A fractional-3-limit notation is a kind of musical notation built on a chain-of-fifths notation, used for notating EDOs when the EDO has no good mapping from just intonation, or to avoid favoring one such mapping over another. Fractional-3-limit notations may be contrasted with other kinds of chain-of-fifths notation for EDOs, such as the JI-based notations used for EDOs with good fifths in the Sagittal system, and the step-count notations used in the Ups and Downs system.
