Vibration dampeners (also sometimes known as "gummies") may be interlaced in the proximal part of the string array, to reduce the percussive sound of the ball hitting the strings and/or to reduce perceived vibration. They do not, however, reduce impact shock significantly, so they are of no safety value.[13] Some professionals, such as Andrei Agassi, used rubber bands instead of specialized dampeners. Dampeners come in two main types. The first uses the two central main strings to hold it in place. The second is sometimes called a "worm" and it is woven between many of the main strings. Dampeners are nearly always placed very near the bottom of the racket string bed.

It wasn't until the 16th century that rackets came into use, and the game began to be called "tennis", from the French term tenez, which can be translated as "hold!", "receive!" or "take!", an interjection used as a call from the server to his opponent.[6] It was popular in England and France, although the game was only played indoors where the ball could be hit off the wall. Henry VIII of England was a big fan of this game, which is now known as real tennis.[7] During the 18th and early 19th centuries, as real tennis declined, new racket sports emerged in England.[8]

Writing for The Washington Post, Bethonie Butler observed a discrepancy between Lorde's statement that "In a perfect world, [she] would never do any interviews, and probably there would be one photo out there of [her]", and the fact that, in the music video, Lorde is "front and center."[73] Butler viewed the video as "a metaphor for celebrity."[73] Writing for Ryan Seacrest's website, Kathleen Perricone complimented the "super simple" clip, which allowed Lorde's "voice and lyrics [to] really shine."[71] Lindsay Zoladz, of Pitchfork Media, compared the video to that for The Replacements' "Bastards of Young" (1985).[74] MTV Buzzworthy blogger Luke O'Neil wrote that the "Tennis Court" video is "a bit unsettling at first, but eventually it starts to make sense. [Lorde is] trying to do things a bit differently, and so far it seems like it's working."[72]
There are many different types of string that tennis racquets come strung with but not all of them will be beneficial to your game. Less expensive tennis racquets have strings that are made out of material like nylon; these are basic strings and do not deaden the ball much as it hits the racquet or helps you to add spin to your shot. More expensive tennis racquets will you advanced synthetics are even strings made out of the internal parts of animals; these high-quality tennis strings will let you do more when you hit a tennis ball but will also sign up its price.One thing you have to keep in mind as far as a tennis racquet’s string goes is that you can always change it if you are dissatisfied with it. So do not stress too much if you are not sure which type of string you want on your new tennis racquet.

Regardless of the number of games and sets in a match, players must continuously rotate sides when the total number of games in a set is an odd number. For instance, if the total game score in a set is 3-2, simply add 3 + 2 = 5. Since 5 is an odd number, the players rotate sides prior to starting the next game. If the total game score in a set is 5-1, simply add 5 + 1 = 6. Since 6 is an even number, the players do not rotate sides.


The rules of modern tennis have changed little since the 1890s. Two exceptions are that from 1908 to 1961 the server had to keep one foot on the ground at all times, and the adoption of the tiebreak in the 1970s. A recent addition to professional tennis has been the adoption of electronic review technology coupled with a point-challenge system, which allows a player to contest the line call of a point, a system known as Hawk-Eye.
