Obscure Musical Forms

I'm a collector of obscure and unusual musical forms such as the loure, the haka and, most recently, the chamade. 

• the loure, sometimes louré is described in Wikipedia: "The loure, also known as the gigue lourée or gigue lente (slow gigue), is a French Baroque dance, probably originating in Normandy and named after the sound of the instrument of the same name (a type of musette). It is of slow or moderate tempo, sometimes in simple triple meter but more often in compound duple meter. The weight is on the first beat, a characteristic emphasised by the preceding anacrusis, which begins the traditional loure. Another feature is the lilting dotted rhythm." The most famous example I know is from the E major violin partita also known as the Lute Suite No. 4.
• "Haka are a variety of ceremonial dances in Māori culture. Haka are often performed by a group, with vigorous movements and stamping of the feet with rhythmically shouted accompaniment. Haka have been traditionally performed—by both men and women—for a variety of social functions within Māori culture. They are performed to welcome distinguished guests, or to acknowledge great achievements, occasions, or funerals." [from Wikipedia]
• "In war, a chamade was a certain beat of a drum, or sound of a trumpet, which was addressed to the enemy as a kind of signal, to inform them of some proposition to be made to the commander; either to capitulate, to have leave to bury their dead, make a truce, etc. Gilles Ménage derives the word from the Italian chiamate, from Latin clamare, to call." [from Wikipedia] There is an even more interesting article about the organ stop en chamade.

Some examples: first, the Loure from the 4th Lute Suite:

Next a famous haka by the New Zealand All Blacks rugby team:

(I composed a haka for choir, but that's the only one I know of!) Finally, an organ performance using the en chamade stop:

It might be interesting to write a piece that references the military context. Here is a little clip, in French, describing how the term has evolved into modern speech where it means to be overcome by romantic emotion.
