In the InCHORRRuS (Infant-directed (ID) Communication Highlights and Organizes Repetition and Redundancy through Rhythmic Structure) framework, increased rhythmicity in ID speech and the beat-based metrically structured rhythmicity in ID song naturally organize the multimodally redundant and repetitive cues in the caregiver's communicative signals, supercharging their saliency by increasing their predictability. Rhythmicity naturally modulates infant attention, guiding it to those communicatively rich times and scaffolding caregiver-infant coordination.
