Above F1, a medial rotation and inward rocking of the arytenoid cartilages was observed, caused by the lateral cricothyroid muscles (LCAMs) and leading to inferior displacement of the vocal process of the arytenoid cartilage, and thus to further vocal fold stretching.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Trained singers achieve the first octave of pitch elevation by simple cricothyroid approximation. Further pitch elevation necessitates a complex movement of the arytenoids, first by CTM contraction and second by LCAM contraction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
