Usually in physics mathematics we study and discuss invariance, symmetries of physical systems, under some changes the physical properties of a system do not change. Also may we discuss invariance, symmetries in literature, under some changes (changing the places of words) is it possible to observe the invariance of the meaning. For example let us study the sentence "To study music, we must learn the rules.

To create music, we must break them." by Nadia Boulanger. There are four action words study, learn, create, break; by changing their places we may write 24 sentences

I believe that music and mathematics have different genesis. I understand mathematics as an invention, a way of understanding reality that is created by men, therefore imperfect, imprecise and incomplete. Unlike music. Music is life itself, but how we organize it depends on human subjectivity. Music and poetry and memory. It is the wind itself acting on the waves. They exist without the need for humans. understanding music beyond the concepts we humans create
