ABSTRACT
The art of singing Keroncong is commonly taught informally, directly by a Keroncong maestro. This makes the development of Keroncong as a vocal art highly dependent on the availability of Keroncong maestros. Vocal exercise books are rarely found in the library. It creates a limited access for young generations to learn Keroncong. This research aimed to produce a learning material by exploring the benefits of Luk Keroncong. Using a design-based research method, we analyzed the characteristics of Luk Keroncong, constructed vocal exercises and implemented them on a vocal class. Research participants were music education students from Indonesia University of Education. Responses and comments from students were collected, and used to refine the vocal learning materials. It was indicated that luk is somewhat similar to portamento. Vocal technique exercises using Luk Keroncong were able to facilitate students to master breath support, passagio and head voice.
