Meanings
Originally mid-19th century slang with (usually pejorative) reference to the difficulty of leaving a well-worn rut (see in a rut). As back in the groove, the phrase acquired a positive sense of returning to one's usual self after a period of illness, setbacks, &c. With special regard for music, originally 1920s US jazz slang, possibly with reference to the grooves of early records.
Running or performing extremely smoothly, especially playing perfectly, perfectly in sync with others, or with perfect focus.
Used other than figuratively or idiomatically: see in, groove.
