FOLK DANCES OF PUNJAB
The exuberance and vitality of the people of Punjab are vigorously displayed in their folk dances. The moves are full of expression, gestures, vocal remarks, subtleties of motion and uninhibited freedom – it is a dance from the heart! With the drum beat or to the tune of some other instrument of folk music, the energetic feet of the people of Punjab are spontaneously set to give into inhibition and give instant birth to a folk dance – an expression of the triumphant soul; an outburst of emotions; a sudden release of energy. The dances of Punjab are the clear depiction of the energy and enthusiasm of the lively youth of Punjab. The style of Punjabi dances ranges from very high energy to slow and reserved and there are specific styles for men and women. Some of the dances are secular while others are presented in religious contexts. The dances are typically performed at times of celebration, such as Harvest (Baisakhi), Weddings, Melas, like Lohri, Maghi etc., at which everyone is encouraged to dance. Married Punjabi couples usually dance together. The husband dances in the style of male Punjabi dances, frequently with arms raised and the wife dances in the style of female Punjabi dances.
The list of major folk dances of Punjab:
Bhangra
Originally, Punjabi’s performed Bhangra to celebrate the success of the harvest. Now people perform Bhangra
at wedding parties, receptions, birthdays, competitions and other happy occasions. In the villages, people
circle with large drums called dhols. Persons of all types of social classes perform Bhangra together. Even the
elders occasionally join the young to celebrate and dance Bhangra.
Giddha
Giddha is Punjabi’s most famous folk dance for women. In Giddha, the women enact verses called bolis, folk
poetry and dance. The subject matter of these bolis include everything from arguments with the father-in-law
to political affairs. The dance rhythm is set by the dhols and the distinctive hand claps of the dancers. These
days, people associate Giddha with Bhangra.
Jhumar
This dance, originally from Pakistan, is very much a part of Punjabi’s folk heritage. It is a graceful dance
based on a Jhumar rhythm. Dancers circle around the drummer and sing graceful lyrics as they dance.
Luddi
This is a victory dance where people do special movements of their hands. The costume is a simple loose
shirt. The dancers put one hand on their backs and the other hand in front of their faces. The body movement
is sinuous, snake-like. There is also a drummer in the center of the dance.
Dankara
Also called the Gatka Dance, this is a dance of celebration. Two men each holding colorful staves, in rhythm
with the drums dance round each other and tap their sticks together. This dance is often part of marriage
celebrations.
Julli
Muslim holymen, called Pirs, perform this dance. Generally they dance in their hermitages (Khangahs). People
perform the dance while sitting. Sometimes they dance around the preceptor’s grave. Normally the dancer
wears black.
Sammi
Traditionally women of the Sandhalbar region, now in Pakistan, perform Sammi. The dancers dress in bright
coloured kurtas and full flowing skirts called lehngas. A particular silver hair ornaments is associated with
this dance.
Dhamal
Similar to Bhangra, men dance in circle.
Jaago
Literally Jaago means wake up! When there is a marriage in the house, girls dance through the village streets
carrying a pot (gaggar) decorated with lightened candles and sing Jaago songs. The themes of the songs are
social and usually a bit of teasing, often aimed at elders, goes with the song.
Kikli
Women perform this dance in pairs. They cross their arms, hold each other’s hands and whirl around singing
folk songs. Sometimes four girls join hands to perform this dance.
Gatka
Gatka is a Sikh martial art in which people use swords, sticks and daggers. People believe that Guru
Hargobind Sahib started the art of Gatka after the martyrdom of fifth Sikh Guru, Guru Arjan Dev. Wherever
there is a large Khalsa Sikh population, there will be Gatka participants, which can consist of small children
and adults. These participants usually perform Gatka on special holidays such as Baisakhi and Gurpurb.
Musical Instruments in Punjab
Garah: The simple earthen pitcher serves as a musical instrument in a number of folk songs. The garah
player strikes its sides with rings worn on fingers of one hand and also plays on its open mouth with the other
hand to produce a distinct rhythmic beat.
Toomba: Toomba is a famous folk instrument of Punjab, which is entirely based on Iktara used by legend
singers. Now it’s been adopted by a number of Punjabi folk singers. Toomba is made of wooden sticks
mounted with a Toomba or wooden resonator covered with skin. A metallic string is passed on a resonator
over a bridge and tied to the key at the end of the stick. The string is struck with a finger or sometimes with
the Mizrab and the Swaras are made by pressing the string to the stick.
Dhol: Dhol is a favorite folk instrument of Punjab. It is a percussion instrument, which is used not only at
male dance performances but also during social rituals and festive celebrations. The drummer is called Dholi
and Bharaj. The dhol is a barrel-shaped wooden drum with a mounted skin on both sides. It is played with
two different types of wooden sticks. The skin on either side is tightened at a different pitch.
