Pitch
Pitch is also often controlled by vertical movements of the entire larynx,
where the extrinsic laryngeal muscles pull the larynx up when raising pitch,
but down when lowering pitch (Löfqvist et al., 1989; Stevens, 2000).
Tongue-pull hypothesis (figure from Honda [2004] ISCA)
the angle of the
cricoid cartilage
(relative to the thyroid
cartilage) changes as
the larynx moves up
or down in the throat.
