The melody of Hakka hill songs vary from area to area since the Hakka are widely spread in different regions of China and their dialect they speak differs in many respects. For example,
Meizhou, a well-known Hakka area in Guangdong Province once had several unique tunes in this region, likewise with the various tunes found in other areas of Guangdong such as
Xingning,
Wuhua,
Dabu,
Fengshun,
Jieyang,
Zijin,
Heyuan,
Huiyang and others in the north and west of Guangdong. Due to this phenomenon, this type of singing can also be referred as the
Jiu Qiang Shi Ba Diao (). The so-called nine airs are the
Hailu,
Sixian,
Raoping,
Fenglu,
Meixian,
Songkou,
Guangdong,
Guangnan and
Guangxi air. Likewise, the eighteen tunes are the
Pingban,
Shangezi,
Laoshange (also the
South Wind tune),
Siniange,
Bingzige,
Shibamo,
Jianjianhua (also the
Ancients in December tune),
Chuyizhao,
Taohuakai,
Shangshancaica,
Guanziren,
Naowujin,
Songjinchai,
Dahaitang,
Kuliniang,
Xishoujin,
Tiaomaijiu,
Taohuaguodu (also the
Chengchuange tune) and
Xiuxiangbao tune. However, there are actually more tunes than aforementioned, but the others are not recorded and so remain unknown. Despite all of the differences between their tunes, Hakka hill songs share a common feature which is that one Hakka hill song can be sung by any Hakka from other regions. There is no rigid rule of singing skills and the length of the tune depends on the singer's own arrangement. Hakka hill songs incorporate seventeen types of Hakka flat intonation and seven more types of oblique intonation. Each stanza consists of four lines, each with seven syllables and each line except the third often include flat intonation. == Example ==
