What Is a Contralto?
The contralto is the lowest standard female voice type — sitting below the mezzo-soprano and distinguished by an exceptionally dark, rich, chest-dominated tone throughout the range. The term comes from the Italian contra alto — "against the alto" — referring historically to the lowest part sung by women in early polyphony.
True contraltos are extraordinarily rare. Many female singers who believe they're contraltos are actually dramatic mezzo-sopranos. The distinction is tonal: a true contralto has a naturally dark, weighty quality throughout the range — not just in the low notes — combined with a relatively lower tessitura and passaggio.
Chest voice dominance throughout the range. Voice sounds full and resonant as low as E3–G3. Passaggio around A3–B3. Natural tone is consistently dark — not just on low notes. Very few females who think they're contraltos actually are — most are dramatic mezzos.
Contralto vs. Alto vs. Mezzo-Soprano
These three terms are frequently confused. Here's the distinction:
| Term | Context | Meaning |
|---|---|---|
| Alto | Choral/choir | The lower female choir part — sung by mezzos AND contraltos |
| Mezzo-Soprano | Solo/opera | Middle female voice — warm and flexible, tessitura B3–F5 |
| Contralto | Solo/opera | True lowest female voice — dark throughout, tessitura G3–C5 |
The critical point: most altos in choirs are actually mezzo-sopranos singing the lower part. True contraltos — with that characteristic depth and darkness throughout the entire range — are genuinely uncommon.
Many dramatic mezzo-sopranos are incorrectly called contraltos because their low notes are rich. The test is simple: does the voice have that dark, heavy quality throughout — including in the middle and upper range? Or does it only sound dark at the bottom? If the latter, you're almost certainly a dramatic mezzo, not a contralto.

Training Tips for Contraltos
- Your low register is a gift — protect it. Don't push upward into mezzo or soprano territory at the expense of your natural low resonance.
- Develop evenness across the range. The contralto's challenge is maintaining tonal quality as the range ascends — the upper range can go bright and thin.
- Handel and Bach are your foundation. The Baroque repertoire built on the contralto part develops line, breath, and tonal evenness magnificently.
- Avoid heavy chest pushing. True contralto depth comes from size and thickness of vocal folds — not from forcing. Pushing causes damage.
