  For around 300 years, humans have been learning to play the modern piano
either with a teacher or on their own. In recent years teaching and learning
have been enhanced using augmented technologies that support novices. Other
technologies have also tried to improve different use cases with the piano,
such as composing and performing. Researchers and practitioners have showcased
several forms of augmentation, from hardware improvements, sound quality,
rendering projected visualizations to gesture-based and immersive technologies.
Today, the landscape of piano augmentations is very diverse, and it is unclear
how to describe the ideal piano and its features. In this work, we discuss how
the human-centered piano -- the piano that has been designed with humans in the
center of the design process and that effectively supports tasks performed on
it -- can support pianists. In detail, we present the three tasks of learning,
composing, and improvising in which a human-centered piano would be beneficial
for the pianist.
