The lyrics use a mix of everyday vocabulary and poetic, metaphorical language (e.g., 'Wogen der Nacht', 'Sinfonie der Nacht', 'Glut und Asche'), which goes beyond basic A-level comprehension but does not reach the complexity of advanced C-level texts. The grammatical structures are mostly straightforward, with repetitive chorus sections that aid understanding, while some figurative expressions and imagery require a moderate level of language proficiency to fully interpret.
