What is the range of a soprano voice?

The range of a soprano voice is typically defined as extending from middle C (C4) to A (A5) above the stave. This encompasses a higher tessitura that allows sopranos to sing a wide variety of repertoire, particularly in classical and choral music.

The zone outlined in the correct answer accurately reflects the characteristics of the soprano voice, as it can comfortably reach high notes above the treble clef staff, while also possessing the ability to sing lower notes that are still within the soprano range but not extending far into the lower register like a mezzo-soprano or alto might.

Understanding the range of a soprano voice is essential for composers and conductors to effectively write and arrange music suited to the voice type, ensuring vocalists can perform within their optimal range without straining.