Dhad: Dhad is a small percussion instrument of the Damru style. Held in one hand, it is struck on either
side, with the other hand holding the skinned sides vertically or horizontally. This instrument has been very
popular with the Dhadies, who sing traditional ballads of brave warriors and heroes drawn from history.
Chimta: This is a percussion twang-type instrument used in Punjab and neighbouring areas. The tradition of
playing it with songs goes back to the Naths or Jogis. This instrument consists of two long, flat pieces of iron
with pointed ends and rings mounted on it. The joint is held in one hand, while the two parts are struck with
each other to produce tinkling sounds. Chimta has become popular in professional singing and devotional
music in temples.
Sarangi: Sarangi is a popular bowed instrument in Punjab. It is wooden instrument about two feet long, cut
from a single log covered with parchment. A bridge is placed in the middle. The sides of the Sarangi are
pinched so as to how it. The instrumental usually has three major strings of varying thickness and the fourth
string is made of brass, used for drone. Modern sarangis contain 35-40 sympathetic strings running under
the main strings. This is used for accompaniment by artists and is an ideal instrument for producing all types
of Gamks and Meens.
Bugdhu: This is a stringed instrument made of dried gourd (Ghia). A piece of skin is mounted on one side of
the hollowed gourd while the other side is kept open. A gut string (Tand) is crossed through the centre of the
skin and a small piece of wood is tied to the end of the string, which passes through the body of the gourd. To
maintain a drum-like rhythm, the string is stretched or loosened while playing.
Algoza: Algoza consists of a pair of wooden flutes. It is also called Jori (a pair) and is played by one person
using only three fingers on each side. Folk singers of Punjab use this in their traditional legend singing like
Mirza, Chhalla, Jugni etc. The instrument is also used as accompaniment with folk dances.

111 to 114 : Direction-Read the passages that follows. The questions at the end of teach passage are based on the content to the passage. Choose your answers from the choice mentioned.
The need for sola electricity is clear. It is safe, ecologically sound, efficient, continuously available, and it has no moving parts. The basic problem with the use of solar photovoltaic devices is economics, but until recently every little progress had been made towards the development of low-cost photovoltaic devices. The larger part of research funas has been devoted to study of single-crystal silicon solar cells, despite the evidence, including that of the leading manufacturing of crystalline silicon, that this technique holds little promise. The reason for this pattern is understandable and historical. Crystalline silicon is the active element in the very successful semi conductor industry and virtually all of the solid state devices contain silicon transistors and diodes. Crystalline silicon, however is particularly unsuitable to terrestrial solar cells.
Crystalline silicon solar cells work well and are successfully used in the space programme, where cost is not an issue. While single crystal silicon has been p proven in extraterrestrial use with efficiencies as high as 18% and other more expensive and scarce materials such as gallium arsenide can have even higher efficiencies, costs must be reduced by a factor of more than 100 to make them practical for commercial uses. Besides the fact that the starting crystalline silicon is expensive, 95% of it is wasted and does not appear in the final device. Recently there have been some imaginative attempts to make polycrystalline and ribbon silicon that are lower in cost than high quality single crystals; but to data the efficiencies of these apparently lower-cost arrays have been unacceptably small. Moreover, these materials are cheaper only because of the introduction of disordering in crystalline semiconductors, and disorder degrades the efficiency of crystalline solar cells.
The dilemma can be avoided by preparing completely disordered or amorphous materials Amorphous materials have disordered atomic structure as compared to crystalline materials, that is, they have only short-range order rather than the long-range periodicity of crystals. The advantage of amorphous solar cells are impressive. Whereas crystals can be grown as wafers about 4 inches in diameter, amorphous materials can be grown over large areas in a single process. Whereas crystalline silicon must be made 200 microns thick to absorb a sufficient amount of sun light for efficient energy conversion, only 1 micron of the proper amorphous materials is necessary. Crystalline silicon solar cells cost in excess of Rs. 100 per square foot, but amorphous films can be created at a cost of about 50 paise per square foot.
Although many scientists were aware of the very low cost of amorphous solar cells, they felt that they could never be manufactured with the efficiencies necessary to contribute significantly to the demand for electric power. This was based on a misconception about the feature which determines efficiency. For example, it is not the conductivity of the material in the dark that is relevant that only the photoconductivity, that is, the conductivity in the presence of sunlight. Already, solar cells with efficiencies will above 6% have been developed using amorphous materials and further research will doubtless find even less costly amorphous materials with higher efficiencies.
