armonicas
- Scope note
- Musical glasses developed by Benjamin Franklin around 1761, in which glass bowls of graded size fitted concentrically on a horizontal rod are turned by a crank attached to a pedal as the player rubs the rims with slightly moistened or chalk-dusted fingers to produce sound. In a slightly later development, a shallow trough of water is fitted below the rod, which is mounted obliquely so that the bowls are moistened as they rotate.
