Since 2017 an ongoing creative project with The Piano Shop in Bath has offered Julieann Worrall Hood the opportunity to explore shaping sound through the language of sculpture, using scrap piano parts as her raw material. Her sculpture installation Joyful Sound is made out of over 1000 piano keys. It flows through the ground floor display windows of the three Georgian buildings that make up The Piano Shop in central Bath.

In 2019, 2021 and 2022 Worrall Hood also collaborated with the Piano Shop team to create pieces for Coldplay for international performances, bringing together traditional piano making with sculpture and textiles.

Worrall Hood continues to collaborate with artists, makers and musicians on new iterations of this window installation, creating temporary interventions with this contemporary, sustainable artwork.
