I used this nice Carolan’s tune to show my light system for harp. Now I can play in a dark, in a tea rooms with just a candle light, on medieval castles and I dont need to care if they light me properly on stage. (That was a big problem because in blue and red light some my strings become invisible) System is very easy and anybody can reach it simply, you just need LED light strip, few cheap parts (cable, joints, switch and two energy cources - one to socket and one for 12V battery pack - cost of one system is about 12 - 15 dolars) and of course your own hands and maybe some man’s help if you are girl :-) It’s possible to buy it in a harp shops, but I wanted to invent my own custom version and it’s always great satisfaction to complete task and make it on your own. :-)))
