I started playing my 5-string clawhammer style in a slow bluegrass jam session. I like bluegrass because it has a simple structure and there is singing. But as we move around the circle folks keep changing key to fit their vocal range. I have a hard enough time keeping my banjo in tune in one tuning, much less changing the tuning as the singer changes.

My goal is to backup the lead, and take breaks when it comes around to me. I think to path to improvising is practicing my scales, particularly the pentatonic scales. Before starting down that path I want to be able to settle on a versatile tuning.

I'm looking for suggestions for the most versatile tuning for playing clawhammer in a bluegrass jam session.

I would think G tuning would be best, because most bluegrass jams tend to stay between G and B more often than not. Learn how to play in C and D out of G tuning and you're good in most cases.

The B.G, goal is to play in any key out of standard G tuning. For ease of playing and also for more harmonious sound O.T./C.H. changes the tuning a lot for different keys. Your problem is an old one for banjos, that "damn" fifth string makes it difficult to change keys quickly, and especially in a circle where every player can and does change keys often. Some players "solve" this challenge with a long neck banjo a la Pete Seeger with a sliding fifth capo. Others have several banjos in different tunings. The one banjo that "does it all" is something of a unicorn myth in C.H.banjo world. I am not obsessed enough with scales and such to go the B.G. route. If the changing keys bugs you enough with the constant tuning/re-tuning you really could consider a tenor or plectrum banjo and use it just for that group. These choices depend upon what you want to do with your banjo(S). Good LUCK! banjered

Movable and Barr chords in open G tuning, with spikes on the 5th.

I’m in my 23rd year of banjo, after a background in guitar, and still have never learned any scales. Every thing I do is taken from chord forms, and if I can’t find what I want in one form, I’ll look for it in an inversion. Barr chords are full of hammer-ons and pull offs and sliding into and out of them have kept me busy for years.

I'm not sure there's a "one size fits all" approach. I played clawhammer at a BG jam and just flipped between G (gDGBD) and double C (gCGCD) tunings, using the capo as necessary. It's not perfect (but what is?), but it seemed to fit well. Plus, I got workouts (and experience) in both tunings. Besides, the banjo needs to be checked (and re-tuned) every so often anyway. It's just a matter of getting used to the extra effort.

I’ve been playing banjo since 1979, Scruggs style from then until about 4 years ago. I now only play clawhammer OT, it’s simple and you everyone sings and plays the same melody like Irish music.
I have never been in a bluegrass jam where they switched keys as you referenced. 99% was in the key of G.
Start your own jam, then you can shape it the way you want it to go.

After a few bar cords in a row my left hand says "no more>" Last summer the O.T. group got a wild hair up their behind and decided to go with "open key" from tune to tune. I brought an extra banjo but even with that i kept missing where the (damn) capos were and trying to keep track of what banjo was in what tuning for the next tuning for the next key. After a while I gave up and stopped going for a long time. They have finally surrendered and are now staying in one key for a while in deference to the (damn) banjo and that (damn) fifth string. That's my story and I am stuck to it! banjered

Welcome to the world of a Bluegrass banjo player! 

For G, A, Bb &B, tuning would be G tuning and 4 fifth string spikes at frets 7,8, 9 & 10

I might switch to dropped C tuning (4th string > C) for certain songs and tunes in C

C also works fine from open G, but playing C, F & G chords.

For D.E &F  I'd play from open G with the 5th spiked up +2 (that's what the spike at 10 is for)

Then I would recommend posting your question in the Bluegrass post.

After 60-plus years, including playing clawhammer in many bluegrass jams,Earlstanleycrowe’s advice is what I mostly do. But since I normally use standard C tuning, not double-C, I can quickly change tunings to play in D or E. Don’t overthink it. Stay based in G tuning.

Thanks for all the comments.

I guess this jam group is a little unusual in that it is mostly guitars and mandolins, a base, no fiddles, only one other banjo and that is only played occasionally.

I've read a lot about guitarists practicing pentatonic scales, but never from banjoists. So maybe that is a not a useful approach to improvising on the banjo.

And yes, I will try a tenor banjo in reentrant tuning dGBd for my next jam session.

RB-1 mentioned spikes. If you don't have 5th string spikes, get some installed. When you retune the 5th string up two frets to play in D, it throws all the other strings off, even if your capo doesn't. Only a slight retuning of the 5th is needed if you have 3 or 4 spikes put in. I play in both a BG and an OT jam. The two other banjo pickers in the OT jam take seemingly forever to retune from G to A or (god forbid) G to D. With spikes I can retune for new keys about 3 or 4 times faster.

The gDGBD works pretty well for playing more out of closed chord shapes.

I find myself using gEADE (or fDGCD) as versatile for many keys, and can quickly go from that to with just one (or poss 2) string change.
