עוד יישמע (A Treasury of Chassidic Song)

Hasidic music is the devotional and communal song tradition of Hasidic Judaism, centered on nigunim—repetitive, often wordless melodies intended to elevate the soul and intensify prayer. It spans meditative, slow pieces (devekut nigunim) and exuberant dance tunes (simcha nigunim) sung at tishes, weddings, and holidays. Historically shaped in Eastern Europe, Hasidic music blends Jewish liturgical modes and cantorial ornamentation with local folk and dance idioms. Performances are typically communal and participatory—built on call-and-response, cyclical repetition, and gradual emotional build-up—aimed not at virtuosity but at spiritual ascent and collective joy. In the modern era it also encompasses a popular "Hasidic pop" stream that adapts its melodic language to contemporary band formats.

Nigun is a Jewish devotional melody, most strongly associated with the Hasidic movement, that is sung without words and built from vocables (such as “yai-dai-dai,” “bim-bam,” or “oy-oy”). Repetition and gradual intensification are central: the same short phrase is cycled many times, gathering emotion, volume, and tempo as participants join. Musically, nigunim are modal and often draw on Ashkenazi synagogue modes and Eastern European folk idioms. Common scales include Ahava Rabbah (Freygish/Phrygian dominant), Adonai Malakh (Mixolydian flavor), Misheberakh (major), and Mogen Ovos (minor). Rhythms range from slow, free-meter dveykus (adhesive/meditative) nigunim to lively dance forms in 2/4 or 3/4 suited to communal circle dances. Nigun is primarily vocal and communal, but it can be supported instrumentally by fiddle/violin, clarinet, accordion, tsimbl (hammered dulcimer), and handclaps. Ornamentation (slides, sob-like krekhts, and sighing turns) reinforces its expressive, prayer-like character.
