Percussion instrument can be grouped into two categoriespitched and un pitched. what is the difference?

Pitched percussion instruments produce definite musical notes and can be tuned to specific frequencies, allowing them to play melodies; examples include the xylophone and marimba.

The distinction lies in the ability to create identifiable pitches versus non-pitched sounds.
