Etymology

The name buzzard was first used by Herman Miller in 2004 for the full 7-limit alternative extension to 5-limit vulture. The porting of the name to the 2.3.7 subgroup was relatively late. In 2021 Xenllium proposed buzzardisma, and in 2025 it was decided that the 2.3.7-subgroup restriction of buzzard was canonical, which makes it buzzard comma. The corresponding name for the full 7-limit temperament was therefore buzzardsmic and the comma was therefore buzzardsma.
