Meaning of Labium in Music
In music, the term "labium" refers to a specific component of certain wind instruments, such as the recorder. The labium is the sharp front bottom edge of the window gap in the recorder's head joint. When air passes through the windway, towards the block, and into the labium, it interacts with the column of air inside the recorder, causing the stream of air to split and create vibrations both above and below the labium. This vibration is essential for producing sound in wind instruments like the recorder.
It's important to note that the term "labium" in music specifically refers to this component of wind instruments and should not be confused with other uses of the term, such as in anatomy (referring to the lips or labia) or medical conditions like labial hypertrophy .
