If the purpose of Dulcimer Day is to introduce more people to the dulcimer, I vote for December 8 to commemorate Jean Ritchie's birthday. Here's why:
It's true December is a busy time that doesn't need more holidays. However, the dulcimer fits nicely into a lot of existing events that involve music and history. It's easy to get the general public interested in an evening of Christmas carols and folk music at this time of year. December 8 is early enough that most schools, clubs, community centers and park districts are still open, while special holiday events are always looking for music.
Jean Ritchie's life story connects us to the entire history of the dulcimer. From her family's musical roots in the 19th Century... to the folk revival... to the many people she inspired who make music today. She has gifted us with a story that explains the dulcimer in a way that is far more compelling than reciting the history of wooden boxes with strings. You could mention her in a few brief sentences or build the entire presentation around her, but either way you have a great starting point.
Jean is not well-known to the general public, but folk musicians know her. This could open the doors to music venues that otherwise don't often (or ever) feature dulcimers.
Let's face it, it's hard for a modern audience to feel a connection to anyone who died 100 years ago and didn't leave behind any video or audio recordings. The history can come later, but first we have to get people to listen. I don't want to make Dulcimer Day primarily about Kentucky, or the 19th Century, or our Scots-Irish ancestors way up in the hollows. That excludes so many people! Jean's music came from those roots, and then she brought the dulcimer to New York City and gave it to everybody. We can honor her roots and her courage to welcome all people, everywhere, to the music she loved.
Thinking of school presentations, Jean was a kind mentor and humanitarian who makes a wonderful role model. I would close by leading the kids in singing Jean's Peace Round. What could be better?
Or else, you know, talk me into something else :-)
