In every part of the world, there is a particular set of factors that can be attributed to one country or culture. Though steel pan music is now heard worldwide, it is known as a sound that is unique to the Caribbean. After all, the birth of this instrument, also called a steel drum, happened in the Caribbean's most southern island of Trinidad.

The 'pan' - as it is affectionately referred to on the island - was created in the 1930s, after a long period of experimenting with various metal objects to use as percussion instruments. This happened as a result of the African hand drums, which had been brought to the region during the slavery period - being banned by British rulers over half a century before. This had been an attempt to suppress festivities associated with Carnival.

The drum was originally created using huge 55-gallon oil drums. These were pounded and polished to created the instrument as we know it today. This method is still one of the most widely used methods to make the steel pan, thought sheet metal as a starting point is also used. This is the only instrument to be invented during the 20th century, putting it in the history books forever.

This is an instrument that can be played by itself or in groups to create a steel band. The music is celebrated particularly at Carnival time, when special competitions and events are held to determine the greatest band of them all. Spectators are able to join in the vibe and feel the energy of the sound live at these events.

Though the instrument traditionally celebrates local musical genres of calypso and soca in Trinidad & Tobago, it can actually be used in any genre of music. Sounds of the pan can be heard in jazz, pop, reggae and also Latin. It has even been used in rap and hip-hop, for example, in 50 Cent's chart-topping hit "P. I. M. P.". The global reach of the instrument has led to debates over its origins.

There are various pan types for different pitches, or tones. Those pans found in the frontline section play the melodies and counter melodies because they have the highest pitch. These are namely the tenor and double-tenor pans. In the mid-range, the quadrophonic, cello and guitar pans play harmonies and also counter melodies.

Those pans with the lowest pitch are found in the background section of the band. They provide the bass line which the entire band will follow for any particular song. The dudup and the 4-note bass pan are found here. Other percussion instruments are often used in a steel band, and they are located in a section of the band called the engine room.

Certain figures are prominent when discussing the history and development of this unique instrument. Anthony Williams is a big name in the discussion; he was the first to create the pan using oil drums. He is also the creator of the 'spider web' pan, which, due to its layout, has a much higher quality of sound. Winston Simon created the eight-pitch melody pan, while Ellie Mannette is credited with wrapping pan playing sticks with rubber, which greatly refined the sound.
