The motet emerged from which two musical forms?

The motet emerged from organum and clausulae, making this the correct answer. Organum refers to a form of early polyphony where a plainchant melody is accompanied by one or more additional lines of music, creating harmony. This style was an early step towards more intricate vocal arrangements. Conversely, clausulae are sections of organum that were based on a single melodic line which could be sung independently. As the practice evolved, composers began to develop texts for these musical sections, leading to the creation of the motet as a distinct form characterized by multiple voices each with their own textual lines.

The other options do not accurately represent the roots of the motet. The ballade and madrigal are forms associated with Renaissance music and lyric poetry but do not directly contribute to the motet's origin. Similarly, the fugue and sonata are later developments in Western classical music that emerged well after the motet’s inception. Lastly, the antiphon and hymn are both types of liturgical music but lack the polyphonic features that define motets. Therefore, the connection between organum, clausulae, and the motet is rooted in the evolution of early polyphonic practices that shaped the way multiple melodic lines could interact while maintaining
