In elemental music and dance education and other music education subjects, in addition to individual musical and movement-related possibilities, communicative and relationship-oriented skills play a key role in the design of artistic-pedagogical teaching-learning processes. A precise assessment of the ability and quality of relationship and the subsequent reflection on the teaching situation, which is made possible by the "AQR-P Tool" observation and assessment procedure presented here, can support an adequate adaptation of the teacher's actions to the needs of the learners. By knowing the currently existing relationship mode and the "pedagogical relationship quality" to be adapted to it, the teacher can design tasks and activities in such a way that the learners can make optimal use of these activities. Volume 1 explains the theoretical foundations upon which the AQR-P Tool was developed and adapted and presents the observation procedure in its entirety so that it can be used directly in practice. In addition, the application possibilities and further development variants are shown.
