Traditional Newar music has been arranged into a particular schedule. One of the dominant forms of traditional Newar music is Dapha music. Dapha music is classical Newar music that probably originated during late Lichhavi period and flourished in the Malla period. Basically, the songs of Dapha music are devotional songs based on classical ragas. Dapha music is played by bands known as Dapha Khalah that may be associated with traditional groups called Guthi. According to the ragas, certain songs are played at certain seasons or times of the day. The songs generally narrate or depict the mood of a particular season. Besides the seasonal and scheduled ragas, various ragas are played during specific events, such as Deepak raga (played when a monarch passes away).
