  1. Age, non-verbal IQ (SPM, IQ values), information processing capacity (ZVT, IQ values), musical training (total hours during life span on main instrument in hours), musicality (AMMA total, raw score on test; AMMA tonal, tonal raw score; AMMA rhythmic, rhythmic raw score; MSI, questionnaire, sum score; higher values indicate higher musicality), and online pitch identification screening (PIS, sum of correctly named tones) for each group. No group differences apart from performance on pitch-naming test (PIS) were found
  2. *Two RPs reported not having absolute pitch but reached a screening score of 13 and 21, respectively. Because of this and their weak performance in the pitch adjustment test, the subjects were assigned to the RP group. Significant group differences are indicated in italics
