This paper focuses on how the compositional processes, the development of the guitar as an instrument, and its performance techniques specifically affected the foliatheme and the variations written for this instrument, considering that the foliatheme and the variations
have constantly evolved over four centuries. In this research, the foliais treated as the framework, the role of improvisation and variation in the evolution of a musical work in general and the historical, cumulative effects on the foliaare ontologically viewed within the model ‘living organism’.
Musical forms evolve during the course of history. When composers add new elements to their work in a given form, they cumulatively contribute to the evolution of that form. The main elements that help this evolution are melody, rhythm, harmony, style, structure, and the development of instrumental technique. In thisarticle, the influence of the evolution of instruments and performance technique on the composition of foliaswill be investigated.
