willfly,its not quite the same as an autoharp,with an autoharp,the player can pickout a melody.
I find the attitude of this inventor insulting,he clearly doesnt understand that musicians,enjoy, learning to master their instruments.
part of the important thing for children ,is that learning an instrument,requires self discipline and perseverance,but the end result is pleasure and satisfaction at managing to play music.
this guys attitude typifies,the 21st century,everything must be produced instantly,at the click of a lever.
Personally I wish hed throw his contraption off the Twelve arch bridge in Ballydehob.
