String instrument
There are also plucked strings, the most famous of which would probably be the guitar. The guitar uses a fret board and a pick to pluck the strings while holding down on the fret board. It was made famous by rock groups like Led Zeppelin and artists like Eric Clapton. You play by strumming with one hand while choosing notes on the fret-board (string board) with the other. Banjos are also very similar.
