<thinking>Let's approach this step-by-step:
Let us work through this systematically (CoT):

Step 1: What's the problem demanding me to do?
Calculate the number of character "z" in the string "Xylophone"

Step 2: Analyze the word.

Step 3: Oops, I made a mistake. The word I used above is incorrect. Let me correct that.
The correct word is "Xylophone", not "xyloptonb". I apologize for the error.

Step 4: Let's continue with the correct word. Spell out the word with numbered positions:

1. X
2. Y
3. L
4. O
5. P
6. H
7. O
8. N
9. E

Step 5: Locate the positions of the letter "z".
The letter "z" does not appear in the word.

Step 6: Enumerate the letters.
L: 1, P: 1, E: 1, Y: 1, X: 1, N: 1, H: 1, O: 2

Step 7: Assess the letters we tallied.
