I´m not a robot, but I´ve upvoted you as well :-) Really great article - and music of course! Your post reminded my on the time (some decades ago), when I was lecturing about the history of the piano, unearthing some really old instruments in muzeums and fighting to get the permission to play and record them. There were some Lyre-like instruments among the ancient predecessors of the piano as well. I´ll follow you right away. Have a great time! Rolf
