A march is a musical composition with a strong regular rhythm which in origin was expressly written for lockstep marching of soldiers. As a musical genre, it is a type of martial music, most frequently performed by a military band during parades.

March music pieces vary widely in mood, ranging from the emotional funeral march in Wagner's Götterdämmerung to the brisk Romantic marches of John Philip Sousa and the militaristic hymns of the late 19th century. Examples of the varied use of the march can be found in Beethoven's Eroica Symphony, in the Marches Militaires of Franz Schubert, in the Marche funèbre in Chopin's Sonata in B flat minor, the "Jäger March" in the Op. 91a by Jean Sibelius, and in the Dead March in Handel's Saul.

Buckingham Gate is a street in Westminster, London, England, near Buckingham Palace. It contains a number of embassies, hotels and businesses, and since September 2025, includes Liberal Democrat Headquarters, housing one of Parliament's three largest political parties, which is based at 66 Buckingham Gate.

The roadways of Buckingham Gate were first constructed in 1680, but were known by different names. Prior to 1820, the name of Buckingham Gate referred to an actual gate with a gatehouse and a gate guard, controlling access to the Queen's Palace and the Wellington Barracks, siting on the border of Queens Garden and St. James Park. The eastern portion of the modern Buckingham Gate was once known as Stafford Row and the Queens' Wards. The western portion was known as James Street. As well, prior to 1828, the eastern portion was reserved exclusively for use by members of the royal family.
