Musical Score

Tsuzumi mansion

The drum demon started repeatedly striking his drums much faster then before as blood started running down into his right eye

(Y/n):*I can't keep up like this! I'm about to go blind from the blood! Keep your eye open!*

As (y/n) landed on the floor the blood ran down into his remaining eye causing him to close it, the drum demon struck his stomach twice

Two separate claw attacks began coming at (y/n) from different angles

(Y/n) was standing out back behind Tengen's mansion with the Sound Hashira following the meeting with Master Kagaya

(Y/n):what? The musical score technique?

Tengen:yes of course! The most important technique there is to sound breathing!

(Y/n):I understand! But...how does it work?

Tengen began smirking confidently

Tengen:it's the flashiest of techniques in our repertoire. One you'll have to master if you'll ever become a hashira like yours truly!

(Y/n):ri-right!

Tengen:most breathing arts have a special technique for finding openings in battle. But the Musical Score technique is by far the most difficult to learn and takes the longest to put into effect.

(Y/n):how does it work then, mr.uzui?

Tengen:well I'm glad you asked! When caught in a prolonged fight you'll eventually see more and more of what your opponent has to offer, by watching them and learning their patterns you'll be able to begin using the musical score technique.

He began posing

Tengen:the most simple way to describe it is, you break your opponents movements down into notes and turn them into a song!

(Y/n)'s jaw dropped

(Y/n):*only someone as great as mr.uzui could think of turning his opponents into a song! So flashy!*

Tengen:but don't get excited! The Musical Score Technique takes a long time just to grasp, it took me 2 whole months of nonstop training to figure it out. As I'm the first practitioner of sound breathing, the technique is new and likely has much room for growth. But once you've figured out your opponents rhythm there won't be much for them to do.

(Y/n):I understand! I won't let you down!

Tengen tossed a rag at him which (y/n) stumbled and caught

Tengen:the key to The Musical Score technique is sound, so you can do it even when impaired or in places you cannot see. The entire time we spend waiting for your final selection will be spent learning this technique

(Y/n):Right!

2 days before final selection

(Y/n) was standing in the forest behind the mansion blindfolded and covered with cuts and bruises
