The rapid development of artificial intelligence, in the future there may be a lot of people are facing unemployment, music is one of them.
Previously, there have been musical AI creation. For example:
US network Taryn Southern red and musician released the song "Break Free", melody and MV are AI creation, Taryn Southern lyrics and singing. According to reports, Taryn Southern enter different variables, such as mood, style, rhythm, and then began to automatically compose the AI. Take a listen:

Sony has publicly over two AI songs

With AI gradually enter the music market, the industry will look very different. Artificial intelligence will soon become a new tool for musicians and composers can not do without the.
In July this year, the Montreal-based start-up company Landr to raise US $ 26 million for his congregation of a product, this product can automatically analyze the style of music, and then create exclusive custom audio processor set to music. Meanwhile OpenAI and Google earlier this year also launched an online authoring tool using the music generation algorithm. 
And inspired by the results of these studies and other work, researchers Sony recently developed a new type of machine learning models for conditional expressions drums path generation. Taking into account existing songs and songs encoded and low-dimensional relationship between the music generation, this artificial intelligence technology from one song to another song to create a variety of feasible accompaniment of drums and music from the results, At the same time does not consider differences in tempo and time changes (that is, change the speed and duration).
"We propose a new model of architecture, it can encode rhythmic interaction between drums and bass patterns. Each mapping code to capture the relationship between the different drums, so that the entire trajectory on a series of related mapping code Union. it is not directly control the generation of rhythm characteristics, but to control the rhythm of the relationship between the generation and regulation. " 
in order to train people this artificial intelligence system, the researchers compiled a set of 665 pop, rock and electronic songs composed data sets, which were played at 44.1 kHz audio between rhythm bass, kick drum and snare drum. The context signal is input mapping comprises two, respectively, and the possibility remake beat and the start of the main functions of the drums and bass. Next, they are placed by all the peak amplitude in the threshold of remaining a simple rhythm to present a group of audio files, so that researchers can be introduced dynamically by selecting the volume of the sample, from the 70% peak threshold to 100% of the maximum peak.
In a series of experiments, researchers use of artificial intelligence system generates conditional transfer drum rhythm pattern and style, or inferred from the application of a song rhythm charts, summarized in a pattern similar to another song. Moreover, they were 80% of the original tempo, 90%, 110% and 120% of the time to create a stretched version of the song, and determining a mapping code. 
The research team also pointed out to rebuild this structure is not perfect, in part because the model "invariance." But the researchers point out, to verify the accuracy and set training set relatively similar.
"We have shown that the mapping code is mainly speed and fixed on the music of the drums track can generate a given rhythm and bass track by sampling the mapping code by style transfer or, and then infer the mapping code by another song. Future follow-up the same method is applied to the work of the snare drum and bass drum rhythm track. "
In the AI era, music for people who have to make their own creations and attitudes more distinctive, more humane, have living space.
