Within old time banjo, you've likely heard of 3 finger picking and 2 finger picking, but here is an example of ONE finger picking for your edification. I juxtapose one finger with clawhammer in the video.
The tune in the example is Angelina Baker, played in open G tuning, rather than the standard double D. It's actually easier to claw on banjo in open G. I never get above the 2nd fret in clawing the tune. So much for letting fiddlers pick the key!
Eric A , I'm with you. I do a peculiar down stroke bum-ditty. My fretting hand has most of the talent. Before the pandemic hit us, I went to a bluegrass jam every week with my dobro. I would occasionally claw some on the host's bluegrass banjo or bring on of my open backs.
