Lip sync, short for lip syncronisation, is a form of miming lyrics in sync with a song,without singing, to make it assume as if the song is being sang. Lip sync is most commonly used by Pop music artists, and has been criticised for the uses of lip syncing as it is unprofessional and can be easily noticed. 

Lip syncing does have many disadvantages to it, which makes it very unpopular and gives it a poor representation. Firstly, lip syncing doesn't show the talent that the music artist has, and is misleading to the audience, as the audience would assume that the musician is singing when they are not. Some music artists are in the music industry for the fame, publicity and money, and cannot actually sing, which is where lip syncing comes in handy. Lip syncing can also show the misattribution of vocals, where the voice of the music artist does not belong to them, but to another music artist who can sing. This gives the audience the false attribution, that the music artist can sing when they cannot.

However, lip syncing does have its advantages, in which it is commonly used by Pop artists who display high energy performances, where they are moving about the stage and cannot physically sing whilst moving about. Lip syncing can also be used to cover the singer's voice as of an illness or a problem affecting their voice, and lip syncing is also very beneficial to the music industry as it can save time, effort and money rather than having a music artist singing live.
