Voice type to a high D6. Any individual's voice can perform over a range of one and a half to more than two octaves. Vocal ranges are grouped into overlapping types that each span about two octaves. Many singers fall between groups and can perform some parts in either type. Soprano range: The soprano is the highest singing voice. The typical soprano voice lies between C4 (middle C) and C6 ("high C"). The low extreme for sopranos is roughly A3 (just below middle C). Most soprano roles do not extend above C6 although there are several standard soprano roles that call for
