Similar to what several researchers in the early 1980s dubbed “sonance,” quality comprises more than just timbre, including also intensity, harmonic spectrum, phonation, and changes in sound. Multiple dimensions—including timbre, phonation, onset, resonance, clarity, paralinguistic effects, and loudness—create a singer’s individual vocal quality. Songs recorded and re-recorded by Lucas Silveira demonstrate the dynamic aspects associated with an ever-evolving vocal quality due to the artist’s having undergone hormone replacement therapy. The concept of quality is framed in terms of three different orientations—the physiological, acoustic, and perceptual—all of which are essential to understanding qualitative aspects of vocal delivery, more so than aspects in the domains of pitch and prosody. While sonic markers of identities are fluid social constructions rather than static essential attributes, this chapter considers how qualitative elements may signify artists’ identities and genre.
