In this paper, we present intermediate results of continuing research into the utility of generalised hierarchical structures for the representation of musical information. We build on an abstract data type presented in Wigginset al. (1989), usingconstituents, which are structurally significant groupings of musical events. We suggest that a division into such groupings can be musically meaningful, and that it can be more flexible than similar approaches. We demonstrate our representation system at work in both analysis and composition, with output from computer programs. We conclude that it is possible and useful to represent music in a way independent of the particular style, tonal system, etc., of the music itself.The authors work in the Department of Artificial Intelligence, University of Edinburgh, Scotland. 相似文献

This paper aims at constructing a music composition system that composes music by the interaction between human and a computer.
Even users without special musical knowledge can compose 16-bar musical works with one melody part and some backing parts
using this system. The interactive Genetic Algorithm is introduced to music composition so that users’ feeling toward music
is reflected in the composed music. One chromosome corresponds to 4-bar musical work information. Users participate in music
composition by evaluating composed works after GA operators such as crossover, mutation, virus infection are applied to chromosomes
based on the evaluation results. From the experimental results, it is found that the users’ evaluation values become high
over the progress of generations. That is, the system can compose 16-bar musical works reflecting users’ feeling.

Algorithmic composition of musical pieces is one of the most popular areas of computer aided music research. Various attempts have been made successfully in the area of music composition. Artificial intelligence methods have been extensively applied in this area. Representation of musical pieces in a computer-understandable form plays an important role in computer aided music research.This paper presents a neural network-based knowledge representation schema for representing notes, melodies, and time in first species counterpoint pieces. A musical note is composed of pitch and duration in this representation schema. The proposed representation technique was tested using the back-propagation algorithm to generate two-voice counterpoint pieces. 相似文献

Despite one and a half decade of research and an impressive body of knowledge on how to represent and process musical audio signals, the discipline of Music Information Retrieval still does not enjoy broad recognition outside of computer science. In music cognition and neuroscience in particular, where MIR’s contribution could be most needed, MIR technologies are scarcely ever utilized—when they’re not simply brushed aside as irrelevant. This, we contend here, is the result of a series of misunderstandings between the two fields, about deeply different methodologies and assumptions that are not often made explicit. A collaboration between a MIR researcher and a music psychologist, this article attempts to clarify some of these assumptions, and offers some suggestions on how to adapt some of MIR’s most emblematic signal processing paradigms, evaluation procedures and application scenarios to the new challenges brought forth by the natural sciences of music. 相似文献

As music can be represented symbolically, most of the existing methods extend some string matching algorithms to retrieve musical patterns in a music database. However, not all retrieved patterns are perceptually significant because some of them are, in fact, inaudible. Music is perceived in groupings of musical notes called streams. The process of grouping musical notes into streams is called stream segregation. Stream-crossing musical patterns are perceptually insignificant and should be pruned from the retrieval results. This can be done if all musical notes in a music database are segregated into streams and musical patterns are retrieved from the streams. Findings in auditory psychology are utilized in this paper, in which stream segregation is modelled as a clustering process and an adapted single-link clustering algorithm is proposed. Supported by experiments on real music data, streams are identified by the proposed algorithm with considerable accuracy.

The use of Information and Communication Technologies (ICT) for students with special learning needs is being particularly studied by the research community. Likewise, music has gained recognition through the years in the field of learning disabilities, playing lately a key role in providing a better quality of life to people with special needs. However, there is still a gap on the combination of ICT and music teaching tools. In this work, we present the results of a case study where students with disabilities took a 3-month introductory music course using the multimedia tool called PLAIME (PLAtform for the Integration of handicapped children in Music Education) developed by the same authors. The aims of this work are three-fold: i) to explore the capability of disabled students to acquire musical knowledge using PLAIME, ii) to measure the improvement in their ICT skills, and iii) to observe their behavior along the study. At the end of the program, students showed an advance in their music knowledge and a positive improvement in behavioral development, being able to perfectly manage the computer platform. 相似文献

The system presented here shows the feasibility of modeling the knowledge involved in a complex musical activity by integrating
sub-symbolic and symbolic processes. This research focuses on the question of whether there is any advantage in integrating
a neural network together with a distributed artificial intelligence approach within the music domain. The primary purpose
of our work is to design a model that describes the different aspects a user might be interested in considering when involved
in a musical activity. The approach we suggest in this work enables the musician to encode his knowledge, intuitions, and
aesthetic taste into different modules. The system captures these aspects by computing and applying three distinct functions:
rules, fuzzy concepts, and learning. As a case study, we began experimenting with first species two-part counterpoint melodies.
We have developed a hybrid system composed of a connectionist module and an agent-based module to combine the sub-symbolic
and symbolic levels to achieve this task. The technique presented here to represent musical knowledge constitutes a new approach
for composing polyphonic music.

