  Learning to play an instrument is intrinsically multimodal, and we have seen
a trend of applying visual and haptic feedback in music games and
computer-aided music tutoring systems. However, most current systems are still
designed to master individual pieces of music; it is unclear how well the
learned skills can be generalized to new pieces. We aim to explore this
question. In this study, we contribute Interactive Rainbow Score, an
interactive visual system to boost the learning of sight-playing, the general
musical skill to read music and map the visual representations to performance
motions. The key design of Interactive Rainbow Score is to associate pitches
(and the corresponding motions) with colored notation and further strengthen
such association via real-time interactions. Quantitative results show that the
interactive feature on average increases the learning efficiency by 31.1%.
Further analysis indicates that it is critical to apply the interaction in the
early period of learning.
