Lesson plan
Split tone
Split tones are a multiphonic effect on brass instruments. During normal play, the upper and lower lips will vibrate together at the same speed. If, however, the lips are set to vibrate at different speeds, two pitches may be perceived. When not done intentionally, split tones are referred to pejoratively as "double buzzing".
