One of the leading groups of genres in which the interaction of vocal and instrumental principles is possible is chamber-vocal works, where one of the participants in the creative dialogue is the piano. The development of chamber and vocal works demonstrated the vitality and leading importance of the genre for musical culture. In the context of the history of music, we can distinguish various forms of interaction between voice and piano. The field of chamber and vocal creativity has repeatedly attracted the attention of scientists. However, due to the fact that it has been developing since the XIX century, the period of its existence to this day often remains little studied. Accordingly, the question of the formation of chamber and vocal piano works is a problem that opens a significant field for studying aspects of the formation of this group of genres. The combination of vocal and instrumental principles has an extremely long history. For a long period of time, vocal was given priority over the instruments that accompanied it. Regarding the question of the unity of vocal and instrumental principles in one work, it was present as early as the times of ancient cultures. As a rule, the instrumental accompaniment played a secondary function in relation to the voice, providing support, tuning, shading the voice or simply filling in the pauses necessary for the rest of the vocalist. With the advent of the Renaissance and the development of various secular vocal genres, there are various works, both purely vocal (polyphonic) and vocal-instrumental. Among the polyphonic genres can be distinguished barcarole, villanelli, frottoli, madrigals, canzones. They are dominated by a polyphonic composition, which provides for «equality» of all voices. Chamber-vocal piano works occupy an important place in the singer's activity. The process of forming a duet of voice and piano had a long prehistory. The stage of the final formation of this genre falls on the XVIII century, and this is facilitated by a number of factors – the arrival of the piano to replace keyboard instruments, its predecessors, and the worldview of the Classicist era. A very important factor is the formation of dialogue between the instrument and the voice, which changes the priority of the vocals. During this period, a kind of summary of the achievements of previous centuries is carried out and conditions are laid for the following directions, in which chamber vocal-instrumental piano works will acquire a fundamentally different quality level.
