The music and dance styles of Bangladesh may be divided into three categories: classical, folk, and modern.
The classical style has been influenced by other prevalent classical forms of music and dances of the Indian subcontinent and, accordingly, show some influenced dance forms like Bharatnatyam and Kathak.
Several dancing styles in vogue in the northeastern part of the Indian subcontinent, like Manipuri and Santhali dances, are practised, but Bangladesh has developed its own distinct dancing styles. Bangladesh has a rich tradition of folk songs, with lyrics rooted in vibrant tradition and spirituality, mysticism, and devotion. Such folk songs revolve around other themes, including love. The most prevalent folk songs and music traditions include Bhatiali, Baul, Marfati, Murshidi, and Bhawaiya. Lyricists like Lalon Shah, Hason Raja, Kangal Harinath, Romesh Shill, Abbas Uddin, and many unknown anonymous lyricists have enriched the tradition of folk songs of Bangladesh.
In a relatively modern context, Robindro Shongit and Nazrul Giti form precious cultural heritage of Bangladesh. Recently, western influences have given rise to quality rock bands, particularly in urban centres like Dhaka. Several musical instruments, some of them indigenous, are used in Bangladesh, and major musical instruments used are the bamboo flute (bashi), drums (dhol), a single stringed instrument named ektara, a four-stringed instrument called dotara, and a pair of metal bawls used for rhythm effect called mandira, are important in the culture of Bangladesh. Currently,musical instruments of western origin like guitars, drums, and the saxophone are used, sometimes along with traditional instruments (Muajj).
As the most important religious festival for the majority of Muslims, the celebration of Eid ul-Fitr has become a part of the culture of Bangladesh. The government of Bangladesh declares the holiday for three days on Eid-ul Fitr. But practically, all schools, colleges and offices remain closed for a week. This is the happiest time of the year for most of the people in Bangladesh. All outgoing public transport from the major cities have become highly crowded and in many cases the fares tend to rise in spite of government restrictions. On Eid day, the Eid prayers are held all over the country, in open areas like fields, Eidgahs or inside mosques. After the Eid prayers, people return home, visit each other's home and eat sweet dishes called Shirini, Sheer Khurma and other delicacies like biryani, korma, haleem, kebab etc. Throughout the day people embrace each other and exchange greetings. It is also customary for junior members of the society to touch the feet of the seniors, and seniors returning blessings (sometimes with a small sum of money as a gift). Money and food is donated to the poor. In the rural areas, the Eid festival is observed with great fanfare. Quiet remote villages become crowded. In some areas Eid fairs are arranged. Different types of games including boat racing, kabaddi, and other traditional Bangladeshi games, as well as modern games like cricket and football are played on this occasion. In urban areas, people play music, visit each other's houses, arrange picnics and eat special food. The homes, streets, markets and parks are illuminated with lighting decorations in the evening. Watching movies and television programs has also become an integral part of the Eid celebration in urban areas. All local TV channels air special program for several days for this occasion
The second most important religious festival. The celebration of Eid ul-Adha is similar to Eid ul-Fitr in many ways. The only big difference is the Qurbani or sacrifice of domestic animals on Eid ul-Adha. Numerous temporary marketplaces of different sizes called hat operate in the big cities for sale of Qurbani animals (usually cows, goats and sheep). In the morning on the Eid day, immediately after the prayer, affluent people thank God for the animal, and then sacrifice it. Less affluent people also take part in the festivity by visiting houses of the affluent who are taking part in qurbani. After the qurbani, a large portion of the meat is given to the poor people. Although the religious doctrine allows the sacrifice anytime over a period of three days starting from the Eid day, most people prefer to perform the ritual on the first day of Eid. However, the public holiday spans over three to four days. Many people from the big cities go to their ancestral houses and homes in the villages to share the joy of the festival with friends and relatives.
Pôhela Boishakh is the first day of the Bengali calendar. It is usually celebrated on 14 April. Pohela Boishakh marks the start day of the crop season. Usually on Pôhela Boishakh, the home is thoroughly scrubbed and cleaned; people bathe early in the morning and dress in fine clothes. They spend much of the day visiting relatives, friends, and neighbours and going to the fair. Fairs are arranged in many parts of the country where various agricultural products, traditional handicrafts, toys, cosmetics, as well as various kinds of food and sweets are sold. The fairs also provide entertainment, with singers, dancers and traditional plays and songs. Horse races, bull races, bullfights, cockfights, flying pigeons, and boat racing were once popular. All gatherings and fairs consist a wide spread of Bengali food and sweets. The most colourful New Year's Day festival takes place in Dhaka
