The Singer must first and foremost learn the vocal parts to the music and be able to perform them at a high level. They must master many techniques beyond just singing the parts, for example proper microphone techniques, movement, and how to follow a Conductor. They also need to take good care of their voice, since their instrument is uniquely a part of their body. This means understanding issues that challenge vocal health and how to overcome them, as well as practicing proper breathing, posture, and other techniques related to producing a pleasing vocal sound without damaging the vocal cords.
