Egocentrism means giving value to own self-interest more and less or no regards to other's interest. One example of Egocentrism I encounter in my life is that people thinks that their own point of view is right and ignorant of other's point of view and more possibilities of solution of the problem other than own. Another word - Sociocentrism means giving value to own group's interest and assuming our group is the right one. One example of this I observed in life is the school/university you came from that such belief that we are better than them because we enrolled or came from this school. These things create a barrier in critical thinking because you exclude some possibilities and opportunities that may others possess. Some techniques that can overcome the barrier are open communication and socializing with other peer groups. These techniques can lead you to open yourself to the society and to other people and learn new knowledge with them.
Medieval music consists of songs and pieces from an era of Western music, including liturgical music (also known as sacred) used for the church, and secular music, non-religious music. Medieval music includes solely vocal music, such as Gregorian chant and choral music (music for a group of singers), solely instrumental music, and music that uses both voices and instruments (typically with the instruments accompanying the voices). Gregorian chant was sung by monks during Catholic Mass. The Mass is a reenactment of Christ's Last Supper, intended to provide a spiritual connection between man and God. Part of this connection was established through music.[1] This era begins with the fall of the Western Roman Empire in the fifth century and ends sometime in the early fifteenth century. Establishing the end of the medieval era and the beginning of the Renaissance music era is difficult, since the trends started in different regions. The usage in this article is the one usually adopted by musicologists.
During the Medieval period the foundation was laid for the notational and theoretical practices that would shape Western music into the norms that developed during the common-practice era. The most obvious of these is the development of a comprehensive music notational system which enabled composers to write out their songs and pieces on parchment or paper. Prior to the development of musical notation, songs and pieces had to be learned "by ear", from one person who knew a song to another person. This greatly limited the geographic spread of songs or pieces. The development of music notation made it easier to disseminate songs and musical pieces to a larger geographic area. However the theoretical advances, particularly in regard to rhythm—the timing of notes—and polyphony—using multiple, interweaving melodies at the same time—are equally important to the development of Western music.
