The whistle register (also commonly called the flageloet register) is the highest register of the human voice. It is typically used to produce pitches above E6. The ability to produce pitches in this register is believed to be rare. Physiology and definition The physiology of the whistle register is the most poorly understood of the vocal registers. It is known that when producing pitches in this register vibration occurs only in some anterior portion of the vocal folds. This shorter vibrating length naturally allows for easier production of high pitches. The physiological process that causes this is not currently known. Though the whistle register is most commonly used to produce pitches above E6, it can be used to produce lower pitches. By the physiological definition just detailed, it is a c
