The choice of musical instrument matters: Effect of pitched but not unpitched musicianship on tone identification and word learning

Abstract The present study investigated the differential effects of pitched and unpitched musicianship on tone identification and word learning. We recruited 44 Cantonese-pitched musicians, unpitched musicians, and non-musicians. They completed a Thai tone identification task and seven sessions of Thai tone word learning. In the tone identification task, the pitched musicians outperformed the non-musicians but the unpitched musicians did not. In session 1 of the tone word learning task, the three groups showed similar accuracies. In session 7, the pitched musicians outperformed the non-musicians but the unpitched musicians did not. The results indicate that the musical advantage in tone identification and word learning hinges on pitched musicianship. From a theoretical perspective, these findings support the precision element of the OPERA hypothesis. Broadly, they reflect the need to consider the heterogeneity of musicianship when studying music-to-language transfer. Practically, the findings highlight the potential of pitched music training in enhancing tone word learning proficiency. Furthermore, the choice of musical instrument may matter to music-to-language transfer.
