The project involved creating the graphic design and layout of the Duo Violas Brasileiras book, featuring musicians André Moraes and César Petená. The publication combines musical scores, photographic records, and texts that present the duo's journey and their involvement with research surrounding Brazilian violas. The layout of the musical scores was designed to offer a clear and functional reading experience, while also integrating with the book's visual language. The images highlight the instruments and moments captured throughout the musicians' careers.
