Experimental theatre in the Arab world: Experimental theatre in the Arab world emerged in the post-colonial era as a fusion of Western theatrical traditions with local performance cultures such as music and dance.  It is characterized by hybridity as it transposes Arabic traditional performances that were usually seen in public squares and marketplaces to theatre buildings.  Experimental theatre in the Arab world has historically taken forms of Forum theatre by using audience participation as a way to smooth conflicts and resolve social tension.  The audience is then transformed from a commonly passive into a proactive and involved one.  It has been seen as a form of theatre of resistance and cultural activism as it deals with contemporary sensitive issues of the region such as the Israeli–Palestinian conflict, the Arab Spring, the role of women in Arabic society and religion.  Such issues are often dealt with using humour.  Throughout the years, experimental theatre in the Arab world has gradually converted into a synonymous of non-mainstream and underground art movements in which artists are always evolving and breaking down conventional markers between actors and spectators.  The script combines the appropriation and dis-appropriation of Western models and is usually organic, more improvisational and self-reflexive.  In the late 2000s, improvisational theatre which takes forms of stand up comedy shows has also emerged around the Arab world.

Silambu: Silambu (Tamil: சிலம்பு ) is a traditional anklet worn mostly by South Indians.  This ornament is referred to in the famous Tamil silapapthigaram, where the story begins and ends with a silmabu.  In olden days, both men and women wore a variety of silambu.  This can be discovered in most of the Tamil texts.  A silambu, worn by a woman, is a hollow circular tube, made of gold, with precious stones or pearls to fill the space, which in turn produce a characteristic sound while walking.  Silambus are worn by traditional dancers during performances.  This produces a rhythmic, jingling sound in tune with the steps of the dancers.

Filipino American music: Filipino Americans have a long history of music in the United States.  The Philippines have musical context and varied influences due to indigenous traditions and early colonial influences of Spanish and American occupation.  During occupation by the United States, many Filipinos were recruited for manual labor along the West Coast.  These early laborers commonly would perform Spanish-influenced rondallas as well as choral groups.  With many Filipinos living in the United States beginning around 1900s, Filipinos have contributed towards early Americana staples such as blues and jazz, and continue to influence more modern contemporary genres such as hip hop and rock.  American music has also been influential in the Philippines for artists and vice-versa.  Though contributing to the evolution of American music, large number of Filipino Americans have a strong identity with culture of the Philippines by participating or organizing traditional dances and musical performances, largely in the form of PCNs on university campuses.  Traditional dances and musical performances commonly practiced in the US are rondallas, choral groups, and gong chime ensembles.  College campuses often organize performances on campuses, but can also have characteristics unique to America, as many Filipino Americans want to share their experiences of living in America and perform a more neo traditional variation of traditional performances.

Ghungroo: A Ghungroo (Hindi: घुँघरू , Urdu: ‎ ), also known as Ghunghroo or Ghunghru or Ghungur (Bengali) is one of many small metallic bells strung together to form Ghungroos, a musical anklet tied to the feet of classical Indian dancers.  The sounds produced by Ghungroos vary greatly in pitch depending on their metallic composition and size.  Ghungroos serve to accentuate the rhythmic aspects of the dance and allow complex footwork to be heard by the audience.  They are worn immediately above the ankle, resting on the lateral malleolus and medial malleolus.  A string of ghungroos can range from 50 to greater than 200 bells knotted together.  A novice child dancer may start with 50 and slowly add more as he or she grows older and advances in his or her technical ability.  Ghungroos or Salangais are worn in traditional performances of the classical Indian dance forms: Bharatnatyam, Kathak, Kuchipudi, Lavani and Odissi etc.

Irish stepdance: Irish stepdance is a style of performance dance with its roots in traditional Irish dance.  It is generally characterized by a stiff upper body and quick and precise movements of the feet.  It can be performed solo or in groups.  Aside from public dance performances, there are also stepdance competitions all over the world.  These competitions are often called Feiseanna (singular Feis).  In Irish dance culture, a Feis is a traditional Gaelic arts and culture festival.  Costumes are considered important for stage presence in competition and performance Irish stepdance.  In many cases, costumes are sold at high prices and can even be custom made.  Males and females can both perform Irish stepdance but for the most part in today's society, the dance remains predominantly female.  This means that the costumes are mainly dresses.  Each dress is different, with varying colors and patterns, designed to attract the judge's eye in competitions and the audience's eye in performance.  General appearance besides the costume is also equally important.  Dancers would typically curl their hair before each competition.  Many dancers invest in curled wigs that match their hair color.  Poodle Socks are worn with the dresses and shoes.  These are white socks that stretch to mid calf with distinctive ribbing.

Gamucha: Gamucha (also "gamocha" (ga=body, mocha=wipe), "gamchcha", "gamcha") is a thin, coarse, traditional cotton towel found in India, Bangladesh as well as various parts of South and Southeast Asia and is used to dry the body after bathing or wiping sweat.  Gamucha is the local term for a sweat towel.  It is often just worn on one side of the shoulder.  However its appearance varies from region to region.  Gamucha has been traditionally worn as scarf by male folks of Orissa which was mentioned in Oriya Mahabharata by Sarala Dasa.  Male villagers wear it as dhoti.  Children of tribal communities in Orissa wear gamucha until their adolescence after which they wear dhoti.  Weavers of traditional "tantubaya" or "jugi"community migrated from Bangladesh to Tripura and weavers of Orissa produce good quality gamucha.  Gamucha is most commonly found with check and striped patterns of red, orange or green.  Plain white gamchhas with coloured (embroidered or printed) borders from Orissa and Assam (for traditional Assamese Gamucha, see Gamosa) are local handicrafts, and may be worn around the neck with traditional Indian attire.  In western areas, gamucha is primarily made in red colour and are plain like cloth.  In southern India, gamucha is more coarse and are available in various dyes.  Even homemade lightweight fur towels are also popularly termed as gamchhas.  Gamucha are worn by the South Asian people, especially in the Indian states of Andhra Pradesh, Bihar, West Bengal, Jharkhand and the Purvanchal region, because they are not as thick as Western-style towels and better suited to the country's tropical, humid climate.  In Afghanistan they are also used and are commonly referred to as dismaal.  They may also be found in Central Asian, Middle Eastern and Turkish hamams as a traditional male loin cloth and towel worn during bathing and massage.
