Neutral Clef or "Percussion Clef"
There is a percussion clef, which is two short vertical lines at the beginning of the staff.
Some percussion instruments may, and some may not. Usually if something like a drum has tuning equipment, it may be tuned to whatever pitch you desire.
The difference is that pitched instruments play notes, whereas non pitched instruments do not. Example, there are many non pitched percussion instruments, like snare drums, but drums such as timpani's actually play notes and can be adjusted, making them pitched. All woodwind brass and string instruments are considered pitched.
Non-pitched percussion instruments are used for a few reasons, providing a beat and a cool backbone to the song. Pitched percussion instruments are usually used for harmony or the melody of a song, they don't have that backbeat that a snare or a bass has, and a snare and a bass don't have the melody to the song, such as a Marimba would.
A pitched percussion instrument play numerous pitches (i.e. xylophone), while nonpitched percussion instruments play one pitch (i.e. snare drum).
Pitched percussion instruments produce definite pitches or specific musical notes when struck, such as xylophones or marimbas. Unpitched percussion instruments, on the other hand, produce indefinite pitches or non-specific musical notes, like cymbals or snare drums. The key distinction lies in the ability of pitched percussion instruments to play melodies and harmonies, while unpitched percussion instruments are primarily used for rhythm and texture.
For the most part if they have keys like the piano or bells then yes. Timpani are also tuned to certain notes before they are played. Drums though, like snare and bass, do not play different pitches.
Any percussion that can't be tuned is non pitched. cowbells, triangle, tambourine
A vibraphone is a pitched percussion instrument.
Some percussion instruments that do not produce definite pitches include the snare drum, bass drum, and tambourine. These instruments create sound through the vibration of the instrument itself or the impact of a material on the instrument, resulting in a non-pitched or indeterminate sound.
