As part of the British brass band tradition of contesting, bands are split into five main brass band sections in the United Kingdom. These are the Championship, First, Second, Third, and Fourth sections. In some contests, a Youth section is also used, but this is not graded. The adjudicator for qualifying contests sits enclosed and unable to see the bands as they play, and then judges them on various points, one of which is interpretation.

In Britain, a brass band is a musical ensemble comprising a standardized range of brass and percussion instruments. The modern form of the brass band in the United Kingdom dates back to the 19th century, with a vibrant tradition of competition based around communities and local industry, with colliery bands being particularly notable. The Stalybridge Old Band was formed in 1809 and was perhaps the first civilian brass band in the world.
