This has nothing to do with a personal desire to self-harm, being a reformed alcoholic or druggie, nor even being maudlin, but I heard Johnny Cash performing 'Hurt' a few days ago (Johnny Vegas on Desert Island Discs) and now have the tune lodged in my head. I think, from the German, this is an 'ear-worm.'
(Earworm, a loan translation of the German Ohrwurm, is a portion of a song or other music that repeats compulsively within one's mind, put colloquially as "music being stuck in one's head." ) Wikipedia.
A few moving YouTube clips, then I'm off to MusicNotes to download the sheet music. This tool is magic, it plays the tune karoake style and allows you to transpose the song at a click of a button. As a result after six months not touching the thing my guitar is having an outing and the pads of my fingers on my left hand are burning. (Metal stringed acoustic guitar). Finger-nails on my right hand suitably long and ready for action. Its a three-chord song. To get it exactly right another website runs through the precise order to pluck the strings. It'll take a little while to crack, as I'm rusty, but I'll do it. I love to relax this way.
Are the pads of my finger-tips getting fatter? I've never had such a problem keeping them on one string before. I may have to turn to a cat-gut strung classical guitar with a wider bridge.
Ho hum. Hum.
Alternatively I can ditch the guitar and get a friend who used to be a professional musician to play his. Team work. Theme of the week.
