Singing individually is both a necessary activity within the music class and an essential part of the cultural activity of improvising verses through singing. In this article we show how the introduction of this activity in the educational system of Catalonia has made it possible to obtain positive results with regard to participation in singing, especially solo singing. The analysis of the data also shows how this type of singing activity has a positive effect on negative attitudes towards singing derived from western perceptions of who or who isn't competent to sing, depending on gender, age and social status.
