Cristal Baschet

 

You might know it better as the theme tune to children's TV programme Picture Box, but in fact this is Manege, from Structures Sonores No4 by Lasry Baschet. It's played on the cristal baschet, or cristal as it's now known, an instrument that uses some of the same principles as the true glass harmonica, and which also approximates its otherworldly sound.
