ImproVisAR: designing augmented reality piano roll for teaching improvisation
摘要
Improvisation is an important skill in music instrument learning, but remains a less-taught topic in traditional piano education. To improvise effectively, learners must develop musical vocabulary, creative confidence, and comfort in performance. These demands make piano improvisation a complex teaching challenge where technology interventions may offer support. Prior short-term studies on augmented piano roll visualisations have shown promise for teaching sight-reading and motor coordination in novice students. However, how such approaches can support advanced learners in acquisition of improvisational skills remains under-explored. To address this gap, we present ImproVisAR, an interactive piano training system that teaches improvisation through augmented piano roll visualisations. Concepts and tools derived from a co-design process with improvisation experts are integrated as structured learning modes. We validated the system through a four-day controlled study (
