What range is designated for mezzo-sopranos in four-part harmony?

The range designated for mezzo-sopranos in four-part harmony is typically A3 to F5. This range is characterized by its comfortable tessitura where mezzo-sopranos can sing expressively and with a rich tone. Mezzo-sopranos are known for their ability to blend well with other voices in harmony, and the A3 to F5 range allows them to support the musical textures created in an ensemble setting while bringing their unique timbre to the group.

Other ranges listed in the options may overlap with different voice types, such as soprano or alto, but they do not accurately represent the standard range for mezzo-sopranos, which is consistently regarded within the A3 to F5 framework in four-part harmony settings. Understanding this helps in vocal categorization and arranging music appropriately for ensemble performances.
