Like some others of you,I had to adapt after a hand injury.I discovered that chopping logs and drinking a whole bottle of Cinzano Bianco do not mix well,and now the end of my left index finger is part of my left palm !!At first it was dauntingly numb,but gradually,and with persistence,the feeling came back,and now I never think of it (nor do I drink Cinzano !).I never was any good at "barre" chords,so I have practised a lot at playing alternatives---I find Double Dropped-D tuning(with practice,and do I mean practice)gives me the sound,and the playing range,that I want for picking tunes from Hardy,Playford etc.,the sort of thing I like.
                   I generally get a tune in my head,and it just won't go away until I have spent some,or lots of,time just working out the fingering & picking,getting it right,then working on getting up to speed with it.It sounds obsessive ,I know,but that's how I 've always done it ! The last few weeks have been devoted to Merrily Kiss the Quaker and The Upton Stick Dance,but the obseesion is wearing off now,and I can relax a bit,until the next piece I fixate on !!
