Okay, put ur capo on the 4th fret & design ur own picking pattern or just a simple strum is fine since
the voice that takes over the song.
C Am (Dm) G
Start with: There's a Hero....
There's an answer...
And then a Hero....
[ Tab from: https://www.guitartabs.cc/tabs/m/mariah_carey/hero_crd.html ]
do that progession all through until u hit the bridge when it modulates up approx 2.5 semi tones
if u wish, u can figure out the proper chords 4 this, but i just stick
with the C Am with the addition of a C & G change at the end of Don't let anyone
TEAR THEM AWAY & then just continue with the rest of the song as u will;)
Hope that helps!
