The artwork “A Criação do Dia” (The Creation of the Day) is a classical piece made for full orchestra composed by Lalalli Senna for the Orquestra Sinfônica Municipal de João Pessoa (OSMJP), a Symphony Orchestra located in the state of Paraíba, Brazil, and was first presented in the opening of the 3º Festival Internacional de Música Clássica de João Pessoa, in 2015. The original inspiration for this artwork lays in the traditional Brazilian regional rhythms such as the baião, essential part of the culture, history and landscape of Paraíba. Lalalli considers Paraíba a lifespring of composers and artists with high influence over her creations. The main theme of “Criação do Dia” depicts the Sun as the protagonist along to its eternal cycle of birth, death and resurrection. Therefore, it’s a cyclical artwork, which begins and ends under the same musical theme. The Sun is presented through its earthly feature — linked to the natural-telluric elements within a context of the Savannahs, and related to the “rhythms of the earth”, represented in quaternary rhythms (the four seasons, the four elements), and also its cosmic/celestial dimension, represented in ternary rhythms. This piece shows an integration of these two numerical representations, 3 and 4, the celestial and the earthly, and the life that results from their union. The author dedicates this artwork to the state of Paraíba, to the People of Paraíba, and to the OSMJP. As expected, “Criação do Dia” was warmly welcomed into audiences and has been continuously executed by the João Pessoa Symphony Orchestra, being considered one of the most representative compositions in their repertoire.
