Music Concord is a fun music quiz app which interacts with the user. Music is composed and performed for many purposes, ranging from aesthetic pleasure, religious or ceremonial purposes, or as an entertainment product for the marketplace. When music was only available through sheet music scores, such as during the Classical and Romantic eras, music lovers would buy the sheet music of their favourite pieces and songs so that they could perform them at home on the piano. With the advent of sound recording, records of popular songs, rather than sheet music became the dominant way that music lovers would enjoy their favourite songs.
