METALLICA

Metallica is a American heavy metal band formed in 1981 from Los Angeles, California. Metallica was formed when the drummer Lars Ulrich posted an advertisement in a local newspaper, Metallica's line-up has primarily consisted of Ulrich, rhythm guitarist and vocalist James Hetfield and lead guitarist Kirk Hammett, while going through a number of bassists. Metalllica releases included fast tempos, instrumentals, and aggressive musicianship that placed them as one of the "big four" of the thrash metal subgenre alongside Slayer, Megadeth, and Anthrax during the genre's development into a popular style. The metallica releases heavy metal, thrash metal, hard rock and speed metal type of music. In 1986 release Master of Puppets

described as one of the most influential and "heavy" thrash metal albums.

Metallica band member are:

1. James Hetfield

trumpet

Trumpet are among the old musical instrument. The trumpet is the musical instrument with the highest register in the brass family. They are constructed of brass tubing bent twice into an oblong shape, and are played by blowing air through closed lips, producing a "buzzing" sound which starts a standing wave vibration in the air column inside the trumpet.

There are several types of trumpet; the most common is a transposing instrument pitched in B♭. The tube length of the most common B-trumpet is about 134 cm. The predecessors to trumpets did not have valves, but modern trumpets have either three piston valves or three rotary valves. Each valve increases the length of tubing when engaged, thereby lowering the pitch. The trumpet is used in many forms of music,

including classical music and jazz.

Piano

Piano is very popular instrument in the world. Piano is musical instrument and also know as a keyboard. Widely used in Classical music for solo performances, ensemble use, chamber music, and accompaniment, the piano is also very popular as an aid to composing and rehearsal.

but piano is more expensive and not portable. Beacuse of its versatility and ubiquity piano is most familiar musical instrument in the world.

Pressing a key on the piano's keyboard causes a felt-covered hammer to strike steel strings. The hammers rebound, allowing the strings to continue vibrating at their resonant frequency. These vibrations are transmitted through a bridge to a sounding board that couples the acoustic energy to the air so that it can be heard as sound. When the key is released, a damper stops the string's vibration. See the article on Piano key frequencies for a picture of the piano keyboard and the location of middle-C. Pianos are string instruments. According to the Hornbostel-Sachs method of music classification, they are grouped with chordophones.

Double Neck Guitar

Double neck (or, less commonly, "twin-neck") guitars enable guitarists to play guitar and bass guitar or, more commonly, a six-string and twelve-string. An early user was John McLaughlin, but the double-neck guitar was popularized by Jimmy Page, who used a custom-made Gibson EDS-1275 to perform the "Stairway to Heaven" and "The Song Remains the Same", although "Stairway to Heaven" was actually recorded using a Fender Telecaster. Don Felder also used the Gibson EDS-1275 during the Hotel California tour.

Semi-acoustic Guitar

These guitars have a hollow body and electronic pickups mounted on its body. They work in a similar way to solid body electric guitars except that because the hollow body also vibrates, the pickups convert a combination of string and body vibration into an electrical signal. A variant form, the semi-hollow body guitar, strikes a balance between the characteristics of solid-body and hollow-body guitars. Advocates of semi-hollow-body guitars argue that they have greater resonance and sustain than true solid-body guitars, as a solid wood body. Several metal bodies were made in the 1950s by violin and cello makers. In the 1970s, John Veleno made a polished aluminum guitar. Liquid Metal Guitars makes a metal body guitar made out of a solid block of aluminum and then chrome or gold-plates the instrument. Many guitars otherwise sold as solid-bodied instruments, such as the Gibson Les Paul or the PRS Singlecut, are built with "weight relief" holes bored into the body which affect the sound of the instrument. The Les Paul Supreme edition is currently described by the manufacturer as a "chambered" instrument, with a weight relief system designed to positively affect the sound.

Electric guitar Pickups

Compared to an acoustic guitar, which has a hollow body, electric guitars make comparatively little audible sound simply by having their strings plucked, and so electric guitars are normally plugged into a guitar amplifier, which makes the sound louder. When an electric guitar is strummed, the movement of the strings generates a very small electrical current in the magnetic pickups, which are magnets wrapped with coils of very fine wire. That current is then sent through a cable to a guitar amplifier. The current induced is proportional to such factors as the density of the string or the amount of movement over these pickups. That vibration is, in turn, affected by several factors, such as the composition and shape of the body.

Electric guitar

Electric guitar use the principle of electromagnetic induction to convert vibration of strings into electric signals. The generated signal without plugin in electric is to weak for a loudspeaker, it is amplified using a audio amplifier before sending it to loudspeaker. The signal can be modify by using effects such as reverb or distortion.

In the early 1930s, the electric guitar became a necessity as jazz musicians sought to amplify their sound. Since then, it has evolved into a stringed musical instrument capable of a multitude of sounds and styles. It served as a major proponent in the development of rock and roll, as well as countless other genres of music.
