“…The intensity of the
singer’s formant, the presence of vibrato, the maximum phonational
frequency range, and loudness increase with musical experience (e.g., Brown, Rothman, & Sapienza, 2000; Hunter, Svec, & Titze, 2006; Mendes, Rothman, Sapienza, & Brown,
2003). Yet, just a few isolated studies have focused on the mechanisms
underlying accurate pitch production in professional singers (Vurma & Ross, 2006; Zurbriggen, Fontenot, & Meyer, 2006). Zurbriggen and
collaborators (2006) asked expert singers to
