One of the most important roles of modern school is giving students the possibility to engage in extracurricular activities. However, many schools neglect extracurricular activities, even though they can be extremely beneficial to students especially if they stimulate creativity. Besides being simulative for sensible organization and useful spending of spare time, they can also prevent the occurrences of students behaving unacceptably usually when spending spare time is not organized. The results of most researches show that extracurricular activity in connection with music plays especially important role among other extracurricular activities. Today, it is almost impossible to think of a school performance or manifestation without singing, playing instruments or dancing to music whether it was traditional folk music or some modern musical expression. The importance of music is manifested in facts that students see musical activities as possibilities to have fun, to socialize and to learn. There is an atmosphere of team work, mutual respect, appreciation and encouragement. One of the most important musical aspects is singing which was, through centuries, the only or at least major curricular activity. There are some indications that the first music, due to the way of life of the first people, was vocal because the pitch and therefore tone was changed to transfer certain meanings. The importance of singing was also pointed out by German composer G. F. Telemann who considered singing the basis for musical teaching. My theses are closely related to extracurricular musical activities with a special emphasis on singing and conducting children choir in lower grades involving pupils from first to fourth grade of primary school.
