The massive interest and enthusiasm for musical art on a digital basis is high today. Electronic tools attract with their accessibility and multi-timbral colorfulness. The computerization of music education, modern educational standards in the new WorldSkills movement paradigm, the relevance of the development of media education and self-educational technologies to improve the professional self-development of a modern music teacher determine the problem of researching and substantiating modern forms of electronic-creative music making-arranging as a means of digital electronic space. Available information on the problem requires a systematization of arrangement knowledge and skills based on digital electronic space. This determined the purpose of the study, which is to create working conditions for the arrangement and design supporting electronic content in the form of digital electronic space for the self-development of relevant skills by a music teacher. An analysis of the concepts revealed the pedagogical tools for constructing the arranging process, determined the consideration of composition and electronic arranging skills as the main methods of sound intonation and re-intonation of the musical sense of music, and contributed to the presentation of the substantive side of the musician's universal competence. The computer-musical shell as a "digital electronic space" should possess all the features of a training system where books and articles on arrangement will be studied, individual practical implementation of musical tasks independently chosen by the user according to the level of complexity and time of execution, with the possibility of self-control (testing knowledge and skills). Only in this case a comfortable educational environment will arise when the student will be able to independently carry out macro navigation and form their own learning routes.

The article examines electronic arrangements as an art of intonating meanings, a universal means of developing musical culture of society, and a form of artistic activity of the future music teacher. The authors base themselves on analysis of conceptions of cultural-historical development in the choice of genre forms of electronic music-making, accentuate the logical, emotional and associative aspect of artistic creativity and highlight the stages of work on arrangements. The article discloses a teaching system presented in the form of a logical-semantic model, which includes the technology of comparative listening to music, a tutorial program complex “The Life of Wonderful Melodies,” an electronic musical toolkit and supportive musical examples of arrangements and samples of sound.
