I took first place in the 1992 championships. Back then there were a small group of players that entered every year, so it was a matter of time before my number came up. Don't remember what I played but they would have been old time, and chorded. Also all of us entered multiple categories... not just dulcimer. There weren't very many people who only played one instrument back then. I haven't been to the ch'ships for at least 15 years.
I remember that the banjo and fiddle contestants got to do three numbers, then three more in the semi-finals, and three more in the finals. Other categories, like dulcimer, OT singing, guitar, etc., got to do one song (so it had better be a very long one).
