In music notation, a ligature is a graphic symbol that tells a musician to perform two or more notes in a single gesture, and on a single syllable. It was primarily used from around 800 to 1650 AD. Ligatures are characteristic of neumatic (chant) and mensural notation. The notation and meaning of ligatures has changed significantly throughout Western music history, and their precise interpretation is a continuing subject of debate among musicologists.
In surgery or medical procedure, a ligature consists of a piece of thread ( suture) tied around an anatomical structure, usually a blood vessel or another hollow structure (e.g. urethra) to shut it off. With a blood vessel the surgeon will clamp the vessel perpendicular to the axis of the artery or vein with a hemostat, then secure it by ligating it; i.e. using a piece of suture around it before dividing the structure and releasing the hemostat. It is different from a tourniquet in that the tourniquet will not be secured by knots and it can therefore be released/tightened at will.
The principle of ligation is attributed to Hippocrates and Galen, later reintroduced some 1,500 years later by Ambroise Paré, and finally it found its modern use in 1870–80, made popular by Jules-Émile Péan.
In orthodontics, a ligature is the small elastic band that is used to affix the archwire to the bracket. Ligatures are usually changed at each adjustment, and come in many varied colors including transparent. A series of ligatures connected to each other and used to pull teeth together with more strength is called a powerchain. Ligatures can also be made of wire.
Self ligation is a bracket that has a sliding or rotating mechanism to ligate an archwire. This type of bracket replaces elastic ligatures that are traditionally used. Self ligation typically cuts orthodontic appointment time drastically. Currently, self ligating brackets make up about 10 percent of total bracket sales worldwide.
A ligature is a device which holds a reed onto the mouthpiece of a single-reed instrument such as a saxophone or clarinet. The ligature must secure the reed firmly against the table of the mouthpiece while allowing it to vibrate freely. The earliest ligatures were lengths of string wrapped over the reed and tied. Iwan Müller invented a metal ligature to replace twine. String is still used by clarinetists, especially in Germany. Modern German mouthpieces have a groove cut into the outside of the mouthpiece to facilitate wrapping with a string ligature. Some modern clarinetists tie a shoestring around the mouthpiece to use as a ligature instead of a string because it is easier to tie. Other modern clarinetists use electrical tape as a ligature.
A ligature must be placed properly in order to allow best performance on a reed instrument. The ligature must be placed at least halfway down the stock of the reed and the screws must not be overtightened, in order to allow free vibration and not distort the reed.
Ligatures are most commonly made out of metal and plated in nickel, silver, or gold. Ligatures are also made out of wire, wire mesh, plastic, naugahyde, heavy nylon fabric, wood, string, or leather. Ligatures fall into two general categories, depending on whether the band contacts the reed or a pressure plate, either riding the band or adjusted inward from a block mounted on the band, using a thumbscrew, is used.
Various features are incorporated into the design of ligatures to hold the reed securely while minimizing pressure distortion of the reed and allowing maximum vibration. Contact rails may be either parallel or transverse to the reed, on either a metal band or pressure plate type ligature. The contact rails may be either metal, wood, or plastic. Pressure plates may also have raised contact points, prongs, or a concave form to control contact with the reed. Some bands are designed for minimal contact with the mouthpiece, allowing even less absorption of the reed's vibrations.
