On the Subject of Relic Song

“When I feel a little sour, when I feel I got no power left...”

The module consists of a sheet music with a black clef-looking piece on its side.

This module has two Modes: one with the sheet music green and clef on the left, the other with the sheet music orange and clef on the right.

Every time a non-ignored module is solved, the current Mode can (but might not) change, and a series of 3-5 Notes will appear on the lines of the stave.

For every stage, record the Notes’ heights (the horizontal placement doesn’t matter) as well as the Mode they appear in, and apply the following rules for every Note:

• If a Note has appeared in both Modes, ignore both appearances as they Cancel each other out.
• If a Note appears multiple times in the same Mode without having been Canceled, ignore the duplicate appearances in this Mode.
• For both Modes, keep track of all Note heights that have appeared but have not been Canceled out nor ignored.

When all other non-ignored modules have been solved, the sheet music will show all five possible Note heights as empty circles, and the module can now be solved.

Input all Note heights that have appeared in the current Mode but have not been Canceled out nor ignored.
After inputting the correct Notes, press the clef to switch Mode.
Pressing a wrong Note or switching Mode without all expected Notes being pressed will result in a Strike.

Once both Modes have been filled with the correct Notes, press the clef once more to submit and solve the module.
