The female vocal range is higher than that of a male singing voice. In choral music, the female voice is categorized on the basis of the singer’s vocal range and occupies the first two categories of the SATB (Soprano, Alto, Tenor, Bass) classification. In classical music, the female voice is divided into three categories.
Each category further subdivides into subcategories. These subcategories are characterized by voice qualities such as vocal range and weight, vocal timbre and tessitura, and passaggio or vocal transition points like vocal breaks and lifts. These voice qualities along with vocal register constitute the main criteria on classifying the female singers.
Some pedagogues include the “head voice,” “middle voice,” and the “chest voice” to the registers; however, the use of such “voice” is confusing and thus is not universally accepted. Musical pedagogues use these voice qualities as well as the vocal registry to determine and classify a person’s voice to a specific category. For female voice, there are three generally accepted categories, namely: soprano, mezzo-soprano, and the contralto.
The soprano is the highest singing voice and has the highest tessitura except for a specific type of soprano called the sopranino. It has the highest vocal range of two octaves that generally spans between the keys C4 and C6. C4 is the middle C key found at the center of a piano keyboard. This is divided into five subcategories according to vocal range, timbre, weight, and voice agility. These five subcategories are the following:
1) Coloratura Soprano
Coloratura Soprano is a type of soprano voice usually found in operas that is identified with agile runs and leaps as well as trills.
Soubrette is a soprano voice subcategory that lies between C4 to D6 that is characterized by lightness with sweet timbre and midrange tessitura distinctive of that frivolous, girlish character that the soubrette portrays.
3) Dramatic Soprano
Dramatic Soprano is characterized by a rich and powerful voice that is full of emotions that can ably cut through or sing over a full orchestra. It has a voice range that extends from A3 to C6.
4) Spinto Soprano
Spinto Soprano is a soprano subcategory with a voice range that spans from C4 to D6 that is depicted by voice clarity and easy handling of high notes. The spinto is characterized by the use of the singer’s “ping” or “squillo” to vocally slice through the orchestra similar to that of a dramatic soprano.
5) Lyric Soprano
Lyric Soprano has a similar vocal range to a soubrette but with full timbre and higher tessitura to differentiate it from soubrette.
The sopranino is a rare singing voice that occupies a higher vocal range than the soprano that lies between E4 to E6 but can be extended to A7. Although not part of classical or theatrical music, sopranino may perform as a regular soprano.
The mezzo-soprano is a singing voice that lies below the soprano but higher than contralto. This vocal category spans from A3—which is the A key below the middle C or C4—to A5. In many cases, the mezzo-soprano can extend down to F3 or up to C6. The mezzo-soprano is characterized by heavier and darker vocal tones than the soprano. Like the soprano, this vocal category is broken down into three subcategories namely: coloratura, lyric, and dramatic mezzo-sopranos.
The contralto is the lowest range of female singing voice found in classical and operatic music. This vocal category is relatively rare among vocal ranges and stretches from F3 up to F5 on the piano keyboard. Some contralto voices can be as low as E3 or as high as B♭5. Considering its various voice qualities and vocal register, this vocal category was further apportioned in the same manner as that of the mezzo-soprano voice category.
Contralto and its choral counterpart, alto, shares the same vocal range that spans from F3 to F5. This is where the association stops. Contralto and alto are not the same categories as classical categories, for the contralto was categorized by considering the vocal registers as well as other voice qualities aside from vocal range.
Contralto: The Lowest Female Singing Voice
So, what is the lowest female singing voice? The lowest singing voice widely acceptable is the contralto, and this is what this section will focus on.
Females are known for their unique voices, which turn many on whenever they hear them. The female singing voice is classified in different dimensions. The differences are evident in terms of range and voice. However, here, you will see the category based on the lowness or highness of the voice, with a specific concentration of the lowest singing voice of the females.
Vocal Characteristic of Contralto
Contralto is said to be the lowest singing voice that is typically identified with the female gender, and it is actually unique of all the voices traceable to the female. Most of the female voices are either soprano or mezzo-soprano voices, but contralto has brought a shard and distinct taxonomy in the categorizing of female voices. Contralto voice is in similitude with other voices like basses and countertenors in terms of lowness and rareness. And the amount of tessitura present in contralto is ranged between E3-ES with a laudable measure of vocal weight.
In the aspect of vocal range, contralto as the lowest voice is said to be reasonably rare. It is somewhat similar to, but different from that of alto, and kind of similar to the vocal codes of the countertenor’s voice.
Contralto Female singing voice is mostly found within the below F below the mid C to the second F that is the C above the middle C (F5). Some voices at some extreme points do hit the E3 that is, the E below the middle C. Concerning the range of the voice; it could be noted that contralto would be close to the male tenor voice and the female singers with the contralto singing voice would be able to sing some songs at the same range with the male singers sing tenor. In essence, contralto can transit out from the chest voice, which is around the E3 the E note that is found below the C located at the middle, shift the note D which is just a pitch or octave higher than the middle note C, where the head voice is found.
Contralto voice can further be categorized into three general types: coloratura, dramatic contralto, and lyrics. The relevance and understanding of contralto is primarily traceable to its afflation with the operatic and classical singing. This is based on the knowledge that classical singing in comparison to other traditions of higher capacity to accommodate more vocal categorization. The usage of contralto as the lowest female singing voice is also extended to the context of Jazz. In Jazz, contralto is used to describe the lowest female single voice. While in contemporary operatic context, the usage of contralto has been tied categorized more often as the mezzo-sopranos. This is rooted in the fact that the singers that fell within each range are known for their covering for singers in the aspect of other ranges.
Furthermore, there has been a different misconception in the usage of contralto and alto. Many people do misconstrue contralto for alto while referring to the female voice that falls within the low range of notes. While Contra alto refers to the low female lowest voice type, alto on the other side of the coin would mean, the notes or the range at which a singer sung. From above distinction, it would be crucial you note that the different is based on the former being a voice type and the latter being just a voice range and not a type per se. in Choral singing, for instance, the usage of alto is linked to the reference to the vocal parts in the alto section taken by the singers.
Finally, characteristically speaking, contra-alto differs from female voices. Contra alto is found to be darker and even richer in comparison to the mezzo-soprano. In terms of practice, a singer using a contralto female singing voice would be found flourishing in the land of outright convenience while placed on a pal with other singers using other female singing voices, because she is singing at the lower part of her voice.
