Singer
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.
