I find a lot of analogies in the processes of learning calligraphy and learning to play a music instrument, but it maybe just a personal perception. The overlapping of music and chess seems more evident, as both have a mathematical foundation. In the 18th century François-André Danican Phillidor excelled in composing music and playing chess. I am not sure if today's chess players know anything about his music compositions or if music lovers are aware about his chess career. We are too overspecialized to think something like that is even possible.
The other day Paul Antonio posted a video in Instagram, where he sings Gregorian chant while writing in textura, connecting the rhythm of the music with rhythm of the letters. I think is worth a watch.
