This figure compares how many MusicBrainz releases explicitly credit each instrument.

• The count comes from the MusicBrainz instrument page itself, using the linked releases view for that instrument.
• A release only counts when MusicBrainz has an instrument relationship recorded there, so this is about credited presence in that catalog, not every album ever made.
• Coverage is broad enough to be fun, but it still reflects the habits and blind spots of a volunteer music database.

Think of this as documented release footprint, not the final word on which instruments truly dominate music history.
