What musical instrument category?

Musical Instruments are typically classified into four main categories: strings, woodwinds, brass, and percussion. String instruments, like violins and Guitars, produce sound through vibrating strings. Woodwind instruments, such as clarinets and flutes, generate sound by air passing through a reed or an opening. Brass instruments, like trumpets and trombones, create sound through the vibration of the player's lips in a mouthpiece, while percussion instruments, such as drums and cymbals, produce sound when struck or shaken.
