This exposition represents a series of piano compositions of which the rhythmic structure is derived and developed from the language of Zarathustra's homonymous book of poems (The Gāthās), Gāthic or Old Avestan which belongs to the ancient Iranian language group that is a sub-group of Eastern families of the Indo-European languages. These pieces were formed by applying the poem's meter which is historically related to the Vedic tristubh-jagati family of meters. This project, in content, was inspired by the poems expounding on the divine essences of truth (Asha), the good-mind (Vohu Manah), and the spirit of righteousness.
