There are many groups to match your many interests. Personally my own eyes lit up on "Dulcimer" as I'm now working on adding it to my storytelling programs. Do you know Friends of the Mountain Dulcimer? My only flute so far is Native American flute, but I recently bought a Middle Eastern flute and hope to add it as an intro and closing for Hodja tales. My guitar is sitting untouched these days, except for my acoustic bass guitar at jams, but since it's not a solo instrument I don't use it for storytelling. We have many who use music with storytelling here, but, so far, nobody has felt strongly enough the need for a group on that here to start one.
