I’ve added links to a video class on event site heraldry to the East Kingdom Herald University page.
Crying announcements throughout a camp or other Society event location is a great entry point into voice work, with less formality than court heraldry, but it has its own challenges and “tricks of the trade” that are worth learning.
The class was taught by Ivo Blackhawk of Anstoerra, and may reflect a few small regional style differences from Eastern practice, but the vast majority of the material is directly applicable to any event here in our area as well, and it’s a useful addition to our curriculum.
