Key Takeaways
  1. 1 Dance can be generated from music using a structured approach.
  2. 2 Atomic movements are the building blocks of dance, making it easier to create complex choreography.
  3. 3 The proposed method improves the quality of generated dances, making them more natural and aligned with music.

Introduction

The paper discusses the importance of generating dance conditioned on music, emphasizing the need for structural organization in choreography. It critiques existing neural approaches for lacking segment-level coherence and proposes a new perspective that views dance as sequences of atomic movements.

Method

The method section describes the framework and processes used to generate dance movements from music, focusing on the segmentation and clustering of dance data into atomic movements.

Human Motion Generation

Recent advancements in multimodal models have spurred interest in human motion generation. The paper highlights the limitations of applying text-to-motion frameworks to dance, which requires artistic and compositional characteristics that are not captured by existing methods.

Music-to-Dance Generation

The section reviews advancements in generative models for music-to-dance generation, noting the dominance of larger music-motion datasets. It critiques existing methods for lacking process information and structural coherence, contrasting them with the proposed atomic movement approach.

Periodic Music Input

This section outlines the process of atomic movement planning and dance completion, detailing how the model utilizes full music input to create rhythmic and structurally coherent dance sequences.

Fig. 2: The framework of our method. We propose a two-stage pipeline. 1) Atomic movements planning: the Full-music-awared Atomic Movement Planner outputs the Atomic Movement Plan, allocating the atomic movement type, length and position. 2) Dance Completion: The Dance Completion Generator re-creates the atomic movements and generates the transitions between them.

We show samples on the right.
