San Jose State University professor Margareta Ackerman has developed the Automated LYrical SongwrIting Application (ALYSIA), an artificial intelligence-based system designed to assist musicians in songwriting.
By feeding ALYSIA lyrics one sentence at a time, the system constructs a predictive model so it can generate multiple melodic suggestions played back on a computerized piano and written out in musical notation. In addition, ALYSIA ranks these melody choices according to what it thinks best, with highly repetitive melodies often penalized.
Ackerman says ALYSIA is unique in its natural-language processing ability, which enables it to learn how words and syllables, and melodies and individual notes, relate to each other.
She envisions such systems as collaborative tools, for both experienced and novice musicians, especially those who practice in the electronic-music genre.
