Musical instrument classification systems are diverse, often developed for specific cultural needs, though a widely adopted Western model exists. This prevalent Western system categorizes instruments into strings (subdivided into bowed and plucked), winds (woodwind and brass), percussion, and electronic instruments. Its historical roots trace back to ancient Greek thinkers like Nicomachus and Porphyry, evolving from earlier two-class systems proposed by 2nd-century grammarian Julius Pollux that initially grouped percussion (including strings) and winds. Figures like Martin Agricola further refined the string categories, while later distinctions were made between woodwinds and brass based on how air is set in motion. However, this scheme often struggles with instruments like the serpent, which functionally blurs woodwind and brass, or keyboard instruments such as the piano, which feature struck strings and defy easy categorization. Consequently, keyboard instruments are frequently treated as a separate category, demonstrating that this classical system often prioritizes playing technique over the fundamental method of sound production.
