vibro- Also vibra-.
[Latin vibrare, to tremble or shake.]
The Latin word is the source of vibration, vibrant, and the musical term vibrato for a rapid, slight variation in pitch. A vibraphone (sometimes called a vibraharp, formerly a US proprietary name) is a percussion instrument containing a motor-driven rotating vane or electronic circuits that give a vibrato effect. A vibrometer is a device for measuring the movements of a vibrating body; the adjective vibrotactile refers to the perception of vibration through touch.
