Musical instruments can be broadly divided into two main groups: string instruments and percussion instruments. String instruments produce sound through vibrating strings, such as violins, guitars, and cellos. In contrast, percussion instruments generate sound by being struck, shaken, or scraped, including drums, tambourines, and marimbas. These classifications help to organize instruments by their sound production methods.
