This research proposes a method to separate polyphonic music signal into signals of each musical instrument by NMF: Non-negative Matrix Factorization based on preservation of spectrum envelope.
We propose a melody generation system based on the Implication-Realization Model (IRM) of music theory. The IRM is a music theory, which was proposed by Eugene Narmour. The IRM abstracts music. It then expresses music according to symbol sequences based… (READ MORE)
Our goal is to construct an automatic musical arrangement system by applying analysis results of composers’ arrangement processes. We arranged an orchestral score for a solo pianist to evaluate our system. Usually, an orchestral score has several instrumental parts, which… (READ MORE)
We describe the technique for automatically constructing the network which indicates the relationship between bands and musicians from the Web pages. And we also present the applications of the network for the recommendation and the classification of bands. The relation… (READ MORE)
This paper describes a jam session system that enables a human player to interplay with virtual players which can imitate the player personality models of various human players. Previous systems have parameters that allow some alteration in the way virtual… (READ MORE)
Fingering Simulator optimizes guitar fingering of monophony by using physical simulator called Springhead2. Unlike most previous guitar fingering optimization systems focusing on moving distances, our method deals with the torque of the finger joints. Experimental results showed that the maximum… (READ MORE)
This paper describes the Sound Scope Headphones which enable the user to control an audio mixer through natural movements of the head and hands. This allows musical novices to interact closely with the music they listen to. Commercial audio mixers… (READ MORE)
This paper describes a novel audio only interface for selecting music which enables us to select songs without having to click a mouse. Using previous music players with normal headphones, we can hear only one song at a time and… (READ MORE)
The ShakeGuitar is an interactive music system for use with iPhone / iPod touch that enables users to enjoy the simulated experience of guitar playing, even if they are musical novices. Shaking the iPhone / iPod touch with varying degrees… (READ MORE)
