Editing Absolute pitch (section)

===Linguistics===
Absolute pitch is more common among speakers of [[tonal language]]s, such as most dialects of [[Chinese language|Chinese]] or [[Vietnamese language|Vietnamese]], which depend on pitch variation to distinguish words that otherwise sound the same—e.g., [[Standard Mandarin|Mandarin]] with four possible tonal variations, [[Cantonese]] with nine, [[Southern Min]] with seven or eight (depending on dialect), and [[Vietnamese language|Vietnamese]] with six.<ref name=jasa138th>{{cite journal |last1=Deutsch |first1=D. |last2=Henthorn |first2=T. |last3=Dolson |first3=M. |title=Tone Language Speakers Possess Absolute Pitch |journal=The Journal of the Acoustical Society of America |year=1999 |volume=106 |issue=4 |page=2267 |url=http://www.acoustics.org/press/138th/deutsch.htm |doi=10.1121/1.427738 |bibcode=1999ASAJ..106.2267D |access-date=August 16, 2007 |archive-date=October 14, 2007 |archive-url=https://web.archive.org/web/20071014151404/http://acoustics.org/press/138th/deutsch.htm|url-access=subscription }}</ref><ref name=jasa148th>{{cite journal | last1 = Deutsch | first1 = D. | last2 = Henthorn | first2 = T. | last3 = Marvin | first3 = E. | last4 = Xu | first4 = H. | title = Perfect Pitch in Tone Language Speakers Carries Over to Music | journal = The Journal of the Acoustical Society of America|year= 2005 | volume = 116 | issue = 4 | page = 2580 | doi = 10.1121/1.4808626 |bibcode = 2004ASAJ..116.2580D}}

Many native speakers of a tone language, even those with little musical training, are observed to sing a given song with consistent pitch. Among music students of East Asian ethnic heritage, those who speak a tone language fluently have a higher prevalence of absolute pitch than those who do not speak a tone language.<ref name="phil-jasa-2006">{{cite journal |author=Deutsch, D. |author2=Henthorn, T. |author3=Marvin, E. |author4=Xu H-S |name-list-style=amp|title=Absolute pitch among American and Chinese conservatory students: Prevalence differences, and evidence for a speech-related critical period |journal=The Journal of the Acoustical Society of America|volume=119 |pages=719–722 |year=2006 |doi=10.1121/1.2151799 |pmid=16521731 |issue=2|bibcode = 2006ASAJ..119..719D | url=http://philomel.com/pdf/JASA-2006_119_719-722.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://philomel.com/pdf/JASA-2006_119_719-722.pdf |archive-date=October 9, 2022 |url-status=live}}</ref><ref name="deu-2009">{{cite journal |author1=Deutsch, D. |author2=Dooley, K. |author3=Henthorn, T. |author4=Head, B. |title=Absolute pitch among students in an American music conservatory: Association with tone language fluency |journal=The Journal of the Acoustical Society of America|volume=125 |pages=2398–2403 |year=2009 |doi=10.1121/1.3081389 |pmid=19354413 |issue=4|bibcode = 2009ASAJ..125.2398D | url=http://philomel.com/pdf/JASA-2009_125_2398-2403.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://philomel.com/pdf/JASA-2009_125_2398-2403.pdf |archive-date=October 9, 2022 |url-status=live}}</ref><ref name="phil-588">{{cite journal |author1=Deutsch, D. |author2=Li, X. |author3=Shen, J. |name-list-style=amp | title=Absolute pitch among students at the Shanghai Conservatory of Music: A large-scale direct-test study | journal=The Journal of the Acoustical Society of America| volume=134 |issue=5 | pages=3853–3859 | year=2013 | doi=10.1121/1.4824450 |pmid=24180794 |url=http://philomel.com/pdf/JASA_2013_134_3853-3859.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://philomel.com/pdf/JASA_2013_134_3853-3859.pdf |archive-date=October 9, 2022 |url-status=live|bibcode = 2013ASAJ..134.3853D}}</ref>