This paper presents a representation for melodic segment classes and applies it to music data mining. Melody is modeled as
a sequence of segments, each segment being a sequence of notes. These segments are assigned to classes through a knowledge
representation scheme which allows the flexible construction of abstract views of the music surface. The representation is
applied to sequential pattern discovery and to the statistical modeling of musical style.

Current artificial neural network or connectionist models of music cognition embody feature-extraction and feature-weighting principles. This paper reports two experiments which seek evidence for similar processes mediating recognition of short musical compositions by musically trained and untrained listeners. The experiments are cast within a pattern recognition framework based on the vision-audition analogue wherein music is considered an auditory pattern consisting of local and global features. Local features such as inter-note interval, and global features such as melodic contour, are derived from a two-dimensional matrix in which music is represented as a series of frequencies plotted over time.Manipulation of inter-note interval affected accuracy and reaction time measures in a discrimination task, whereas the same variables were affected by manipulation of melodic contour in a classification task. Musical training is thought of as a form of practice in musical pattern recognition and, as predicted, accuracy and reaction time measures of musically trained subjects were significantly better than those of untrained subjects. Given the evidence for feature-extraction and weighting processes in music recognition tasks, two connectionist models are discussed. The first is a single-layer perceptron which has been trained to discriminate between compositions according to inter-note interval. A second network, using the back-propagation algorithm and sequential input of patterns, is also discussed. 相似文献

The design and implementation of Harbin Institute of Technology—Digital Music Library (HIT-DML) is presented in this paper.
Firstly, a novel framework, a music data model, and a query language are proposed as the theoretical foundation of the library.
Secondly, music computing algorithms used in the library for feature extracting and matching are described. In addition, indices
are introduced for both mining themes of music objects and accelerating content-based information retrieval. Finally, experimental
results on the indices and the current development of the library are provided.
HIT-DML is distinguished by the following points. First, it is inherently based on database systems, and combines database
technologies with multimedia technologies seamlessly. Musical data are structurally stored. Second, it has a solid theoretical
foundation, from framework and data model to query language. Last, it can retrieve musical information based on content against
different kinds of musical instruments. The indices used, also power the library. 相似文献

It can be said that the automatic classification of musical genres plays a very important role in the current digital technology world in which the creation, distribution, and enjoyment of musical works have undergone huge changes. As the number of music products increases daily and the music genres are extremely rich, storing, classifying, and searching these works manually becomes difficult, if not impossible. Automatic classification of musical genres will contribute to making this possible. The research presented in this paper proposes an appropriate deep learning model along with an effective data augmentation method to achieve high classification accuracy for music genre classification using Small Free Music Archive (FMA) data set. For Small FMA, it is more efficient to augment the data by generating an echo rather than pitch shifting. The research results show that the DenseNet121 model and data augmentation methods, such as noise addition and echo generation, have a classification accuracy of 98.97% for the Small FMA data set, while this data set lowered the sampling frequency to 16000 Hz. The classification accuracy of this study outperforms that of the majority of the previous results on the same Small FMA data set. 相似文献

Music is the language of emotions. In recent years, music emotion recognition has attracted widespread attention in the academic and industrial community since it can be widely used in fields like recommendation systems, automatic music composing, psychotherapy, music visualization, and so on. Especially with the rapid development of artificial intelligence, deep learning-based music emotion recognition is gradually becoming mainstream. This paper gives a detailed survey of music emotion recognition. Starting with some preliminary knowledge of music emotion recognition, this paper first introduces some commonly used evaluation metrics. Then a three-part research framework is put forward. Based on this three-part research framework, the knowledge and algorithms involved in each part are introduced with detailed analysis, including some commonly used datasets, emotion models, feature extraction, and emotion recognition algorithms. After that, the challenging problems and development trends of music emotion recognition technology are proposed, and finally, the whole paper is summarized. 相似文献

Digital technology can be used to amplify the wonderful benefits of music. Modern digital technology has great potential to boost music education, especially in very early education. Music drill and practice by computer must always be a background to social musical activity arranged by educators and parents. The great benefit of the computer is that it can impart basic music skill and knowledge that present-day mentors often no longer have because it has faded so much from school and society. 相似文献

A general framework for reasoning about change 总被引:1,自引:0,他引:1
Juan Carlos Augusto 《New Generation Computing》2003,21(3):209-246
The capability to represent and use concepts like time and events in computer science is essential to solve a wide class of
problems characterized by the notion of change. Real-time, databases and multimedia are just a few of several areas which
needs good tools to deal with time. Another area where this concepts are essential is artificial intelligence because an agent
must be able to reason about a dynamic environment.
In this work a formalism is proposed which allows the representation and use of several features that had been recognized
as useful in the attempts to solve such class of problems. A general framework based on a many-sorted logic is proposed centering
our attention in issues such as the representation of time, actions, properties, events and causality. The proposal is compared
with related work from the temporal logic and artificial intelligence areas. This work complements and enhances previously
related efforts on formalizing temporal concepts with the same purpose.
