Voice range
Voice range, also called tessitura, is the span of pitches a singer can produce comfortably, from their lowest sustainable note to their highest. It differs from person to person and defines which songs and exercises suit a given voice. Knowing your range lets a sight-singing tool present notes you can actually reach without straining.
Voice range describes the set of pitches you can sing cleanly and comfortably, bounded by your lowest and highest usable notes. It is closely related to tessitura, the part of the range where singing feels easiest and sounds best over sustained passages. Every voice is different, and ranges are traditionally grouped into broad categories such as soprano, alto, tenor and bass, though individual singers rarely fit a category exactly. Knowing your range matters because attempting notes far above or below it leads to strain, poor tone and possible vocal fatigue. In practice, singers warm up to find their reliable limits and then choose keys and exercises that stay within them. A sight-singing trainer that adapts to your voice range presents target notes you can actually reach, keeping practice productive rather than discouraging. FretMind's SingOnSight lets you set your voice range so the notes it asks you to sing stay within a comfortable, useful span while you build pitch accuracy.
