─ 12 ─than that was analyzed.2. Gamelan PelegonganGamelan Pelegongan has the same 5-tone pelog scale as Gamelan Gong Kebyar, while the number of keys for metallophones Pemade and Kantilan is ve, i.e., different from Gamelan Gong Kebyar (10 keys). As mentioned in the previous report1), the popularity of new Gamelan Gong Kebyar made in the early 20th Century was high and a considerable number of Gamelan Pelegongans were modied to make Gamelan Gong Kebyar, or their bronze part was melted to make new Gamelan Gong Kebyar. Therefore, there are very few Gamelan Pelegongans that existed since early times (some were newly made during the revival boom in the 1980s, although the number is small because musical pieces can be played with Gamelan Gong Kebyar).Gamelan Pelegongan is a type of Gamelan basically used to accompany Legong dance and Barong dance. It is called Gamelan Bebarongan if it is used to accompany Barong dance only. Gamelan Pelegongan to play only instrumentals along with Trompong (the instrument consists of small gongs) to play a melody is called Gamelan Semar Pegulingan and is older than Gamelan Pelegongan, and many of them were transferred from the royal palace to the rural community in the 19th Century to the early 20th Century. Gamelan Semar Pegulingan has the same pelog scale with ve or seven tones. Only two sets with seven tones made in the early 20th Century currently remain, and many others have five tones. The composition of instruments is basically the same as Gamelan Pelegongan except Trompong.In this report, Gamelan Pelegongan, Gamelan Bebarongan, and Gamelan Semar Pegulingan with five tones used for Legong dance are all treated as Gamelan Pelegongan.3.

The target of analysis at this time includes the metallophones with a range of four octaves.For Gamelan Pelegongan, and a pelog scale with one octave consists of ve tones.Gender Rambat is a metallophone with 13 to 15 bronze keys (the number of keys is different depending on villages for older instruments, but is normally 14 for those that were made recently) to play a melody with mallets in both hands (Fig.2). A full set of Gamelan Pelegongan includes two Gender Rambats and two one-octave high Gender Rambat Barangans.They all have ve bronze keys with one octave other than Gender Rambat. There are four types of metallophones : Jegogan with the lowest octave (Fig.3), Jublag with the second lowest octave (Fig.3), Pemade with the third lowest octave and Kantilan with the highest octave (Fig.2). One set of Gamelan Pelegongan has two each of Jegogan and Jublag that are tuned by slightly shifting the pitch of the corresponding ve keys, creating interference beats. There are four instruments of both Pemade and Kantilan. Respectively, two of them create a pair and are tuned by Fig.1 Gamelan Pelegongan for ISIFig.3 Jegogan and JublagFig.2 Gender Rambat, Pemade and Kantilan
