Beginning in the late Middle Ages, straight herald trumpets (known as the buisine) and later coiled valve-less natural trumpets, clarions and drums (usually snares and tenors) would sound fanfares to mark important holidays or ceremonial events.
Valved chromatic trumpets, originally developed in the 1930s, are the ones used today by most armed forces and a few police departments worldwide.
The prakhom band of the Bureau of the Royal Household of Thailand sports such old style trumpets, introduced into the country in the early years of the Bangkok (Rattanakosin) period replacing lost originals.
A similar but plain instrument, the nafiri, is used as part of the regalia of Malaysia because it is an integral part of the nobat or royal orchestra which performs in important royal events in the states of Kedah, Perak, Terrenganu and Selangor and when the Yang di-Pertuan Agong from those states is ceremonially installed.
Modern fanfare trumpets have an elongated bell extending far in front of the player, allowing a standard length of tubing from which a flag or banner may be hung; the instrument is mostly used for ceremonial events such as parades.
