The serial interface and protocol are described at page 20 of the document:
https://innovative-technology.com/product-files/manuals/bv20-technical-manual.pdf
Parallel interface is described on page 14, and is probably simpler to implement, but uses more pins (well, between 3 and 10 pins, depending on your requirements) and only accepts 4 note types.
There is a Arduino-BV20 serial interfacing conversation at:
https://forum.arduino.cc/index.php?topic=125119.0
which might be useful re: electronics of connecting Arduino to BV20. Don't be put off by the first paragraph... Joe eventually gets it going
