As in the main traditional theatrical forms in Southeast Asia, melodic percussion, wind and string instruments accompany the music on Volume 1 of SERU.
Percussion includes various gongs and drums. The gongs or tawak are suspended from wooden frames and each is tuned differently. The gedumbak, a single-sided drum, is the lowest-tuned drum with the longest sustain due to an opening on one end. The gendang is a double-sided hand drums while the geduk rests on a stand and struck with sticks on one side.
The kesi are small cymbals usually played in a set of two pairs. Two are fixed face-up and two hand-held. The canang, on the other hand, is a series of horizontally arrayed small gongs and can played both rhythmically or as a melody.
The serunai is a double-reed wind instrument. The player uses circular breathing techniques to create continuous melodic lines.
Finally, the rebab is a three-string spike fiddle and the main instrument of the Makyong theatre, a unique Malay traditional form of theatre.
