Let's take a look at the machine learning models we are going to train to get our music generation results.
This approach makes sense in the world of music generation as each token in a melody sounds good or not so good depending on the past, current, and following sounds. Transformers and neural networksĪ transformer is an architecture used for neural networks that contains a number of specific layers called attention layers.įor every token in an input melody, the attention layer generates an attention vector that infers the relationship between this token and the other input tokens. With the sequences of input as input vectors, most of the time, the models are trained with the natural language processing ( NLP) task of predicting the next token of a sequence at each time step. With raw audio, most algorithms will use the raw representation of the audio at each timestep. We then use that representation as a natural language to train our models. MIDI files are structured files that provide information ordered on notes, changes in rhythm, BPM (beats per minute), etc. We can use MIDI files (used to save, transport & open music sequences) to train the models we will explore. As a result, here lies our first problem - how can we represent music as numbers? To achieve this, we must think of a melody as a sequence of numeric tokens whereas each token (a vector), has some information about the note, rhythm, and timbre, as well as other characteristics that we can represent. Machine learning models are used as inputs in the shape of numeric vector(s) that represent the input we want to provide the model in an understandable manner.
Machine learning and music representation Want to work with innovative AI technologies? We’re hiring ! What is a deep neural network?Ī deep neural network is a neural network composed by several layers. The difference between a neural network and a deep neural network is that the latter has more than 2 hidden layers and as a result the architecture is more complex. We will walk through some methods that combine different neural networks techniques, as well as introduce and breakdown some of these concepts and how they operate. These machine learning methods can be used by music composers and producers to generate music and act as an assistance tool for their work. The purpose of this article is to look at state-of-the-art methods and deep neural network models behind these models. This innovative area of machine learning has been gathering pace for a number of decades. Similar to AI now being able to generate images, this technology is also capable of generating music through the use of deep learning techniques. Generative art refers to a piece of art, or a certain part of that art, that is generated by an autonomous system (a large network or group of networks under one routing policy). In a moment of bonding before Bumblebee dives headfirst into battle with the Decepticons, he plays the same track for her as a way of displaying how much her kindness has meant to him.The ability to generate and synthesize music in real-time is a key topic in generative art. When she fits the new radio into Bumblebee, the first tape she puts in is Strangeways, which BumbleBee spits out after mere seconds. Charlie, being a teenager of alternative culture in the eighties, is a devout fan of the crooning alt-rock band. Fans who have followed the film's publicity will know of Rick Astley's involvement, as the first trailer 'Rick Roll'd' everyone with Astley's pop hit that's since taken on another life as a popular internet prank.Īnother notable addition is The Smiths' 'Girlfriend In A Coma' form their 1987 album Strangeways, Here We Come. Steinfeld wanted to do a song for her character, and it's the music that plays as we go into the credits of the movie.īumblebee doubles down hard on the nostalgia, featuring the ending of The Breakfast Club in addition to the Simple Minds' synth classic. Hailee, who plays Charlie, has been a rising pop-star in her own right, having released an EP called Haiz in 2015.
There is one track here that's not like the others, and that's Hailee Steinfeld's 'Back to Life'.
