In practical terms, this means Arthur
Most of the process is Arthur actively creating music of some sort, that he can essentially use to harmonise with the people or general universe around him: he can use this to get an extremely rough gauge on a person's psychological state and any obvious influences that might be affecting them. From there he can use his music to magically influence the person or people he's in tune with.
Since this inspiration is being drawn from the Remedyverse, canon demonstrations of direct influence on people include:
》Rallying during battle [CotEG - Alan Wake]As Arthur is still completely new to these powers, he won't be able to use it for to their full potential, or even perform most of these immediately: most of his current focus is just on learning to control and understand it.
》Provide guidance through an otherwise unpassable area [TC - Control]
》Provide guidance through active eldritch fuckery [YY - AW2]
》Reinforce identity and return senses [HoD - AW2]
》Summon someone out of the Dark Place [DOS - AW2 (but still needs external assistance, eg Object of Power)]
When he starts leaning into the more proactively musical parts of these powers, hell eventually be able to do the following:
》Identify distinct timelines (as opposed to broadly discerning the same universe) pinpoint who is from the "original" canon line and who is divergent from it [canon basis in the known acknowledgement of the multiverse]But right now he's just fucking around and trying his best. Results will be extremely mixed and vary from thread to thread, as is the nature of a learning curve.
》Play any instrument with no prior knowledge whilst in the zone [Source: Pact of the Sword homebrew because it's funny]
》Summon instruments [source: mostly John Doe]
》Limited awareness of non-diagetic leitmotifs [source: Remedyverse's weird fucking meta layering]
