What does 'flutter tonguing' pertain to?

'Flutter tonguing' is a technique used predominantly by players of brass and woodwind instruments. This method involves rolling the tongue while blowing air into the instrument, creating a unique fluttering sound. It is often employed to add a particular expressive quality to the music, enhancing the overall texture and dynamics of a piece.

The reason this technique is specific to brass and woodwind players is due to the control they have over their breathing and articulation, which is essential to executing the fluttering effect effectively. While this technique is not applicable to string instruments or vocal performance, it stands out in wind instrument playing as a distinctive stylistic feature that contributes to various genres and musical expressions.
