Very interesting! Nice to see someone who does this kind of work. I 'play' at playing the guitar. If there's a need, I can add a little something. My calluses are kind of lame right now as I am a lead vocal and flautist for our band. Unfortunately, I haven't figured out how to play the flute and sing at the same time! If I do, I'll be sure to video it for the Steemit Community! Thanks for sharing! Upvoted and Re-Steemed!
