The Flower of Isan

Mor lam is a Lao and Isan (northeast Thailand) tradition of improvised sung poetry accompanied most characteristically by the khaen, a free‑reed mouth organ. Performers, known as mo lam, deliver long, melismatic lines that weave around a steady drone and interlocking rhythmic ostinatos. The genre is fundamentally narrative and dialogic: verses often unfold as call‑and‑response between singer and instrument or chorus, using poetic meters and witty, extemporized wordplay. Musically it favors pentatonic or anhemitonic scales, heterophonic textures, and flexible tempo that can accelerate for dance sections. In modern contexts, mor lam frequently integrates electric guitar, bass, keyboards, and drum kit, yielding high‑energy concert forms and the faster offshoot mor lam sing.
