Two sets of percussion instruments made into three different culm sizes such as 26, 28 and 30 inches. Each node has a diameter of 6, 6.5 and 7 cm respectively. The wall measures approximately .5 mm thick suitable thickness to absorb the hit of the wooden/bamboo stick. The heavier the hit the louder the sound it produces.

Science in a creative industry.
The DOST-FPRDI has a Bamboo Musical Instruments Innovation R&D program aimed at improving the quality of locally-made bamboo musical instruments (BMIs) through science and innovative technologies. The program seeks to standardize the production of selected BMIs, develop prototype designs, analyze raw material sources and existing markets, and build a BMI processing facility. In addition, the program aims to document the ethnocultural story behind several BMIs and identify the bamboo species used in BMI production to promote public awareness and appreciation of the cultural importance of these musical instruments. The program is a collaboration with the University of the Philippines and Philippine Normal University for teaching modules and analyzing sound quality and standardization of BMI design. The DOST Grants-in-Aid program provides funding.
