Bach in a Box - Real-Time Harmony
نویسندگان
چکیده
We describe a system for learning J. S. Bach's rules of musical harmony. These rules are learned from examples and are expressed as rule-based neural networks. The rules are then applied in realtime to generate new accompanying harmony for a live performer. Real-time functionality imposes constraints on the learning and harmonizing processes, including limitations on the types of information the system can use as input and the amount of processing the system can perform. We demonstrate algorithms for generating and refining musical rules from examples which meet these constraints. We describe a method for including a priori knowledge into the rules which yields significant performance gains. We then describe techniques for applying these rules to generate new music in real-time. We conclude the paper with an analysis of experimental results.

A harmony search-based approach for real-time volt & var control in distribution network by considering distributed generations units
In recent decade, development of telecommunications infrastructure has led to rapid exchange of data between the distribution network components and the control center in many developed countries. These changes, considering the numerous benefits of the Distributed Generators (DGs), have made more motivations for distribution companies to utilize these kinds of generators more than ever before. ...
متن کاملFuzzy Real-Time Optimization of the Tennessee Eastman Challenge Process
A Real-Time Optimization (RTO) strategy incorporating the fuzzy sets theory is developed, where the problem constraints obtained from process considerations are treated in fuzzy environment. Furthermore, the objective function is penalized by a fuzzified form of the key process constraints. To enable using conventional optimization techniques, the resulting fuzzy optimization problem is the...
متن کاملBach Is the Father of Harmony: Revealed by a 1/f Fluctuation Analysis across Musical Genres
Harmony is a fundamental attribute of music. Close connections exist between music and mathematics since both pursue harmony and unity. In music, the consonance of notes played simultaneously partly determines our perception of harmony; associates with aesthetic responses; and influences the emotion expression. The consonance could be considered as a window to understand and analyze harmony. He...
متن کاملLearning Tonal Harmony from Bach Chorales
Tonal harmony analysis is an intriguing cognitive skill, combining general domain knowledge with contextual cues. In this work we cast it to a Supervised Sequential Learning problem (SSL), and introduce the system geraint, showing how such a problem can be solved via the HMPerceptron algorithm. We explain the main concepts used in music analysis, their use within an automatic environment, and p...
