The Guards, after standing at attention, change arms. Under the command of the Senior Drum Major, the Massed Bands march and countermarch on Horse Guards Parade in slow and quick time. The slow march music is traditionally the Waltz from "Les Huguenots". During the quick march, a lone drummer from the Corps of Drums breaks away from the massed bands, marching to two paces to the right of No. 1 Guard to take his post while the band marches on, stopping just near the colour party.
