Vocal Fry Register

The vocal fry register (also known as pulse register, laryngealisation, pulse phonation, creak, glottal fry, glottal rattle, glottal scrape or strohbass), is the lowest vocal register and is produced through a loose glottal closure which will permit air to bubble through slowly with a popping or rattling sound of a very low frequency. During this phonation the arytenoid cartilages in the larynx are drawn together which causes the vocal folds to compress rather tightly and become relatively slack and compact. This process forms a large and irregularly vibrating mass within the vocal folds that produces the characteristic low popping or rattling sound when air passes through the glottal closure. The very lowest part of the register can extend in rare cases to 20–50 pulses per second, or about two octaves below the lower part of the modal voice register (the normal voice).

    “The moon is nothing
    But a circumambulating aphrodisiac

    Carrying my father’s lean old leather case
    Crumbling like the register at the hotel....”
