Actually it sounds more like a Lute than a Harpsicord.

Still its an amazing achievement - a testimony to the power of "The Linux of kids toys" - LEGO.

And to think, with all the money he spent on Lego for this thing, he probably could have built himeself a Harpsicord and a baby Grand piano in wood for the same price!

I recall when at school, that one of the older students built an actual harpsicord in the woodwork classes over a number of years (about 4 I think) - he played it in front of the school assembly not long before he "graduated" from the school - it was amazing to see and hear.

Kind of invoke memories of that line from "It Ain't Half Hot Mum" along the lines of
"go play your harpsicord!"
