Solos and ensembles

In classical music the soprano, alto, tenor and bass - SATB - choir is a key part of church music, madrigals and opera choruses.

Choral music

Different types of choir include mixed choirs - usually with parts for SATB - male voice choirs, female choirs and a cappella ensembles.

A cappella ensembles are unaccompanied choruses. Ladysmith Black Mambazo are an a cappella Zulu male voice choir from South Africa. African songs are usually either strophic - split up into verses - or in call-and-response form.

In call-and-response form the leader sings a line - the call - and is answered by a chorus - the response. The chorus usually stays the same while the soloist improvises. There is often overlapping between the leader and the chorus. The chorus part is usually homophonic – in block chords.

Solo song

Different types of solo song include lieder, arias, ballads and folk songs.

The solo voice has been used in arias, solo songs and popular songs in all kinds of styles.


Lieder - pronounced leeder - are German art songs from the Romantic period - roughly the 19th century.


Arias are solo songs found in operas and oratorio.

An opera is a drama set to music, acted and sung by solo singers and accompanied by an orchestra.

One of the most famous operatic tenor arias is “Nessun Dorma” - No one shall sleep - from Puccini’s opera Turandot. This impassioned lyrical aria famously ends on a high sustained B. The voice is accompanied by orchestra and choir.

An oratorio is a setting of religious words for solo singers, chorus and orchestra. Unlike an opera, an oratorio is not staged. Messiah, by Handel, is the most popular oratorio.

Da capo arias were common in the 18th century. A da capo aria is where the voice returns to the head of the score (da capo) and repeats the first section of the music. It was common for the soloist to add ornamentation when the first section was repeated.

Vocal techniques

Different techniques are used to change the nature of the voice.


Vibrato is the pitch of the voice rapidly changing up and down. It gives notes warmth and richness. This technique is used a lot by opera singers.


When a male singer sings in the soprano or alto range he is singing falsetto. The voice type is known as countertenor.


Belting is when a singer uses their chest voice and pushes out the sound, often found in popular music and jazz. The effect can sometimes sound like shouting if not performed effectively.


Scat singing is a type of vocal improvisation using wordless or nonsense syllables. Ella Fitzgerald was known as a scat singer.


Rap is when an artist speaks words rhythmically and quickly over an instrumental or electronic backing.


This is when a voice imitates the sounds of a drum machine. Beatboxing is popular in hip-hop music.
