An Analysis of Ranad Ek Melodic Patterns for Classifying Performance Complexity Levels

Abstract

This research consists purposes were 1. to analyze and classify the levels of performance complexity in Ranad Ek (Thai xylophone) melodic pieces (Glon), covering 9 categories comprising 10 pieces and 2. to serve as a guideline for designing a basic Ranad Ek instructional manual for students at the foundational level, in alignment with Learning Standard Art 2.1 of the Arts Learning Area under the Basic Education Core Curriculum B.E. 2551 (2008). This is a qualitative research study, using a Ranad Ek melodic composition analysis form as the research instrument, which was validated for content validity by experts. The data were then analyzed using content analysis. The findings revealed that 1) the complexity of Ranat Ek melodic patterns can be categorized into five distinct levels based on structural characteristics and physical playing techniques: Level 1 (least complex) consists of Glon Sap 2, Glon Tai Luat and Glon Doen Takhep (or Muan Takhep) Level 2 includes Glon Tai Mai, Glon Yon Takhep and Glon Son Takhep; Level 3 is represented by Glon Sap 1; Level 4 comprises Glon Roi Lukso and Glon Phan and Level 5 (most complex) is identified as Glon Lot Takhai. Structural variations in length, register and note frequency across these levels correspond directly to specific performance techniques. These insights provide a foundational model for sequencing curriculum contents in Ranat Ek instructional manuals for lower secondary school beginners, effectively resolving uneven striking issues (Khayok) and cultivating advanced melodic variation skills and 2) The classification of complexity into 5 levels can be applied as a normative framework for logically sequencing content and learning activities in music education for beginner-level students. Instruction should begin with Level 1 pieces to help develop the physical technique of controlling wrist mechanics, build consistent and even hand weight and precisely address the deficiency known as khayok (unsteady, uneven tone production), before progressing to practicing melodic variation (Glon prae) pieces at higher levels in accordance with the learner's development. This serves as an essential foundation for systematically cultivating students' musical improvisation skills and advanced melodic variation ability in a stepwise manner.
