Pelog is one of the two essential scales of Gamelan music native to Bali and Java, in Indonesia. The other is slendro. A gamelan is a musical ensemble of Indonesian origin typically featuring metallophones, xylophone(s), drums, and gongs. ... Bali is an Indonesian island. ... View of the Puncak area in West Java Java (Indonesian: Jawa) is the most populous of Indonesias islands, and the site of its capital city, Jakarta. ... Slendro (called salendro by the Sundanese) is a pentatonic (five tone) scale, one of the two most common scales used in Indonesian gamelan music. ...

Pelog scales can and do vary widely from island to island, province to province, and even town to town (Bali is a good example of where this happens). There is disagreement among musicologists about what exactly makes a pelog scale a pelog scale. It has been only fairly recently that attempts have been made to characterize the scale in terms of its physical pitch values. Moreover, a complete understanding of the pelog scale cannot result merely from an accurate physical characterization; perhaps even more important is an understanding of the function of this scale in the music, and in the culture in which the music is performed.

A full pelog scales is seven tones. However, many instruments only have five tones. Even when instruments have all seven tones, more often than not only five of the tones will be used in a scale. In this respect the pentatonic pelog scale can be thought of as a mode. In music, a pentatonic scale is a scale with five notes per octave. ... Mode has several meanings: In statistics, the mode is the value that has the largest number of observations, namely the most frequent value or values. ...

The Pelog scale in some parts of Java can be constructed in the same way as the Western diatonic scale, as a chain of perfect fourths, except with very wide, out-of-tune fourths, between 515 and 535 cents. This is at the very extreme of the range of intervals that can be perceived as a fourth, and rapid beating between the upper harmonics (actually inharmonic overtones in the case of the metallophones which form the bulk of the gamelan orchestra) contributes to the unique shimmering sound of the gamelan. The full pelog scale has seven distinct tones (a stack of six fourths), but normally a composition would be written in a five-tone subset of the full scale. The seven tones of the pelog scale, in circle-of-fourths order, are called "barang", "dada", "nem", "gulu", "lima", "bem", and "pelog" (the latter note bears the same name as the scale as a whole). Therefore, the tones of the scale in ascending order, with the two different kinds of step interval labeled L and S, are: gulu-S-dada-L-pelog-S-lima-S-nem-S-barang-L-bem-S-gulu. In this case S is about 110-150 cents and L is 250-300 cents. In Music theory, the diatonic major scale (also known as the Guido scale), from the Greek diatonikos or to stretch out, is a fundamental building block of the European-influenced musical tradition. ... The musical interval of a perfect fourth, often P4, is the relationship between the first note (the root or tonic) and the fourth note (subdominant) in a major scale. ... The cent is a unit in a logarithmic scale of relative pitch or intervals. ... In music theory, an interval is the difference (a ratio or logarithmic measure) in pitch between two notes and often refers to those two notes themselves (otherwise known as a dyad). ... Beating is striking more than once, in violence, beating a drum, etc. ... In acoustics and telecommunication, the harmonic of a wave is a component frequency of the signal that is an integral multiple of the fundamental frequency. ... In music, inharmonic refers to the degree to which the frequencies of the overtones of a fundamental differ from whole number multiples of the fundamentals frequency. ... An overtone is a sinusoidal component of a waveform, of greater frequency than its fundamental frequency. ... Generally speaking, a metallophone is any musical instrument consisting of tuned metal bars which are struck to make sound, usually with a mallet. ... A gamelan is a musical ensemble of Indonesian origin typically featuring metallophones, xylophone(s), drums, and gongs. ... Orchestra at City Hall (Edmonton). ... In music theory, the circle of fifths is a model of pitch space and is the series encompassing all of the notes in the equally tempered chromatic scale. ...
