It takes just a fraction of a second for data to travel between the two coasts of the United States, but that is long enough to make it impossible for musicians to play a live duet over the internet — each musician hears notes from their partner that are roughly one sixteenth note late. Stagecast Piano Project plans to use machine learning to predict what notes each partner will play and create a projected partner audio feed for each musician. The team’s goal is to stage a live, four-hand, bicoastal piano duet within a year and ultimately to enable a wide variety of online musical collaborations that are currently impossible.
