One of the longest-lived string instruments, which has changed over the course of history and reached many different stages of development, which has the capabilities of a wide spectrum of sound, dynamics and various aleatoric possibilities, is the double bass. As society evolved, so did the structure of the double bass. The roles of the double bass in the musical world changed and developed, the way of working and the position of the double bass, which, as an instrument whose role at the very beginning was rhythmic and chordal accompaniment, reached the elementary and indispensable instrument of the symphony orchestra. However, in order to be able to play the double bass correctly and skillfully, an effective method is needed by which professors should approach their students so that they master the techniques essential for playing the double bass in a proper and efficient manner. A methodical approach to the double bass requires great persistence, dedication and commitment to the instrument. With this work, I want to point out the approach of teaching the double bass to students of preparatory classes and high school students. I will provide a summary of how to place the instrument over all the technical difficulties that are considered mandatory for playing the double bass and I will point out the educational, functional and educational methods that should be applied when teaching so that the teaching could result in a favorable outcome. The first part of my thesis will focus on the main types of approaches of teachers and students of preparatory classes, and in the second part of my thesis I will focus on the approach of teachers and students of secondary schools. The work will be focused on technical problems, for example the position of instruments and bows, the practice routine and the preservation of the musician's working ability.
