josh had this to say a while ago about chanters and I wanted to bring the discussion back to it
Chanters don't play music (or sing). That might not seem like a big deal, but everyone assumes otherwise. My hope was that calling them chanters would help distance them from bards, even if they occupy a somewhat similar mechanical role. Additionally, bards have a stigma of being stinky characters, mechanically. We do not want chanters to carry that stigma.
While ciphers are conceptually similar to psionicists, psionicists have had wildly different mechanics in D&D over the years, so there's not necessarily any common ground between them there. "Psionicist" is a really sci-fi sounding name, especially in D&D. Cipher is more a enigmatic name. In our lore, the first identified ciphers were a mystery to animancers because they couldn't figure out how they worked. The fact that these ciphers were also orlans, who are notoriously difficult to read, added to their mystique.
Basically a chanter:
The video reminded me of something that I am fairly well familiar with. Here is an example of real-life chanters that I know about and it'd be cool if different cultures/races/etc had different "chanting styles."
this dude is reciting a portion of Arabic text (yep, it's the Quran) for a group of people. He isn't singing or anything and a big part of good quranic recitation or incantation deals with the proper "pronounciation" and proper inflections and other rules that one must follow when reading the Quran. These aren't rules that are followed when speaking Arabic in daily activities. They are called "tajwid" rules and this dude is very famous for his "mad chanting skillz." The word al-Quran means the recitation in any case.
Here's another one. One thing that is measured is how good you are able to measure your breath when reading the Quran without reading too fast and at the same time following the recitation rules.
The background "ahhhhh" or "awwws" you hear are people praising him, basically.
Here's an interview he had. This dude is basically famous the world over and is a historical hero for many Muslims.
