The Lanna Symphonic Poem for Wind Symphony is a piece of program music. The composer has revived some of the historical and cultural happenings of the northern part of Thailand: Poyluang Festival, King Kawila, Ping River, Khong Gate, and Tapae Gate to encourage the perpetuation of the remembrance of these events. The Symphonic Poem written for a wind symphony comprises 5 movements. The approximate duration is 20 minutes. The composition is mostly in tonal system, with some paratonal technique, to suit the programmatic musical ideas. Some movements contain Thai music elements to act as bridges of passages representing those events; in addition, well-known folk melodies taken from several sources are inserted. Important elements used in the composition are motives, along with intervals and chords resulting from certain notes derived from motives. Intervals of 3rd, 4th, 5th, quartal chord, quintal chord and secundal chord, are employed throughout the composition, with the use of polytonality occasionally. The texture includes homophony, polyphony and heterophony. Juxtaposition of chords is apparent along with repetitions, imitations, sequences, inversions and retrogrades. Changing of time signatures from simple time to compound time and to complex time occurs from time to time.
