Requiem

Notes:

• Move the cursor to the edges of the screen to move the camera.
• The button that appears on the second instrument is interactable.

How to read tablature:

• Each line represents a string. The bottom line is the left-most string and the top is the right-most.
• Dots on a line represent a note, read the tablature from left to right.

Still stuck? This is a super hard puzzle because I didn't have very long to work on it :,) Here are some hints:

(Note: the order of instruments / strings is left to right)

• Go to the second instrument. Click on it, and then click on the third string. Click the button that appears on the screen.
• Investigate the other instruments, look for symbols. The lines below the fingerboard represent an order, while the dots on the fingerboard represent what string to play. Take note of these symbols.
• Go to the last instrument, click the strings in the order from the symbols.
• Return to the first instrument and play the tablature you received by correctly completing the previous step. (See the section above on how to read the tablature)
