Percussion instruments that produce specific, steady tones and can be used to play melodies are categorized as

Percussion instruments that produce specific, steady tones and can be used to play melodies are categorized as "tuned percussion" or "pitched percussion." These instruments can produce pitches that are recognizable and can interact melodically with other instruments in music. Common examples of tuned percussion instruments include the xylophone, marimba, vibraphone, glockenspiel, and steel drums. Unlike untuned percussion instruments, which produce sound primarily based on their shape and material without a definite pitch, tuned percussion instruments have clearly defined musical notes, allowing for melodic and harmonic contributions in a musical composition. This categorization is important in music theory and composition, as it impacts how different instruments interact within a piece.
