strum

Imagine sitting around a campfire, with someone gently strumming a guitar while everyone sings along. That is the clearest picture of the word. It means to move your fingers or a pick across the strings of a guitar, ukulele, or similar instrument to make a rhythmic sound, usually by playing chords rather than single notes.

The word often suggests an easy, steady style of playing. A person might strum absentmindedly while thinking, or strum a few chords to accompany a song. In everyday English, this musical meaning covers most uses of the word.

To strum usually means to play a stringed instrument by brushing your fingers or a pick across the strings in a smooth, repeated motion. We most often use it for guitars, ukuleles, banjos, and similar instruments. Instead of picking out one note at a time, you are usually sounding several strings together, which gives a fuller and more rhythmic effect. If someone says, "He strummed a few chords on his guitar," the image is simple and familiar: a steady hand moving across the strings to support a song or create a relaxed musical mood.

The word often carries a casual, natural feeling. Someone might strum while singing, strum while waiting for other musicians to join in, or strum quietly when practicing at home. It does not always mean expert playing. In many contexts, it suggests an easy back-and-forth motion and a chord-based style rather than careful, note-by-note playing.

By extension, strum can sometimes be used more loosely for a similar sweeping motion across strings or string-like parts of an instrument, but the core idea stays the same: a light or rhythmic brushing movement that produces sound. This is why the word is strongly tied to musical instruments and is not normally used for ordinary touching or brushing in everyday English.
