A Singer is a person who sings with their voice. Anyone who is singing is a singer. Some people do it as a job (professional singer), others may sing without being paid (amateur singer). Singers may sing anything: songs, opera, etc. They may be accompanied by an instrument or an orchestra. Some singers also play a musical instrument such as piano, guitar or harp while they sing (they accompany themselves). Singing is important in movies and in the theatre.
The lead vocalist (or lead singer) is the member of a band who sings the main solo vocal portions of a song. The lead vocalist may also play one or more instruments, and is usually the "leader" of their group, often the spokesperson in interviews and before the public. The lead vocalist is sometimes referred to as the frontman. For example, Jerry Garcia was the lead singer and frontman for the Grateful Dead.
A good singer will have to think of a lot of different things in a performance. Some attributes of singing skill are good vocal technique, a large vocal range, as well as feeling the song through emotional language and breathing, and also acting to provide a song with meaning. A good singer may be able to learn a song quickly, but it may take some time before they really feel it has become "part of them." A lead singer has to be a strong singer since background vocalists sing accompaniment.
Mongolian throat singing has become popular because due to its geographic location and culture. The open landscape of Tuva allows for the sounds to carry a great distance.
Singers can sing as a solo, or in a group or a choir. Choirs can include gospel music, church music and even pop songs where there are usually two male groups of singers (bass and tenor) and two female groups of singers (soprano and alto). Sopranos have a higher range and altos have a lower range. Combining these two can create various harmonies which add textures to songs and make them more interesting to listen to.
People may feel like singing for various reasons. They may want to share their feelings with other people. They may be feeling happy about something, or sad, or excited, frustrated or angry. Singing is an art in which mood is expressed through the voice.
