I put together a solo guitar arrangement for Edelweiss by Rodgers and Hammerstein (1959). I tried to keep it simple and pure because it's that type of song. I don't think flashy guitar work suits it because it's supposedly modelled on an Austrian folk song even though in actual fact it was written by Richard Rodgers and isn't an Austrian folk song at all I also put in a string trio for a backing and sang the last verse although I didn't bother videoing me singing - that doesn't add much either - I'm no singer. I believe Chet Atkins would often sing to his own arrangements while he was working them out to keep them honest and 'hummable' - it also helps to keep the tempo original. If people can hum along to your solo guitar arrangement I think that's a positive.
