Information: - The Count of Champagne was the ruler of the region of Champagne from 950 to 1316. Champagne evolved from the county of Troyes in the late eleventh century and Hugh I was the first to officially use the title "Count of Champagne". - Theobald I (, often referred to as Thibaut de Navarre and Thibaut de Champagne) (30 May 1201 8 July 1253), also called the Troubadour and the Posthumous, was Count of Champagne (as Theobald IV) from birth and King of Navarre from 1234. He initiated the Barons' Crusade, was famous as a trouvere, and was the first Frenchman to rule Navarre. - A semitone, also called a half step or a half tone, is the smallest musical interval commonly used in Western tonal music, and it is considered the most dissonant when sounded harmonically. It is defined as the interval between two adjacent notes in a 12-tone scale. For example, C is adjacent to C; the interval between them is a semitone. - Old Occitan (Modern Occitan: "occitan ancian"), also called Old Provencal, was the earliest form of the Occitano-Romance languages, as attested in writings dating from the eighth through the fourteenth centuries. Old Occitan generally includes Early and Old Occitan. Middle Occitan is sometimes included in Old Occitan, sometimes in Modern Occitan. As the term "occitanus" appeared around the year 1300, Old Occitan is referred to as "Romance" (Occitan: "romans") or "Provencal" (Occitan: "proensals") in medieval texts. - Gace Brule ("c." 1160 "after" 1213), French trouvere, was a native of Champagne. - Chretien de Troyes ("Christian") was a late-12th-century French poet and trouvere known for his work on Arthurian subjects, and for originating the character Lancelot. This work represents some of the best-regarded of medieval literature. His use of structure, particularly in "Yvain, the Knight of the Lion", has been seen as a step towards the modern novel. Little is known of his life, but he seems to have been from Troyes, or at least intimately connected with it, and between 1160 and 1172 he served at the court of his patroness Marie of France, Countess of Champagne, daughter of Eleanor of Aquitaine, perhaps as herald-at-arms (as Gaston Paris speculated). - The High Middle Ages or High Medieval Period was the period of European history around the 11th, 12th, and 13th centuries (c. 10011300). The High Middle Ages were preceded by the Early Middle Ages and followed by the Late Middle Ages, which by convention end around 1500. - In music theory, a leading-note (also subsemitone, and called the leading-"tone" in the US) is a note or pitch which resolves or "leads" to a note one semitone higher or lower, being a lower and upper leading-tone, respectively. - Trouvere, sometimes spelled trouveur , is the Northern French (langue d'oil) form of the langue d'oc (Occitan) word "trobador". It refers to poet-composers who were roughly contemporary with and influenced by the troubadours (composers and performers of Old Occitan lyric poetry during the High Middle Ages) but who composed their works in the northern dialects of France. The first known "trouvere" was Chretien de Troyes ("fl". 1160s-1180s) (Butterfield, 1997) and the "trouveres" continued to flourish until about 1300. Some 2130 "trouvere" poems have survived; of these, at least two-thirds have melodies. - A troubadour was a composer and performer of Old Occitan lyric poetry during the High Middle Ages (11001350). Since the word "troubadour" is etymologically masculine, a female troubadour is usually called a trobairitz. - Jean II de Trie ( c. 1225 -- 1298 1304 ) was the first of his name ( John I ) and second of his house to be Count of Dammartin . He succeeded his father , Mathieu , in Dammartin and as lord of Trie and Mouchy , on the latter 's death in 1272 . He is the same person as the trouvere Jehan de Trie , to whom two surviving chansons courtoises have been attributed . One of these , Bone dame me prie de chanter , is also sometimes attributed to Theobald I of Navarre or Gace Brule . The other , Li lons consirs et la grans volentes , is undisputed . Both are isometric , decasyllabic , Dorian and set in bar form , and begin with the leading - tone ( the seventh degree ) . At one place in Bone dame there occurs the highly unusual octave leap downwards . According to the Chronique Tournaisienne , John died fighting for the king of France at the Battle of the Golden Spurs on 11 July 1302 . John had married first Ermengarde , then Yolande , daughter of John I of Dreux . The latter bore him two children : Renaud , who succeeded him prior to May 1304 , and Mahaut , who in 1298 married Henry de Vergy ( died 1333 ) . Some sources place his death at the Battle of Mons - en - Pevele on 18 August 1304 , but this is after his son Renaud had already become count in May . - In computer science, a radix tree (also radix trie or compact prefix tree) is a data structure that represents a space-optimized trie in which each node that is the only child is merged with its parent. The result is that the number of children of every internal node is at least the radix of the radix tree, where is a positive integer and a power of 2, having 1. Unlike in regular tries, edges can be labeled with sequences of elements as well as single elements. This makes radix trees much more efficient for small sets (especially if the strings are long) and for sets of strings that share long prefixes. - In computer science, a trie, also called digital tree and sometimes radix tree or prefix tree (as they can be searched by prefixes), is a kind of search treean ordered tree data structure that is used to store a dynamic set or associative array where the keys are usually strings. Unlike a binary search tree, no node in the tree stores the key associated with that node; instead, its position in the tree defines the key with which it is associated. All the descendants of a node have a common prefix of the string associated with that node, and the root is associated with the empty string. Values are not necessarily associated with every node. Rather, values tend only to be associated with leaves, and with some inner nodes that correspond to keys of interest. For the space-optimized presentation of prefix tree, see compact prefix tree.
