(a) Interlocking rhythms in gamelan occur when two or more parts play alternating notes or patterns that fit together to form a complete rhythmic or melodic line. [1]

No single player performs the entire melody or rhythm alone; instead, each player contributes specific notes at specific points, and the parts interweave to create a composite whole. This technique is sometimes called kotekan in Balinese gamelan, where two players alternate notes at high speed, one playing the "on" notes and the other the "off" notes. The result is a rapid, flowing line that would be difficult or impossible for one player to perform alone. Interlocking is a fundamental principle of gamelan music and reflects the communal, collaborative nature of the ensemble.

(b) The structural principle where the gong marks cycles is called colotomic structure. [1]

Colotomic structure is the system by which certain instruments in the gamelan punctuate specific points within a repeating rhythmic cycle. The gong ageng marks the most important structural point (the end of the cycle), while other instruments such as the kenong, kempul, and ketuk mark intermediate points. This layered punctuation creates a hierarchical rhythmic framework that organises the music and signals its formal structure to all players. The concept is analogous to poetic metre, where stressed syllables occur at regular intervals.

(c) The instrument that plays the core melody is the saron (also accepted: metallophone or balungan instrument). [1]

The saron is a metallophone with bronze bars laid over a wooden trough resonator. It plays the balungan (core melody or skeletal melody), which is the central melodic reference around which all other parts are built. Other instruments elaborate on the balungan: some play slower versions (the slenthem), some elaborate it with faster ornamental patterns (the gender, bonang), and the punctuating instruments mark the cycle's structure. The balungan is the melodic backbone that holds the entire performance together.
