การสร้างสรรค์ดนตรีพื้นบ้านอีสาน “ลายแมงภู่ตอมดอก” ในรูปแบบของวงดนตรีแจ๊สร่วมสมัย The Creation of Isan Folk Music ‘Maeng Phu Tom Dok’ Arranged for the Ensemble of Contemporary Jazz

Abstract

This creative work aims to 1) study the contemporary Isan folk music ‘Maeng Phu Tom Dok’ (Bees swarm flowers), 2) arrange ‘Maeng Phu Tom Dok’ in the form of an ensemble of contemporary jazz, and 3) disseminate the work in the form of a contemporary jazz ensemble from the creation of Isan folk music. It was found that ‘Maeng Phu Tom Dok’ is a folk melody of the Northeast created with five pentatonic scales, which can be interpreted in both five pentatonic majors and five pentatonic minors. The process of the creation can be divided into seven steps.

          Step 1: The main melodies were analyzed in the form of notes on the staff.

          Step 2: The form and structure were determined into the ternary form including ABA and the movement was divided into seven parts including the introduction, head in, interlude, chorus 1, chorus 2, head out, and outro.

          Step 3: The harmony was determined on keys A minor using the 7^th chord as a major. The tension chord and slash chord were used in the chord turnaround in the form of IVM7-iiim7-iim7-vim7, iim7-V7-IM7, VIM7-V7-IM7, IVM7-iiim7-vim7. The related scale and mode were selected in the improvisation and the modulation.

          Step 4: The time signature and rhythm were determined to be a 4/4 between a swing and shuffle with the tempo of the song was between 130-140 PBM.

          Step 5: The ensemble was determined to be a small band featuring all musical instruments, including the Pin (an Isan instrument), guitar, piano, keyboard, bass, and drums.

          Step 6: The role of musical instruments was determined. The sound of the Pin and the guitar led the main melody. The sound of the keyboard was the overtone, while the sounds of the drums, bass, keyboard, and guitar were the accompaniment. There was an improvisation between the Pin and guitar, including the improvisation trade of other musical instruments.

Step 7: The work was publicized under the title ‘Maeng Phu Tom Dok’ at the 5^th International Symposium on Creative Fine Arts (ISCFA) 2024 and on social media.
