Iconic notation is a system of invented symbols that students create themselves to represent sounds. Rather than using standard music notation — which requires years of dedicated study to read and write — students draw their own marks on paper that capture something about the sound they have made: its shape, its length, its volume, its character. A loud, low sound might become a thick, heavy line. A fast, fluttery sound might become a series of small dots. There is no universal system and no correct answer. What matters is that the symbol communicates the sound to the person performing it.

Iconic notation is developmentally significant because it builds the conceptual foundation for standard notation: the understanding that a mark on a page can represent a sound in time. Students who have invented their own notation system have already grasped the core idea behind all music literacy, which makes the transition to standard notation in the later grades considerably more intuitive.
