If you asked me what a glass harmonica looked liked before I saw one, I definitely would not have guessed correctly. Or had any idea that they could create such beautiful, eerie tones. They are almost the opposite of modern harmonicas, a set of sleek water filled tubes that are used otherworldly, ethereal notes.
Glass harmonicas are not utilized often, but are famously used during the Mad Scene in the opera Lucia Di Lammermoor. The first video is an interview with glass harmonica player Sascha Reckert on the use and history of the instrument, and the second is a performance of the Mad Scene where you can see Sascha in action.
