Module:Infobox ET

Module documentation[view] [edit] [history] [purge]

Note: Do not invoke this module directly; use the corresponding template instead: Template:Infobox ET.

This module depends on the following other modules: Module: ET Module: Infobox Module: Limits Module: Rational Module: Utils

This module automatically fills in information about a specified equal temperament tuning.
