[很]少 is often translated as "rarely'. 少 (the opposite of 多[meaning more]) means "less", so a rough translation would be "rarely" or more literal: "very less" i.e, 我很少吃早饭 (I rarely have breakfast).
Of course there are other words that come close to "rarely"
such as 不常(not often) 有时候(sometimes)
我不常听音乐 = I don't listen to music often.
我有时候喝咖啡 -I drink coffee sometimes
