Today's children face the use of mobile technology much earlier than previous generations. School should be the place where they can improve their knowledge and it should guide them to the useful side of technology. Technology is being slowly implemented into education but still not as the individual way of learning, but as the easier way of teaching. At the same time, many applications, web tools and other interesting ways of learning and teaching come out. However, they are still not recognized in teaching as a possible solution for learning/revising content or motivating students for independent work. Previous research has shown that students and teachers are both interested in using smartphones in classrooms. Despite of that, teachers still hesitate. They are afraid of failure attempts because there is no specified way of using them. Music classes in primary education, which use an open model, are suitable for implementing mobile technology. There are many music applications that can stimulate student’s interest in music content. However, almost none of these applications are adjusted according to students’ achievements expected in primary education. The main reason is insufficient recognition of multimedia and mobile technologies as a possible way of learning. This would not mean completely avoiding today's learning and teaching techniques, but finding the potential of technology as a way of more successful learning. In this paper there are some web tools and music applications that can be used in the Music class and possible suggestions on how to use them. Furthermore, in the second part of the paper, there is a research part that provides students’ and teachers’ feedback in using smartphones while teaching Music.
