In musical terminology, tempo (time in Italian; plural: tempi )  is the speed or pace of a given piece. In classical music, tempo is usually indicated with an instruction at the start of a piece (often using conventional Italian terms). Tempo is usually measured in by beats per minute (BPM).
A pair of cheerleading pom-poms. A pom-pom â also spelled pom-pon, pompom or pompon â is a loose, fluffy, decorative ball or tuft of fibrous material. Pom-poms may come in many colors, sizes, and varieties and are made from a wide array of materials, including wool, cotton, paper, plastic, and occasionally feathers.
Pom-poms are shaken by cheerleaders, pom or dance teams, and sports fans during spectator sports. Small decorative pom-poms may be attached to clothing; these are sometimes called toories or bobbles. Pom-pom is derived from the French word pompon, which refers to a small decorative ball made of fabric or feathers.
