flutter-tonguing

Flutter-tonguing is a wind instrument tonguing technique. In this technique, performers flutter their tongue to make a characteristic "FrrrrrFrrrrr" sound. The effect varies according to the instrument and at what volume it is played, ranging from cooing sounds on a recorder to an effect similar to the growls used by jazz musicians.

== Notation == thumb|right|Tremolo notation In sheet music, the technique is usually indicated with the standard tremolo markings on a note alongside a text instruction to flutter the note. The German marking "Flatterzunge" is often abbreviated to "Flz." or "Flt.". The Italian "frullato" is sometimes abbreviated to "frull". In English, the most common indication is "f.t." Other markings that composers have used to indicate flutter tonguing include: coupe de lange roulé, en roulant la langue, tremolo dental, tremolo avec la langue, tremolo roulé, vibrata linguale, vibrando, and colpo di lingua among others. However, simply writing (3-line) tremolo marks on all rhythmic values without other indication is most generally accepted.
