - 4(F#) - 5(Ab) - 3(F)
the "singing our song" part is
5(Ab) - 6(Bb) - b7(B) - 7(C)
5(Ab) - 6(Bb) - b7(B) - 7(C)
1(Db) - 2(Eb) - b3(E) - 3(F)
1(Db) - 2(Eb) - b3(E) - 3(F)
thats done twice. slide into the first note or something to keep it from sounding bland since ur holding that first note.
hope that helps
