Careless Whisper (George Michael) played on gusli (baltic psaltery). Gusli is an ancient string instrument that has more than 1000 years of history. That's why it is all the time feeling like miracle to hear something modern played with gusli. Gusli has rather few strings, for example this one has only 11. There's no frets, and the whole string sound. So 11 strings means 11 notes only. That's the second reason why it is miracle to hear modern songs played on gusli. Otherwise it is the easiest professional string instrument to learn how to play ever! I can help you to join the small world's secret community of gusli players! :) You can order a gusli from me and I can teach you how to play! You'll need about 2-4 lessons to play your first songs.
