when should the last post be played at a funeral
Last Post 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.[1] For ceremonial use, the Last Post is often followed by "The Rouse", or less usually the longer "Reveille".[2][3]
Three-volley salute The three-volley salute is a ceremonial act performed at military funerals and sometimes also police funerals. The custom originates from the European dynastic wars, where the fighting ceased so the dead and wounded could be removed. Then, three shots were fired into the air to signal that the battle could resume.[1]
