and wearing pha sarong'' Isan has regional styles, but these are styles of performance rather than separate genres. The most important of the styles were
Khon Kaen and
Ubon, each taking their cue from the dominant form of
lam gon in their area: the '''' of Khon Kaen, with its role of displaying and passing on knowledge in various fields, led to a choppy,
recitative-style delivery, while the love stories of Ubon promoted a slower and more fluent style. In the latter half of the 20th century the Ubon style came to dominate; the adaptation of Khon Kaen material to imitate the Ubon style was sometimes called the
Chaiyaphum style. The
Lao regional styles are divided into the southern and central styles (
lam) and the northern styles (
khap). The northern styles are more distinct as the terrain of northern Laos has made communications there particularly difficult, while in southern and central Laos cross-fertilisation has been much easier. Northern Lao singers typically perform only one style, but those in the south can often perform several regional styles as well as some genres imported from Isan. The main Lao styles are: •
Lam Sithandone (ລຳສີທັນດອນ, ลำสีทันดร) (also called
Lam Si Pan Don [ລຳສີພັນດອນ, ลำสีพันดอน]), from Champassak is similar in style to the
lam gon of Ubon. It is accompanied by a solo khene, playing in a
san mode, while the vocal line shifts between
san and
yao scales. The rhythm of the vocal line is also indeterminate, beginning in speech rhythm and shifting to a metrical rhythm. •
Lam Som (, ) is rarely performed and may now be extinct. From Champassak, the style is hexatonic, using the
yao scale plus a supertonic C, making a scale of A-B-C-D-E-G. It uses speech rhythm in the vocal line, with a slow solo khene accompaniment in meter. It is similar to Isan's ''
. Both Lam Som
and Lam Sithandone'' lack the descending shape of the vocal line used in the other southern Lao styles. •
Lam Khon Savane (ລຳຄອນສະຫວັນ, ลำคอนสะหวัน, ) from Savannakhet is one of the most widespread genres. It uses the
san scale, with a descending vocal line over a more rigidly metrical ensemble accompaniment.
Lam Ban Xoc (ລຳບ້ານຊອກ, ลำบ้านซอก, ) and
Lam Mahaxay (ລຳມະຫາໄຊ, มหาไซ, ) are musically very similar, but
Ban Xoc is usually performed only on ceremonial occasions while
Mahaxay is distinguished by a long high note preceding each descent of the vocal line. •
Lam Phu Thai (ລຳຜູ້ໄທ, ลำผู้ไท, ) uses the
yao scale, with a descending vocal line and ensemble accompaniment in meter. •
Lam Tang Vay (ລຳຕັງຫວາຍ, ลำตังหวาย, ) is a Lao version of
Mon-Khmer music, with a descending ensemble accompaniment. •
Lam Saravane (ລຳສາລະວັນ, ลำสาละวัน [ลำสุวรรณ], ) is also of Mon-Khmer origin. It uses the
yao scale. The descending vocal line is in speech rhythm, while the khene and drum accompaniment is in meter. •
Khap Thum Luang Phrabang (ຂັບທຸ້ມຫລວງພະບາງ, ขับทุ้มหลวงพระบาง, ) is related to the court music of
Luang Phrabang, but transformed into a folk-song style. The singer and audience alternately sing lines to a set melody, accompanied by an ensemble. •
Khap Xieng Khouang (ຂັບຊຽງຂວາງ, ขับเซียงขวาง, ) also called
Khap Phuan (ຂັບພວນ, ขับพวน) uses the
yao scale and is typically sung metrically by male singers and non-metrically by women. •
Khap Ngeum (ຂັບງຶມ, ขับงึม, ) uses the
yao scale. It alternates declaimed line from the singer and non-metrical khene passages, at a pace slow enough to allow improvisation. •
Khap Xam Neua (ຂັບຊຳເໜຶອ, ขับซำเหนือ, ) uses the
yao scale. Singers are accompanied by a solo khene, declaiming lines each ending in a cadence. •
Khap Tai Dam (ຂັບໄທດຳ, ขับไทดำ, ) used for
Tai dam people. Below is a comparative table of regional
mor lam styles, sourced from Compton (1979). ==Performers==
