Guido of Arezzo
In the 12th century, a development in teaching and learning music in a more efficient manner had arisen. Guido of Arezzo's alleged development of the Guidonian hand, more than a hundred years after his death, allowed for musicians to label a specific joint or fingertip with the gamut (also referred to as the hexachord in the modern era). Using specific joints of the hand and fingertips transformed the way one would learn and memorize solmization syllables. Not only did the Guidonian hand become a standard use in preparing music in the 12th century, its popularity grew more widespread well into the 17th and 18th century. The knowledge and use of the Guidonian hand would allow a musician to simply transpose, identify intervals, and aid in use of notation and the creation of new music. Musicians were able to sing and memorize longer sections of music and counterpoint during performances and the amount of time spent diminished dramatically.
Athletics at the 1912 Summer Olympics – Men's two handed discus throw
The men's two handed discus throw was a track and field athletics event held as part of the Athletics at the 1912 Summer Olympics programme. It was the only appearance of the event at the Olympics, along with the other two handed throws. The format of the event was such that each thrower threw the discus three times with his right hand and three times with his left hand. The best distance with each hand was summed to give a total. The three finalists received three more throws with each hand. The competition was held on Saturday, July 13, 1912. Twenty discus throwers from six nations competed.
