The hexatonic scale is a six-note collection that conveys characteristics similar to theseven-note modes. Just like pentatonics, hexatonic scales have more interesting intervallicproperties and provide essential notes for melodic lines and harmonic formations. Thehexatonic collections are compartmentalized in the familiar categories and scales are gener-ated from aggregates of pitches that contain all available notes from the particular category.For instance, since the pitch aggregate for the major category contains eight notes, thereare a number of options for creating different major hexatonics. Given the enormous rangeof options, it is best to pick a scale whose pitch content best conveys specific modalcharacteristics.The derivation of hexatonics from the aggregate puts the understanding of pitch hierarchyto the test. The pitch structure of different hexatonics prioritizes only those notes thatare essential to projecting the exact harmonic function and/or intended chord–scalerelationship. Each category below includes two types of hexatonic collection: regular andaltered. Regular hexatonics share common characteristics with the corresponding modes.For instance, Mixolydian ≥11 hexatonic has similar properties to the seven-note Mixolydian≥11 mode, etc. Altered hexatonics are derived from the specific pitch aggregate and theirstructure includes minor variations from regular hexatonics. In labeling altered hexatonics,use the name of the category with Roman numerals specifying different variations (i.e.Major Altered I, Dominant Altered II, etc.)
