Sight reading music is the ability to look at the musical symbols on a page and perform the music without any practice, or at first sight. A page of music can be intimidating if the symbols are unfamiliar. However, with practice any singer can begin to recognize the patterns on the page and learn how to create them with their voice.
Learning to read music will enable a singer to learn new music more quickly. It will also teach them how to communicate clearly with other musicians when collaborating at rehearsals and performances.
