Flutter tonguing is one of the most widely-used extended techniques, dating back to the works of Richard Strauss. Flutists should be familiar with and be able to execute the two different types of flutter tonguing: one produced with the tongue, and the other with the throat. More and more commonly, composers will specify the type of flutter-tonguing to be used in a given passage. In the following example from James Romig's Oiseau Miró, individual and small groups of flutter-tongued notes are highlighted within a dense musical surface.
