The article is devoted to the study of the essence of the phenomenon “performing will” as an important professional quality of future specialists in the field of art education. The purpose of the article is to substantiate the essence, content and component structure of the performing will generated by future Music teachers, in the context of choirmaster (choral) training in particular. These methods are used in the article: analysis, synthesis and generalization (in order to substantiate the key provisions of the study); the method of shifting from the abstract entities to the concrete ones (in order to study the essence of the complex concept "performing will of a Music teacher in the context of choral training"); the methods of modelling and systematisation (in order to study the structural components of the phenomenon under study). Based on the study, it was determined that the choirmaster training aimed at the future Music teachers involves mastering the competence in specific activities with pupils’ non-amateur and amateur choirs, as well as mastering the forms and methods of organising pupils’ group choral performance. The performing will of the future Music teacher in the context of choirmaster training is considered as individual basic personal and professional properties which provide mental and emotional influence of the conductor on the members of the choir to unite them on the basis of emotional and spiritual resonance. The will of the conductor-choirmaster acts as a mechanism of energy impact on each member of the team in order to achieve the necessary, highly artistic and convincing level of implementation of the performance conception as an intonation-auditory and emotional image of the musical work envisioned by the conductor. Based on the definition of the content-oriented and attributive characteristics of the performing executive will, the component structure of the studied phenomenon is substantiated, it consists of four interconnected components: motivational-incentive, intonation- and image-centred, manual-expressive and reflexive-corrective
