What does tonal rhythm refer to in music?

Tonal rhythm refers specifically to the rhythm that arises from the rhythmic properties of the tonal system. This concept connects the pitch and rhythm in a way that is tied to the traditional Western tonal music framework, where notes and their relationships create not only melodies but also specific rhythmic patterns. In this context, tonal rhythm emphasizes how the structure of tonal harmonies influences the rhythmic feel and movement of the music, allowing for a deeper understanding of how rhythm interacts with melody and harmony.

The other options, while related to aspects of rhythm and musical structure, do not accurately capture the essence of tonal rhythm. For example, rhythm dependent on meter focuses more on the organization of beats rather than how those beats interact with the tonal qualities of notes. Similarly, rhythm consisting of melodic intervals pertains more to pitch relationships rather than their rhythmic implications. Lastly, while rhythm characterized by frequent tempo changes addresses variations in speed, it doesn't reflect the foundational role of the tonal system in shaping rhythm.
