Gense /ʒense/ Theory is a fictitious alternative music theory popularized in the fictional nation of Córdua.  As such, the concepts discussed here, and the history thereof, should be understood to be fictitious, and therefore not necessarily applicable to the real world.

While in theory, the Genses are said to represent certain underlying [[Just intonation|Just Intonation]] intervals, in practice the actual realizations thereof differed from place to place, and from person to person.
While in theory, the Genses are said to represent certain underlying [[Just intonation|Just Intonation]] intervals, in practice the actual realizations thereof differed from place to place, and from person to person.  Theorists and practitioners throughout the Renaissance made various claims on the fewest number of intervals necessary to accurately represent all nine Genses (see below); these numbers ranged from as few as 9 to as many as 20 unique notes between the root and the Perfect Fifth.


During the Romantic period, fixed-pitch instruments such as keyboards and fretted strings became some of the most popular styles of instrumentation, which led equal-step tunings to be more desirable for the purposes of transpositional invariance.  While systems of [[12edo|12]], [[19edo|19]], [[31edo|31]], [[41edo|41]], and more were all suggested and experimented with from the Renaissance onwards, [[17edo|17 Equal Divisions of the Octave]] ended up dominating by the modern era; this system was able to represent the Genses accurately enough to be recognizable to nearly all musicians and listeners, while also being small enough to be consistently manageable on instruments such as guitars and claviers.

In Córduan tradition, a Maqam (plural: Maqames) is a sequence defined by having a specific ''Yeti Gense'', or a Gense on its root note that defines the tone of the Maqam.  Any other Genses used to complete the scale are known as ''Pati Genses'', and always have their roots on the fourth or fifth of the ''Yeti Gense''.  While there exist some conventions concerning which ''Pati Genses'' are commonly used over which ''Yeti Genses'', there is no official standard that indicates any combination as illegal.
