Drop contents:

• Page from Dr. Seuss "Oh Say Can You Say"

Page has guitar tabulature on the bottom.

e|------------------------|------------------------|-----------------------|-2-----4--2------------|-4----------------------| 

Low E = 1 (a zero on the low E string). That is the lowest note you can play on a guitar without changing the tuning.
Counting up by half step, starting with the low E, each note ends up translating to a number between 1 and 24 (E=1, F=2, Gb=3, G=4, Ab=5, A=6, ...).

Whole tabulature translates to:

9 19 20 8 9 19 20 8 9 14 7 15 14 3 8 5 3 11 15 14 5 

Each number matches up to a letter in the alphabet (1=a, 2=b, 3=c, up to 26=z). So the numbers translate to

Is this thing on check one
