Part Four is about modulation.
Ori reads the definition twice before attempting the first question. Modulation is the process of changing from one key to another within a piece of music. The module explains it with diagrams that make structural sense and with audio examples he listens to through his earphones, and he understands the concept the way you understand a concept before you have tested your understanding against actual questions.
Then he attempts the first question.
(Incorrect.)
He reads the diagram again. He listens to the audio example again. He attempts the question again.
(Incorrect. Review pivot chord theory before proceeding.)
He reads the pivot chord section. Pivot chords are chords that exist naturally in two different keys and function as the bridge between them. This is logical. He reads the explanation three times. He looks at the diagram. He listens to the example.
He attempts the first question a third time.
(Correct.)
He moves to the second question.
(Incorrect.)
This is how the next ninety minutes go.
Not every question requires three attempts. Some require two. A handful he gets right on the first try, the theory from Parts One through Three sitting underneath Part Four and occasionally surfacing to support it. But the modulation section is genuinely difficult in the way that things are genuinely difficult when they require not just understanding a new concept but integrating it with several previous ones simultaneously, holding multiple pieces of information in active relation to each other while applying them to a specific problem.
He does not give up on any question. He goes back to the relevant section, reads it again, identifies what he is missing, and attempts again. Sometimes this works on the second try. Sometimes it takes four. He completes every question before moving to the next one, which means his progress through the module is slow and his accuracy rate at the end of the first section is sixty-one percent, one point above the pass threshold.
He passes the section.
He moves to the second section, which covers enharmonic modulation.
By the end of the second section his accuracy has risen to sixty-nine percent. By the third it is seventy-four. The improvement is not dramatic but it is consistent, the curve of it moving in the correct direction with the reliability of something that is being built properly rather than rushed.
He completes Part Four at eleven forty-three.

He looks at the skill tree. The Music Theory node has shifted fully to amber. He is thirty points from unlocking it. He looks at his remaining tasks.
The audition piece. The recording.
He closes the theory module and opens his notebook to the second verse. He reads the problem line, the one that lands on the wrong beat. He has tried cutting it, rewriting it, restructuring the surrounding lines to accommodate it. None of the solutions have been clean.
He tries a different approach entirely: he reads the verse aloud, not singing it, just speaking it, following the natural spoken rhythm of the words without imposing a musical meter on them. He listens to where the emphasis falls naturally in the spoken version.
The problem line, spoken naturally, lands on a beat that is different from the one he has been trying to force it onto.
He has been fighting the line's natural rhythm instead of working with it.
He rewrites the surrounding structure to accommodate the natural emphasis rather than override it. He reads it back. The stumble is gone. The verse moves forward with the same momentum as the first verse, the two sections now matching in their forward pull.
He reads the full piece from the beginning for the first time in two days.
It holds.
Not perfectly. The bridge is still four lines too long and the final chorus repeat needs something in the last line that he has not found yet. But the structural problem is resolved and the piece has a shape now, a recognizable architecture, something that begins somewhere and ends somewhere else and knows the difference between those two places.
Kael knocks at twelve thirty.
He comes in with food from the corner place, two containers of something warm that he sets on the desk with the efficiency of someone on a schedule. He looks at Ori's face and the open notebook and reads the situation accurately.
"You fixed the verse," he says.
"I fixed the verse."
"Good." He hands Ori a container. "Eat first. Record after."
They eat. Kael talks about his morning, a lecture that ran long and a conversation with his project group that has reached a resolution of sorts, the drama Ori predicted settling into something workable. Ori listens and eats and the food is better than anything on the shelf beside the wardrobe by a significant margin.
When they finish, Kael moves to the desk chair. He takes out his phone.
"I'm going to record it," Ori says. "Not you."
"I know. I'm going to sit here." He puts the phone face down on the desk. "Do you need anything before you start."
Ori looks at the notebook. He looks at the small cleared space in the center of the room that he has identified as the performance space, the area without furniture that gives him enough room to stand and move slightly if movement happens. He thinks about what he is about to do, which is perform something he wrote about his own life in front of Kael, which is both the safest possible audience and, for reasons related to the specific intimacy of being known by someone, not entirely without cost.
"No," he says.
He sets his phone to record on the desk, angled toward the performance space. He opens the notebook to the full piece. He reads it once more silently.
He puts the notebook down.
He does not look at it again.
He performs from memory, which was not the plan but which happens anyway because the piece has been in him long enough that the words come without the page. His voice in the first verse is careful, managing itself, the technical awareness of the vocal exercises sitting on top of the naturalness and creating a slight friction. He notices this and does not correct it mid-performance because correcting it would make it worse.
In the second verse the friction reduces. His voice finds something closer to its own center, the place it comes from when it is not thinking about where it comes from.
By the chorus he is not managing anything.
He finishes.
The room is quiet.
Kael is looking at him with the expression he had the first time he heard the rough version, the one he described as allergies. He does not describe it as anything this time. He just looks at Ori with the honest and unperforming face and says nothing for a moment.
Then: "Play it back."
Ori picks up the phone. He plays the recording.
His voice comes out of the small speaker and he listens to it the way he listened to the video from Lecture Hall 3, with the dissociated attention of someone hearing themselves from the outside. But this time the difference is that he chose the thing being said. He chose every word of it and shaped them over five days and performed them just now without looking at the page.
The recording is not good in a technical sense. The pitch wavers in three places. The timing in the bridge is uneven. His voice in the first verse carries the friction he noticed, the management sitting visibly on top of the naturalness.
But in the second verse and the chorus something is happening that the technical issues do not cancel out. Something that the judges in the FLARE archive described as immediate. Something that makes Kael sit in the desk chair without speaking until the recording ends.
Ori stops the playback.
(Task complete. First self-recording reviewed. 30 SP awarded. Total: 100 SP.)

"Unlock Music Theory Level 1," Ori says.
(Unlocked. Remaining: 20 SP.)
He looks at the skill tree. The first Music node turns gold. The node above it becomes amber.
He looks at the recording on his phone.
"The first verse," he says.
"I know," Kael says.
"I'm managing it."
"You're managing it because you know I'm in the room. You stopped managing in the second verse because you forgot I was in the room." Kael leans forward in the chair. "The solution isn't to manage less. The solution is to forget the room sooner."
Ori looks at him.
"Twenty-three days," Kael says. "You'll forget the room sooner."
Ori looks at the phone. He looks at the notebook. He picks it up and looks at the bridge, the four lines too many, and begins cutting.
Outside, the Vaelmund afternoon does its ordinary work.
He cuts three lines from the bridge and reads the remainder.
Better.
