1 equal division of the octave (abbreviated 1edo or 1ed2), also called 1-tone equal temperament (1tet) or 1 equal temperament (1et) when viewed under a regular temperament perspective, is the tuning system that uses equal steps of 2/1 (one octave), or exactly 1200 ¢.
Notation
A. All A.
Theory
All intervals are either tempered out or mapped to the octave.
