In the last decade the author has launched a new theoretical project to renew the so-called classical semiotic approach and to rethink its epistemological basis. These theoretical and philosophical reflections have started from the hypothesis that semiotics cannot stay forever as Peirce, Saussure, Greimas, Lotman, Sebeok and others have established it. Semiotics is in flux and reflects new epistemic choices in the situation of sciences in the twenty-first century. The author presents some aspects of problem: e.g. contept 'moi' and 'soi' in music, change of Hegelian concepts 'an-sich sein' (being-in-itself) and 'für-sich-sein' (being-for-itself) into 'an-mich sein' (being-in-myself) and 'für-mich-sein' (being-for-myself). In the final part of this essay, he would present an analysis of the first movement of Beethove's Sonata in E flat major op. 7.
