locking and popping

Popping is a dance style and one of the original funk stylesof dance that is thought to have come from freshnoCalifornia during the 1960s-70s. It is based on the technique of quickly contracting and relaxing muscles to cause a jerk in the dancer's body, referred to as a pop, tick or a hit. This is done continuously to the rhythm of a song in combination with various movements and poses.Popping is also used as an umbrella term to refer to a group of closely related illusionary dance styles and techniques that are often integrated with popping to create a more varied performance, but it is distinct from breaking, with which popping is often confused. A popping dancer is commonly referred to as a popper.
When used as a hip hop dance style, popping is usually performed in a battle (also known as a competitive jam where participants try to outperform each other in front of a crowd. This gives room for improvisation and the performance of moves that are seldom seen in shows and performances (also referred to as freestyling). As a street dance it also encourages the dancer to interact with the other dancers and spectators.

Locking (originally Campbellocking) is a style of funk dance, which is today also associated with hip hop. The name is based on the concept of locking movements, which basically means freezing from a fast movement and "locking" in a certain position, holding that position for a short while and then continuing in the same speed as before. It relies on fast and distinct arm and hand movements combined with more relaxed hips and legs. The movements are generally large and exaggerated, and often very rhythmic and tightly synced with the music. Locking is quite performance oriented, often interacting with the audience by smiling or giving them a high five, and some moves are quite comical in nature. A dancer who performs locking is called a locker. Lockers commonly use a distinctive dress style, such as colorful clothing with stripes and suspenders.

Locking was originally danced to traditional funk music, such as that produced or performed by James Brown. Funk music is still commonly favored by locking dancers, and used by many competitions such as the locking division of Juste Debout. Locking movements create a strong contrast towards the many fast moves that are otherwise performed quite continuously, combined with mime style performance and acting towards the audience and other dancers. Locking includes quite a lot of acrobatics and physically demanding moves, such as landing on one's knees and the split. These moves often require knee protection of some sort.
