Trop is Rabbinic
This short paper introduces trop. Stating that trop is rabbinic may appear unnecessary. However, given that this is disputed, with some attributing a more robust position to the Karaites, it is nice to preliminarily demonstrate otherwise.
One possible counter-example I noticed while in Shul during leining, an ancient custom from the pre-COVID-19 era is Shemot (23:2.) Why I believe it is not is in a separate post. Other such examples are welcome.
