Phenomenon was inspired by mysterious and unexplainable natural phenomena, such as the atmosphere and sensations of the Aurora Borealis, the Bolides, and especially the Naga Fireballs of Thailand. Prangcharoen's fascination with the energies of darkness and brightness inspires special timbres of the instruments and chaotic texture to create an impression of mystery. Phenomenon is also an exploration in sounds within other sounds, and the use of moving notes within sustained notes. The surface of the music is critical, and the distance between the instruments and dynamics (crescendo and diminuendo) are the main factors that create atmosphere and timbre.
