Tuning: Drop-Db (Db Ab Db Gb Bb Eb)

The opening is played purely by the symphony, but when the guitars come in, they

Db[-------------------------------------------]
Ab[---------------------------------------3-3-]
Db[-0-0-0-7--0--6--3-0-3--0-0-0-7--6-0-2--3-3-]

After playing that four times, both guitars then play:

Db[-0--0--0--6-7-6-5-0--0--0--6-7-X-X-]

Db[------------------------------]
