We analyze problems of music searching and main tasks the developers face in the domain of music information retrieval. We introduce the architecture of the software and the data model for integrated access to existing music searching web services. We illustrate our approach by developing a mobile accessed software prototype which allows users of Android running touch screen devices accessing s...

Popular music plays a central role in the lives of millions of people. It motivates beginners, engages experienced musicians, and plays both functional (e.g. churches) and non-functional (e.g. music festivals) roles in many contexts. Forming and maintaining a popular music ensemble can be challenging, particularly for part-time musicians who face other demands on their time. Where an ensemble h...

Music is primarily auditory but also includes visual elements such as: notation or mental images while hearing music. Music television like MTV or the visualization of music by visual jockeys (VJs) are further examples of combining music with images. However, not much is known about the interaction between auditory and visual representation and perception [1]. How can graphic visualizations int...

Developing a theoretical framework for electro-acoustic music presents an array of problems not present in the analysis of Western tonal and post-tonal music. We present a theoretical framework characterized by the interaction of a perceptual and an analytic model. The perception of a composition is used to inform the analytic model. The analytic model examines aspects of a composition ranging ...

Important aspects of judging a singing performance include musical accuracy and voice quality. In the context of Indian classical music, not only is the correct sequence of notes important to musical accuracy but also the nature of pitch transitions between notes. These transitions are essentially related to alankars (ornaments) that embellish the inherent beauty of the genre. Thus a higher lev...

Melodic similarity is an important concept for music databases, musicological studies, and interactive music systems. Dynamic programming is commonly used to compare melodies, often with a distance function based on pitch differences measured in semitones. This approach computes an “edit distance” as a measure of melodic dissimilarity. The problem can also be viewed in probabilistic terms: What...

In recent years, there has been an increase in the number of artists who make use of automated music performances in their music and live concerts. Automated music performance is a form of music production using programmed musical notes. Some artists who introduce automated music performance operate parameters of the sound in their performance for production of their music. In this paper, we fo...

In this study, the task of vocal duration estimation in monaural music mixtures is explored. We show how presently available algorithms for source separation and predominant f0 estimation can be used as a front end from which features can be extracted. A large set of features is presented, devised to connect different vocal cues to the presence of vocals. Two main cues are utilized; the voice i...

This paper describes a consumer behavior model for online shopping, especially online music services, because they are the most popular online shopping service in Japan. Based on Howard's consumer decision model, questionnaires about decision making for online music services were given to 282 students. The questionnaire results show that almost 90% of respondents have downloaded from online mus...

 Professional musicians manipulate sound properties such as timing, energy, pitch and timbre in order to add expression to their performances. However, there is little quantitative information about how and in which context this manipulation occurs. This is particularly true in Jazz music where learning to play expressively is mostly acquired intuitively. In this paper we describe a machine le...
