The 'Turks', the rulers of the Delhi Sultanate - were assimilated to such familiar categories as "yavana', "Ionian" - the term used to describe the Greek invaders who followed Alexander the Great a millennium before...relation to Ionian scale?

Ionia is a region along the western coast of Turkey.

Mode, latin for modus... in mensural notation, the relationship between the long and the breve.. any of the rhythmic patterns making up the set of rhythmic modes employed in certain repertoires of medieval music.. in the writings of some early medieval theorists, interval...

the essentials of the system of modes, termed church modes, used in the classification of gregorian chant were formulated by ca. 1000 .. eight modes are defined, each according to final, the intervallic relationship of other pitches to the final, the ambitus.. from this period onward, the final is regarded as the most important criterion of mode, through the gamut of diatonic pitches is a prior assumption, and thus the intervallic relationship of other pitches to the final is in large measure inseparable from the definition of the final itself...(four finals being d, e, f, and g)

some early sources tend to number the four finals in ascending order with terms derived from the Greek ordinal numbers ... protus, deuterus, tritus, and tetrardus, distinguishing plagal forms for each.

beginning in the late 15th century, theorists described polyphony in modal terms as well. it is in the context that the traditional system of 8 modes is expanded to 12 , first by Heinrich Glarean. He added authentic to plagal modes with finals on a and c. all modal theorists devoted attention to the set of cadential pitches appropriate to each mode... more difficult to establish is concern by composers for the supposed ethical or affective qualities of the modes. the 11th mode was termed 'Ionian'..the final being c.. the ambitus c-c... the tenor g. (there are also the aeolian and dorian modes... to keep in line with my point of having greek origin in music theory... my point is confusing and broad, yet makes perfect sense to me so just let me work this out)...
