As its name might imply, Harmonium is a musical with its protagonist’s love of music being its central core. Interestingly, the protagonist in the game is deaf, communicating entirely through sign language. The character’s attempts at playing musical instruments also involve a heavy visual component, making use of glitter to distinguish between the sounds of different drums.

The plot seems to kick off, however, when the protagonist gets pulled into a mystical world through a book. The trailer doesn’t show too much in the way of gameplay, however, opting to showcase its world and characters as they communicate with each other without the use of spoken words.

Harmonium The Musical seems to take quite a bit of influence from fairy tales, as is evident with the presence of the mythical creatures in the trailer.
