Mapping sound frequencies to the vertical axis is universal across humans
While many studies report a widespread cross-modal correspondence mapping high auditory pitch to vertical height and low pitch to depth, cultural differences, musical training, and individual variability indicate that this mapping is not strictly universal.
The claim asserts that mapping sound frequencies (pitch) to the vertical axis is universal across humans. The retrieved papers confirm a strong and pervasive cross-modal correspondence (e.g., papers 2, 6, 11), often reinforced by linguistic metaphors. However, papers like 6 and 10 highlight that musical training, cultural context, and individual differences introduce considerable variability, showing that not all humans map pitch vertically in the same way or to the same degree, making the claim contested rather than strictly universal.

Demonstrates that participants associate high-pitched tones with upper spatial locations and low-pitched tones with lower locations.

Notes that the strength of this cross-modal correspondence varies across cultural contexts, with musically trained participants showing more diverse or incongruent behaviors.

Shows that untrained speakers systematically make vertical, language-congruent movements corresponding to auditory pitch height.

Observes that while a majority show monotonic correlation, a significant portion of participants demonstrate alternative mapping patterns or inverse correlations.
