The Band of the Welsh Guards was formed in the same year as the Regiment (1915), and consisted of forty four musicians and a Warrant Officer - Andrew Harris, their Bandmaster. Their first set of instruments were presented by the City of Cardiff, which enabled the Band to carry out the first Kings Guard Mounting on St. David's Day 1916. On the same day it gave its first concert on the stage of the London Opera House and the evening was such a success that the Band's reputation for its high standard was immediately established.

Since its early beginnings, the Band has toured extensively and brought the pomp and pageantry of British life to many far-flung corners of the world. In recent years it has visited Belgium, Egypt, Spain the USA and Canada. Within its ranks the musicians come from a variety of backgrounds such as colleges, academies, other military bands and orchestras. Permanently based in London, its members enjoy a varied and challenging musical career. They can regularly be seen at the ceremony of Changing The Guard at Buckingham Palace and many other State and ceremonial occasions. The Band also performs frequently with many of the world's finest orchestras in some of the most spectacular extravaganzas staged in Great Britain.

Links with the Battalion's traditional recruiting areas in Wales are also maintained by regular public appearances there, often with many of the fine male voice choirs for which the Principality is renowned. Involvement with children and young people in instrumental clinics and music workshops is always a priority, and close ties with various schools and colleges have successfully developed through these avenues. Concerts are also given regularly for charities such as The Army Benevolent Fund, The Royal British Legion and The Soldier's Sailors and Air Force's Association.

Through its unique blend of stirring music and colourful ceremony, The Band of the Welsh Guards continues to appeal to both young and old by following fine traditions and values envied throughout the world.
