2-3 Weeks. Songful Hearts presents an enlightening and enjoyable look at the traditional music and culture of Cambodia, and particularly how it is thriving today in communities outside of Cambodia. Featuring personal comments by Sam-Ang, a living archive of Khmer music and culture, on each selection, the book includes a wide variety of songs and instrumental pieces, from children's lilting etiquette songs, game songs and dances to beginning drum, xylophone and flute pieces, to exciting boxing music and stories told through song and narration.
