Range refers to the vocal balance (muscle coordination) from the lowest to highest pitch.
Improving range is important because it will help you:
Vocal range is dependent on the coordination of the laryngeal muscles and the ability to transition between multiple registers.
The primary muscles needed to coordinate the tension and mass of the folds, along with access to multiple vocal registers, include:
Unlike measuring one’s range by how low and how high a singer can produce a pitch, “functional range” refers to one’s ability to produce pitches at multiple volumes, with multiple formants (vowels) and multiple intentional sounds (tone). Having dynamic and expressive choices on a given note is essential for self-expression and accurate interpretation of the lyrics and melody. Forcing a low note with an awkward tone and expression, or squeaking a high note with tension and stress, may allow a singer to reach the note, but it comes at a high cost: vocal fatigue, bad vocal habits and a disconnect with the audience.
Identify a song in which the singer demonstrates at least three different vocal registers. Identify the singer as well:
