Range

Alto and contralto are both female voice types, but they have different vocal ranges. An alto typically sings in the range of F3 to F5, while a contralto has a lower range, usually from E3 to E5. This means that contraltos have a deeper and richer tone compared to altos. Contraltos are often referred to as the "true altos" because of their ability to sing in the lower register with power and clarity.

Timbre

One of the key differences between alto and contralto singers is the timbre of their voices. Altos have a warmer and more mellow tone, while contraltos have a darker and more dramatic sound. Contraltos are often described as having a velvety quality to their voice, which adds depth and richness to their performances. Altos, on the other hand, have a smoother and more even tone that is well-suited for blending with other voices in choral settings.

Flexibility

When it comes to vocal flexibility, altos have an advantage over contraltos. Altos are able to navigate through different vocal registers with ease, making them versatile singers who can adapt to a variety of musical styles. Contraltos, on the other hand, may struggle with agility in the higher register due to their naturally lower vocal range. However, contraltos excel in the lower register, where their powerful and resonant voices shine.

Repertoire

Altos and contraltos often have different repertoire due to their vocal ranges and timbres. Altos are commonly featured in choral music, where their warm and mellow tones complement the higher voices of sopranos and tenors. Contraltos, on the other hand, are sought after for solo performances in opera and art song repertoire that require a darker and more dramatic sound. Contraltos are also well-suited for singing contralto roles in choral works, where their lower range adds depth and richness to the ensemble.

Training

Both alto and contralto singers undergo similar vocal training to develop their voices, but there are some differences in technique. Altos focus on expanding their vocal range and developing a smooth and even tone that blends well with other voices. Contraltos, on the other hand, work on strengthening their lower register and enhancing the depth and richness of their voice. Contraltos may also work on agility exercises to improve their flexibility in the higher register.

Roles

Altos and contraltos are often cast in different roles in musical theater and opera productions. Altos are typically cast as supporting characters or ensemble members, where their warm and mellow tones add depth to the overall sound. Contraltos, on the other hand, are often cast in leading roles that require a darker and more dramatic voice, such as the villain or the tragic heroine. Contraltos are also well-suited for playing male roles in opera, known as "trouser roles," where their lower range adds authenticity to the character.

Conclusion

In conclusion, alto and contralto singers have distinct attributes that set them apart in the world of vocal music. While altos have a warmer and more mellow tone with greater vocal flexibility, contraltos have a darker and more dramatic sound with a powerful lower register. Both voice types play important roles in choral music, opera, and musical theater, showcasing their unique qualities and contributing to the richness of the vocal landscape.
