These poems are treating various themes, but in general, they all can be classified as lyrical poetry.
Reflections about life and the human condition, love, passion, joy, emotional woes, deception and disappointment are the most important subjects treated.
Other poems express love for nature, philosophical ideas and the unstoppable passing of time, and thus, life.
As to form, most poems have rimes, and some are classical in form, but free verse and experimentation with sounds also play a part, be it to a lesser extent.
