With a full piano each note of a melody can be any of 88 available pitches. Of course it’s not always possible to perfectly recover the original melody once it passes through the encoder and decoder. By connecting the encoder and decoder together the melody passes through a sort of funnel. The decoder reverses the process by taking this simplified sequence and outputting a melody that once again uses the different 88 notes a piano can produce. The encoder receives a melody (a sequence of notes) represented as the numbers 1-88 (the keys of the piano) as input and produces a sequence with the same length but using only the numbers 1 through 8. The Piano Genie AI was built by first creating two separate neural networks: an encoder and a decoder. They’re used for a very large variety of tasks such as image and voice recognition, playing games, developing drugs and vaccines, driving cars, or even creating music. Neural networks, on the other hand, are commonly used for tasks where describing the decision making process is not possible because of its complexity.

The network learns to give “intelligent” responses through a training process: it receives many examples of input, has its performance evaluated on each, and then is given feedback so it can improve over time.įor a long time most AI systems required the programmer to precisely describe how to perform a task to the computer. signals from the nervous system) and produce an appropriate output (e.g.

Similar to how groups of neurons work, they take an input (e.g. Neural Networks are AI systems inspired by biological brains. We can say that through this training it learned on its own, and by example, what piano music should sound like. Its AI is based on a neural network that was trained with 1400 performances from the International Piano e-Competition. Piano Genie was programmed without coding in any theoretical rules about harmony or composition. The Piano Genie AI will assist you by choosing which piano keys to play to make you sound more like a professional player. When playing you decide the timing of the notes and have some control over the “shape” of the melody: whether it should move up or down in pitch, and by how much.
