Tones

There are five phonemic tones in Sichuanese: dark level tone, light level tone, rising tone, departing tone and entering tone (or checked tone). In some regions the checked tone of Sichuanese has been merged into another tone, which is very different from standard Mandarin, whose checked tone has been merged irregularly into the other four tones. According to Phonology of Sichuan dialect (四川方言音系), among all the 150 Sichuanese-speaking cities and counties, 48 keep the checked tone while the other 102 have only four tones. Particularly, in some sub-dialects of the Minjiang dialect (such as the Yingjing dialect), the departing tone has developed into two different tones: a colloquial tone (which is similar to the second tone as a characteristic of Ba-Shu: 平声似去) and a literary tone (which is the same as the Chengdu dialect).

The tone contours of the Sichuanese dialects are highly and quite different from those of Beijing Mandarin. In Sichuanese, the first tone (dark level tone) is a high level tone (like Beijing), the second tone (light level tone) is a low falling tone (the mirror image of Beijing), the third tone (rising tone) is a high falling tone and the fourth tone (departing tone) is a low or mid rising tone (interchanged compared to Beijing) and the fifth tone (entering tone) is mid or high if it's not merged, as shown in the chart below.

In the areas which keep the entering tone, the five tones of Sichuanese are nearly identical to the values of 5 of the 6 tones of the indigenous Southern Qiang language.
