Pathet

The pathet (Javanese spelling; also patet) is an organizing concept in gamelan music. It is difficult to explain, but is similar to the melody types, that is, for example, modes, ragas, or maqamat, of other musics.

The term means 'to restrain' in Javanese and patet is "a limitation on the player's choice of variation, so that while in one patet a certain note may be prominent, in another it must be avoided, or used only for special effect. Awareness of such limitations, and exploration of variation within them reflects a basic philosophical aim of gamelan music, and indeed all art in central Java, namely, the restraint and refinement of one's own behaviour." Javanese often give poetic explanations of pathet, such as "Pathet is the couch or bed of a melody." In essence, a pathet indicates which notes are stressed in the melody, especially at the end of phrases (seleh), as well as determines which elaborations (cengkok and sekaran) are appropriate. In many cases, however, pieces are seen as in a mixture of pathets, and the reality is often more complicated than the generalizations indicated here, and depend on the particular composition and style.
