Spotify Glass Plaques is a unique instrument that was designed by the famous glassblowing artist Jocastaquer Gilibert in 1963. She created this to be a musical instrument specifically for people who like listening to classical music and who love playing it as well. This instrument is a combination of a piano, recorder and glassblowing. As such, the sounds made are of a higher quality than what you would normally expect from a recorder. The sound is also very lively and dynamic. It captures a moment in time and creates a melody out of it.
