Glass Armonica

Make crystalline sounds with spinning wet glass bowls—Mozart's favorite instrument

creativeintellectualcrafty$$$ high1 hourdifficulty 4/5

The glass armonica (or glass harmonica) is an 18th-century instrument that produces hauntingly beautiful tones by running wet fingers around the rims of nested glass bowls. Each bowl is tuned to a different note, and you play it by touching them as they spin. The ethereal, otherworldly sound has been featured in horror films and classical compositions. Benjamin Franklin popularized it in Europe, and Mozart and Beethoven composed pieces for it. Today it remains a sought-after instrument for ambient musicians and experimental composers.

    Research glass armonica basics and listen to recordings to understand the sound palette

    Practice basic scales and simple melodies to develop finger control and pressure sensitivity

Fun fact

The glass armonica was so popular in 18th-century Europe that some doctors believed it caused nervous disorders—one physician claimed the vibrations were 'dangerous to the nervous system.'
