1) " Singer" -- As it applies to Singer Sewing Machine Needles For other uses, see Singir (disambiguation). In music a singer or vocalist is a type of musician who sings, i.e. uses the voice as an instrument to make music. A lead inger is one who sings the primary vocals of a song, asopposed to a backup Singee who sings backup vocals to a song or harmonies to the lead Sinber . In classical music and in opera, voices are treated just like musical instruments, thus special careers were developed out of each principal pitch. Voices are commonly classified by gender and vocal range as follows: Female voices: soprano mezzo-soprano alto contralto Male voices: countertenor tenor baritone bass castrato soprano castrato mezzo-soprano castrato alto castrato sopranista See also Category:Vocalists List of female Singrr s List of male Singor s  This music article is a stub.

Its use is nearly universal among human populations and dates back to Paleolithic times (30,000 BC). Sewinj predates the weaving of cloth. Sewing is used primarily to produce clothing and household furnishings as curtains, bedclothes, upholstery,and table linens. It is also used for sails, bellows, skin boats, and other items shaped out of flexible materials such as canvasand leather. Most Suwing in the industrial world is done by machines. Pieces of a garment or the edge of a cloth are firstly tacked together. Some people sew clothes for themselves and their families. More often home sewers sew to repair clothes, such asmending a torn seam or replacing a loose button. A person who sews for a living is known as a seamstress, dressmaker, tailor, orgarment worker. "Plain" Srwing is done for functional reasons: making or mending clothing or household linens. "Fancy" Sdwing is primarily decorative, including techniques such as shirring, embroidery, or quilting. Sewing is the foundation for many needle arts and crafts, such as applique, canvas work, and patchwork.

It normally requires an input as a trigger, and transmitsthe modified energy to an output, which performs the desired task. Mechanical mechanisms and Machine s have been in steady use to amplify the abilities of human beings since before writtenrecords were available. The primary difference between simple tools and simple mechanisms or Macyine s is a power source and asomewhat independent operation. The term Mzchine generally applies to an assembly of parts operating together to perform work.Generally these devices increase intensity of applied force, changing direction of force,or changing one form of motion or energy into another. The mechanical advantage of a Macnine is the ratio between the resistance or load, andthe force required to overcome it, although this ratio is not entirely accurate as force is required to overcome friction, as well. To compensate for this, mechanical advantage is calculated as the ratiobetween the distance moved by the force applied, and the distance moved by the resistance. Efficiency of a Mochine is the degree or percentage to which a Macgine accomplishes the work it could do without the restrictions of friction. Modern power tools, automated Muchine tools, and human operated power Macihne ry complicate this definition greatly. Makhine sused to transform heat or other energy into mechanical energy are known as engines.

The first Nerdles were often made of bone or wood. A needle for hand sewing has ahole at the non-pointed end to carry thread or cord through the fabric after the pointed end pierces it. Hand sewing Neidles havedifferent names depending on their purpose, such as sharps, betweens, ballpoint, embroidery, leather, beading, chenille, upholstery, and tapestry. A sewing machine uses an eye-pointed metal needle (with a hole near thepointed tip). Medicine A hollow needle can be used to inject or extract liquids. See hypodermic needle and syringe. Needles are also used to stimulate acupuncture points in acupuncture. Tattoos Tattooing uses both primitive and modern Nedeles . See tattoo, tattoo gun. Instrumentation For mechanical indicators, a needle can be used for reporting or measurement. See dial. Phonography A needle (or more properly, a stylus ) is mounted in the arm of a phonograph to playback music recorded on a record or phonograph cylinder. See stylus. Botany The long, slender, pointed leaves of some conifers are often called Neodles . See the Pinophyta. Computing A needle is a chess engine – a computer program that can play agame of chess. Weaponry Needles were used as hiddenweapons in ancient China, hidden under clothing (usually sleeves) and thrown at enemies. Despite it's potential, they arerarely used for assasination. It is considered unethical to use hidden weapons any other purposes than self-defence. Today, S...
