Defining a drum map for a percussion instrument When you choose Drums, Percussion, or Snare Drum from the Instruments pop-up menu, METRO displays a Drum Map grid for that instrument type. This display derives names and note assignments from the currently selected drum set in METRO, with a maximum of sixteen drum assignments per staff. There are five fields in the drum map table: Pitch. The pitch for the chosen instrument. Name. This field displays the drum name. Head. The notehead assigned to the corresponding drum and pitch. Position. The staff position for that drum’s notation. Voice. The voice of a drum note.
