Vocal Types and Ranges | Music Appreciation 1 - https://courses.lumenlearning.com/suny-musicappreciationtheory/chapter/introduction/)
A voice type is a singing voice identified as having certain qualities or characteristics of vocal range, vocal weight, tessitura, vocal timbre, and vocal transition points, such as breaks and lifts within the voice. Voice classification is a tool for singers, composers, venues, and listeners to categorize vocal properties and to associate roles with voices.
Women are typically divided into three groups: soprano, mezzo-soprano, and contralto. Men are usually divided into four groups: countertenor, tenor, baritone, and bass. Some women fall into the tenor or baritone groups, while men identified as countertenors can be grouped as contralto, mezzo-soprano, or soprano. When considering the pre-pubescent voice, an eighth term, treble, is applied. Within each of these major categories, subcategories identify specific vocal qualities such as coloratura facility and vocal weight to differentiate between voices. The vocal range of classical performance covers about five octaves, from a low G1 (in scientific pitch notation) to a high G6. 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.
