What defines 'classical music'?

The concept of 'classical music' is defined by its broad tradition that spans multiple historical periods, particularly from the roughly 11th century through the present. This encompasses various styles and movements, including Medieval, Renaissance, Baroque, Classical, Romantic, and Contemporary music.

Each of these periods has distinctive characteristics, yet they collectively contribute to the overarching narrative of classical music's development. This genre is recognized not just for its aesthetic qualities, but also for its complex structures, intricate harmonies, and rich history rooted in Western art music tradition. Therefore, the definition effectively captures the diverse and evolving nature of classical music over time.

The other options suggest narrower interpretations that don’t align with the established understanding of classical music. For example, the idea of a modern genre with contemporary influences, or music primarily featuring electronic instruments, does not resonate with the historical context and depth inherent in classical music. Similarly, music designed specifically for mass marketing is typically associated with popular music rather than the serious artistic endeavors that classical music represents.
