About this Research Topic

Background

Both language and music are evolutionarily old and ubiquitous in human cultures. Conventionally studied as two separate domains, language and music share close parallels such as the use of basic acoustic attributes like pitch and duration, the presence of complex hierarchical structures and the ability to elicit and communicate emotions in people. These parallels have evoked important questions regarding the neural organization of language and music, the cross-domain transfer between them, and their evolutionary relationship. However, the language-music remains controversial. While some theories hold that language and music are two separate domains with minimal influence from each other, others posit that language and music share processing resources and may even have descended from a common evolutionary origin. Early genetic studies have shown that FOXP2 gene is directly implicated in the etiology of speech and language disorders and song birds with reduced brain FOXP2 expression have problems with learning songs.

The advance of neuroimaging techniques, genetic analyses, and emerging new evidence have provided a timely opportunity to revisit the language-music relationship. There has been mounting evidence for the cross-domain transfer of language and music, such as the benefit of musicianship, musical training or musical therapy on certain aspects of language processing, learning or recovery, and the negative impact of musical disorder on certain aspects of language processing, which exemplifies the music-to-language transfer. In the other direction (language-to-music), it has been found that tonal language experience boosts certain aspects of musical abilities. However, many issues remain unresolved, especially the mechanism and neural underpinning of such transfer. The neural organization of language and music also remains controversial. Traditionally, language and music are believed to predominantly involve the left and right hemisphere respectively, but there is evidence that their neural circuitries partially overlap. Subcortically, long-term experience with language and music similarly enhances sensory processing and the benefit appears to transfer between the two domains. Furthermore, certain processes in music are found to recruit the same brain processes and regions involved in language processing. Nonetheless, refined analysis of focal brain regions has reported substantial non-overlap between the processing of language and music.

In this Research Topic, we welcome contributions that address the relationship of language and music from a wide range of perspectives, including but not limited to evolutionary biology, genetics, behavioral sciences, cognitive neuroscience, and musicology, in a wide range of participants from children to the elderly, from healthy individuals to individuals with acquired or developmental disorders of music or language, and in diverse language contexts, including tonal and non-tonal languages. Studies that elucidate the fine-grained overlap and non-overlap of language and music processing from subcortical to cortical neural circuitries will also be welcome. We encourage authors to submit empirical research, systematic reviews and meta-analysis, case studies, or papers with new theoretical perspectives. We hope these contributions will generate new insights into the cognitive, neural, genetic and evolutionary relationship of language and music.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
