The girl must demonstrate her ability to entertain using music (singing or playing an instrument) and/or dance. Dance may be in any style: e.g. classical ballet, ballroom, or erotic. To be graded, the girl must perform in public, that is, in a full classroom. Private performances may not be graded. For higher grades, a girl should demonstrate diversity; making perhaps 3 or 4 performances of different types.
