One of the only things that the cavalry had in common with the infantry was 'Taps' All the other calls Last Post etc. were quite different. Cavalry Calls were made on a trumpet as opposed to a bugle which was simply longer and larger and in a different key. As far as I know there was a sort of mouth music which one learnt to remember the calls. Playing the calls is called 'Sounding' by the way and the mouth music thing imitated the way the call was tongued. e.g. da dum digidigi dum da dum da digidigi dum. Each of the calls also had words some of which were quite rude and others quaint. Mess Call for instance was "I wentto the cookhouse and what did I see fuckall for supper and fuckall for tea. Last Post started "If he wants to die let him die"
