*''Constraint 2'': The musical surface must be available for [[hierarchical]] structuring by the listening grammar.

**[through grouping structure, metrical structure, time-span reduction, prolongational reduction, "associational" factors such as [[Motif (music)|motivic]] development and [[timbre|timbral]] relations are ignored, however for "Timbral Hierarchies" see Lerdahl 1987]
