Did you know?

An instrument is a tool, something used to construct. It's often a tool for making music. A musical saw happens to be a carpenter's tool that can be played with a violin bow (though you probably wouldn't want to play a wrench or a pair of pliers). The musical meanings of instrumental, as in "It starts with an instrumental piece" or "a jazz instrumental", are common. But the meanings "helpful", "useful", and "essential", as in "He was instrumental in getting my book published", are just as common.
