The members of the brass family are wound lengths of metal tubing with a cup-shaped mouthpiece at one end and a flared bell at the other. Pitch is controlled in part by the pressure of the lips and amount of air, and also by altering the length of tubing either by valves (trumpet, French horn, tuba) or by a sliding section of tube (trombone).

The percussion family encompasses a large and diverse group of instruments, which in the Western system of classification are divided into pitched and nonpitched. The nucleus of the orchestral percussion section consists of two, three, or four timpani, or kettledrums. Timpani are tuned to specific pitches by varying the tension on the head that is stretched over the brass bowl. The snare drum, bass drum, triangle, cymbals, marimba (or xylophone), tambourine, castanets, and chimes are among the other instruments found in the percussion section of an orchestra when called for in particular musical works. Percussionists usually specialize in a particular instrument but are expected to be competent players of them all.

The piano, harpsichord, and organ constitute a separate category of instruments. The harpsichord might be classified as a plucked string, the piano as both a string and a percussion instrument since its strings are struck by felt-covered hammers, and the organ as a wind instrument, its pipes being a collection of air-filled tubes. Because the mechanism of the keyboard allows the player to produce several tones at once, keyboard instruments have traditionally been treated as self-sufficient rather than as members of an orchestral section.

Counterparts to the Western orchestral instruments are found in musical cultures all over the world. Among the strings are the Indian sitar, the Japanese koto, the Russian balalaika, and the Spanish guitar. Oboe-type instruments are found throughout the Middle East and bamboo flutes occur across Asia and Latin America. Brass-like instruments include the long straight trumpets used by Tibetan monks and instruments made from animal horns and tusks, such as the Jewish shofar. Percussion instruments are probably the most numerous and diverse, from simple folk instruments like gourd rattles filled with pebbles, notched sticks rubbed together, and hollow log drums, to the huge tempered metal gongs of China, the bronze xylophones of Indonesia, and the tuned steel drums of the Caribbean.

Ensembles

The word “ensemble” comes from the French meaning “together” and is a broad concept that encompasses groupings of various constituencies and sizes. Ensembles can be made up of singers alone, instruments alone, singers and instruments together, two performers or hundreds. Ensemble performance is part of virtually every musical tradition. Examples of large ensembles are the symphony orchestra, marching band, jazz band, West Indian steel pan orchestra, Indonesia gamelan, African drum ensembles, chorus, and gospel choir. In such large groups, performers are usually divided into sections, each with its particular material or function. So, for example, all the tenors in a chorus sing the same music, and all the alto saxes in a jazz big band play the same part. Usually a conductor or lead performer is responsible for keeping everyone together.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
