Dm (xx0231@1)              FEchoes (133211@1)start as a cross in you,
G (320003@1)                     BbTrembling (x1333x@1)noises that come to soon.
Dm (xx0231@1)                     FSpatial (133211@1)movement which seems to you,
G (320003@1)                BbResonating (x1333x@1)your mask or feud.
Dm (xx0231@1)                  FHollow (133211@1)talking and hollow girl (Play a light D and E with the right hand),
G (320003@1)                    Bb (x1333x@1)

(Part with Cello:)

Em Dm G G/A Dm
And then you cut;
Em Dm G G/A Dm
You cut it out,
Em Dm G G/A Dm
And everything
Em Dm G G/A Bb
Goes back to the beginning.

Dm (xx0231@1)              FSilence (133211@1)seizes a cluttered room,
G (320003@1)                   BbLight (x1333x@1)is shed not a breath too soon.
Dm (xx0231@1)               FDarkness (133211@1)rises in all you do,
G (320003@1)                    BbStanding (x1333x@1)and drawn across the room.
Dm (xx0231@1)                  FSpatial (133211@1)movements are butterflies
G (320003@1)                    BbShadows (x1333x@1)scatter without a fire.

Dm (xx0231@1)               FThere's (133211@1)never been bad, there has always been truth,
G (320003@1)                   BbMuted (x1333x@1)whisper of the things she'll move.


Em Dm G G/A Dm
And then you cut;
Em Dm G G/A Dm
You cut it out.
Em Dm G G/A Dm
And everything
EmDm GG/A Bb (x1333x@1)           CGoes (x32010@1)back to the beginning.

(Big Instrumental Break - Play by the main chords of the verse)

Dm (xx0231@1)                             FNever (133211@1)said it was good, never said it was new,
G (320003@1)                     BbMuted (x1333x@1)whisper of the things you feel.
