Interested in Making Your Own Musical Jams? There's an App for That!
Credit: Computer Science For Fun
Aspiring disk jockeys and musicians will be able to make music using a smartphone app developed by Queen Mary, University of London researchers. The Melody Triangle app enables users to choose from drum, piano, and bass sounds and create an infinite combination of rhythms and melodies. The triangle refers to the interface to artificial intelligence-based software that selects notes for the user, which can be varied by dragging tokens around the screen. Data collected from users will enable scientists to answer questions about musical tastes and aesthetics.
"I'm interested in finding out what it is that makes some music more engaging than others, and one small part of the puzzle has to do with understanding the role of predictability in music," says Queen Mary's Henrik Ekeus. "Do people prefer repetitive musical patterns or do they like to have variety in their music? And if so how much? If it is easy to predict the next note of a melody, does it make the melody boring or satisfying?"
The free app works with Android mobile phones.
