Music-AR: Augmented Reality in Teaching the Concept of Sound Loudness to Children in Pre-School

Since the mass media and the lack of mandatory music education in Brazilian schools, there was a loss of perception of sound / music of Brazilian children. This fact, coupled with the lack of software for teaching and sound perception, enhances the problem. This paper presents the Music-AR, an augmented reality software for teaching sound properties such as pitch, loudness and volume. This application allows children manipulate virtual objects that are associated with sound, allowing them to learn sound bass and treble. The results of a usability test are presented.
