The Key Differences Between Contralto and Alto Voice: What’s an Alto Voice?

In classical music, both terms are used synonymously. For example, The New Harvard Dictionary of Music has this definition:

Alto [It.]. (1) A low female voice, also called contralto… (32)

However, in contemporary usage, they mean different things.

So, let’s look at altos first:

  • In SATB writing they perform the part between the sopranos and the tenors.
  • They have a conservative tessitura of G3 to C5 (see the Find Your Vocal Range in 1 Minute video).
  • In vocal ensembles, they’ll usually sing harmonies that support the overall sound while focusing on vocal blend.

Famous Altos:

  • Bonnie Raitt
  • Gladys Knight
  • Norah Jones

The Key Differences Between Contralto and Alto Voice: What’s a Contralto Voice?

True contraltos are the women who can sing the low notes:

  • It’s a rare vocal range, with only about five percent of women fitting this voice type.
  • They have a conservative range from F3 to B4 (see the Find Your Vocal Range in 1 Minute video), though many women can sing lower than that.
  • Also, the singing sweet spot is lower for them.

In addition, they can be a good fit for many different styles of music. The New Grove Dictionary of Music and Musicians states:

The versatility of such singers can be indicated by naming only three:

    • Ethel Waters: who moved from vaudeville and musical comedy to evangelical touring.
    • Ella Fitzgerald: whose extraordinary voice reached down to d and who competed with jazz instrumentalists in her “scat-singing” improvisations.
    • Marlene Dietrich: whose films roles made special use of her sultry and husky singing. (6:372)

Famous Contraltos:

  • Cher
  • Toni Braxton
  • Marian Anderson

Despite having somewhat similar ranges:

  • Also, contraltos can go low enough that they can be mistaken for tenors.
  • Normally, these singers are found in solo performance settings.
