"Old time fiddle uses a profusion of double stops and authentic players typically tune their instruments in "open tunings" or cross tunings. The set ups often include flattened bridges and in some cases no chin rest. The most popular tuning ia AEAE for the key of A, but the instrument can be down tuned to GDGD, which may put less tension on the neck when playing solo. ADAE is also popular for the key of D, and standard (GDAE) is often used for G. Some of the earliest popular repertoire includes "Turkey in the Straw," "Arkansas Traveler," "Billy in the Lowground." Accompanying instruments include washboard, jug bass, banjo, dulcimer, guitar, and occasionally kazoo."
not so much..at least what ive seen. generally people stay in standard tuning...and ive never seen anyone with a washboard or kazoo cept on beverly hillbillys. maybe all that for performance bands of paying customers at pigeon forge. The local jam and a few others in TN and NC are what i base that on. there was a bohdran player at an irish ession that broke out spoons once. you will hear more double stopping in old time vs irish. Not so sure about the flattened bridge thing either. that may be a thing somewhere or some time ago..but i havent heard anyone talk about doing it here. just fyi on what ive experienced outside the interwebs..small pond of fiddling but what ive seen.
@mouse even though it hasnt been common at this point for me..I really like the alternate tuning sound. You should investigate them and see what you like. I have one fiddle with helicores that sounds awesome tuned down GdGd and DDad. It would be nice if others on here that have been to places like clifftop or other events to share what theyve found in the way of jams and how alternate tunings are used. usually what happens is a jam will stay in a key for a while then switch. it makes it easier for banjos so ive been told. guitars just capo. durning that key switch ive never seen alot of retuning on the fiddles. Im sure its more common than im making it sound and the sound it gives is what i think alot associate with the old timey fiddle sound. but with you being more focused on solo play you dont have all that to worry about. Easier to experiment and spend time on it and not worry about learning things in a way that transfers back to a particular group of jam buddies.
I think trying to categorize too much or expecting past conversations to suffice for someones post of today..whenver TODAY may be is challenging. im more for just talk, do your best to find a similar section and roll with it. if things are repeated..so be it...it was interesting enough for someone to talk about again at any given time. someone else that has or hasnt talked about it may join in.
