Such languages differ in which tone is marked and which is the default. In [[Navajo language|Navajo]], for example, syllables have a low tone by default, while marked syllables have high tone. In the related language [[Sekani language|Sekani]], however, the default is high tone, and marked syllables have low tone.<ref>{{chúChú thích web|url=http://people.umass.edu/jkingstn/web%20page/research/athabaskan%20tonogenesis%20camera%20ready%20final%2021%20october%2004.pdf|titletiêu đề=The Phonetics of Athabaskan Tonogenesis|lasthọ 1=Kingston|firsttên 1=John|yearnăm=2004|work=Athabaskan Prosody|publishernhà xuất bản=John Benjamins Press|pagescác trang=131–179|accessdatengày truy cập = ngày 14 tháng 11 năm 2008}}</ref> There are parallels with stress: English stressed syllables have a higher pitch than unstressed syllables, whereas in [[Tiếng Nga]], stressed syllables have a lower pitch.
