The "Last Post" </Td> </Tr> <P> The "Last Post" is either a B ♭ bugle call within British infantry regiments or an E ♭ cavalry trumpet call in British cavalry and Royal Regiment of Artillery (Royal Horse Artillery and Royal Artillery) used at Commonwealth military funerals and ceremonies commemorating those who have been killed in war . Its duration varies typically from a little over one minute to nearly three minutes . For ceremonial use, the Last Post is often followed by "The Rouse", or less usually the longer "Reveille". </P> <P> The two regimental traditions have separate music for the call (see Trumpet & Bugle Calls for the British Army 1966). While the B ♭ infantry bugle version is better known, the E ♭ cavalry trumpet version is used by the state trumpeters of the Household Cavalry . </P>
