Creating your own musical pieces is one of the most wonderful ways of enjoying music, but many lack the basic musical skills to do so. Andrew Caosun discusses a neural hidden Markov model (NHMM)—a hybrid of a hidden Markov process and a convolutional neural network algorithm with LSTM. This model takes users’ original musical ideas, automatically modifies the input, and generates musically appropriate melodies as output.
The model is extended to allow users to specify magnitude of revision, duration of music segment to be revised, choice of music genres, popularity of songs, and cocreation of songs in social settings. These extensions enhance user understanding of music knowledge, enrich their experience of self-music learning, and enable social aspects of music making. The model is trained using Columbia’s publicly available Million Songs Dataset.
Andrew also explains how he and his team designed a mobile application with an intuitive, interactive, and graphical user interface that’s suitable for the elderly and young children. Unlike most existing literature focusing on computer music composing itself, their research and application aim to use computers to aid human composition and enrich music education for those without musical training.
