What is hornbostel sachs?

Hornbostel-Sachs is a system for classifying Musical Instruments, developed by musicologists Erich Moritz von Hornbostel and Curt Sachs in the early 20th century. It categorizes instruments into four primary groups: idiophones (producing sound through the material itself), membranophones (using a vibrating membrane), chordophones (stringed instruments), and aerophones (instruments that produce sound by vibrating air). This classification system is widely used in ethnomusicology and music education to analyze and compare musical instruments across cultures.
