Problem: Please answer a question about the following article about Middle Ages:
Popes called for crusades to take place elsewhere besides the Holy Land: in Spain, southern France, and along the Baltic. The Spanish crusades became fused with the Reconquista of Spain from the Muslims. Although the Templars and Hospitallers took part in the Spanish crusades, similar Spanish military religious orders were founded, most of which had become part of the two main orders of Calatrava and Santiago by the beginning of the 12th century. Northern Europe also remained outside Christian influence until the 11th century or later, and became a crusading venue as part of the Northern Crusades of the 12th to 14th centuries. These crusades also spawned a military order, the Order of the Sword Brothers. Another order, the Teutonic Knights, although originally founded in the crusader states, focused much of its activity in the Baltic after 1225, and in 1309 moved its headquarters to Marienburg in Prussia.
Where was the Teutonic Order headquartered in 1309?
A: Marienburg
Problem: Please answer a question about the following article about Frederic Chopin:
In 1841, Leon Escudier wrote of a recital given by Chopin that year, "One may say that Chopin is the creator of a school of piano and a school of composition. In truth, nothing equals the lightness, the sweetness with which the composer preludes on the piano; moreover nothing may be compared to his works full of originality, distinction and grace." Chopin refused to conform to a standard method of playing and believed that there was no set technique for playing well. His style was based extensively on his use of very independent finger technique. In his Projet de methode he wrote: "Everything is a matter of knowing good fingering ... we need no less to use the rest of the hand, the wrist, the forearm and the upper arm." He further stated: "One needs only to study a certain position of the hand in relation to the keys to obtain with ease the most beautiful quality of sound, to know how to play short notes and long notes, and [to attain] unlimited dexterity." The consequences of this approach to technique in Chopin's music include the frequent use of the entire range of the keyboard, passages in double octaves and other chord groupings, swiftly repeated notes, the use of grace notes, and the use of contrasting rhythms (four against three, for example) between the hands.
What writing of Chopin talks about everything about piano playing has to do with proper fingering?
A: his Projet de methode
