The old actor behind the concert stage

Most performers will do some form of physical warm up. It really depends on what the performance involves. Stretches; loosening up, relaxation-type things.Those who are not moving a lot as part of their performance might also just do some energising work to wake up their body and have it “switched-on” for the performance. It also means that the body is ready to support the voice. Some speakers use motivational music to get energized and focused.
