Automatic transcription of traditional Turkish art music recordings: A computational ethnomusicology appraoach

Thesis (Doctoral)--Izmir Institute of Technology, Electronics and Communication Engineering, Izmir, 2012Includes bibliographical references (leaves: 96-109)Text in English; Abstract: Turkish and Englishxi, 131 leavesMusic Information Retrieval (MIR) is a recent research field, as an outcome of the revolutionary change in the distribution of, and access to the music recordings. Although MIR research already covers a wide range of applications, MIR methods are primarily developed for western music. Since the most important dimensions of music are fundamentally different in western and non-western musics, developing MIR methods for non-western musics is a challenging task. On the other hand, the discipline of ethnomusicology supplies some useful insights for the computational studies on nonwestern musics. Therefore, this thesis overcomes this challenging task within the framework of computational ethnomusicology, a new emerging interdisciplinary research domain. As a result, the main contribution of this study is the development of an automatic transcription system for traditional Turkish art music (Turkish music) for the first time in the literature. In order to develop such system for Turkish music, several subjects are also studied for the first time in the literature which constitute other contributions of the thesis: Automatic music transcription problem is considered from the perspective of ethnomusicology, an automatic makam recognition system is developed and the scale theory of Turkish music is evaluated computationally for nine makamlar in order to understand whether it can be used for makam detection. Furthermore, there is a wide geographical region such as Middle-East, North Africa and Asia sharing similarities with Turkish music. Therefore our study would also provide more relevant techniques and methods than the MIR literature for the study of these non-western musics

Historical sources of ethnomusicology in contemporary debate

This anthology concerns traditional music and archives, and discusses their relationship as seen from historical and epistemological perspectives. Music recordings on wax cylinders, 78 records or magnetic tape, made in the first half of the 20th century, are regarded today as valuable sources for understanding musical processes in their social dimension and as unique cultural heritage. Most of these historical sound recordings are preserved in sound archives, now increasingly accessible in digital formats. Written by renowned experts, the articles here focus on archives, individual and collective memory, and heritage as today’s recreation of the past. Contributors discuss the role of historical sources of traditional music in contemporary research based on examples from music cultures in West Africa, Scandinavia, Turkey, and Portugal, among others. The book will appeal to musicologists and cultural anthropologists, as well as historians and sociologists, and will be of interest to anyone concerned with sound archives, libraries, universities and cultural institutions dedicated to traditional music

A computational study on outliers in world music

The comparative analysis of world music cultures has been the focus of several ethnomusicological studies in the last century. With the advances of Music Information Retrieval and the increased accessibility of sound archives, large-scale analysis of world music with computational tools is today feasible. We investigate music similarity in a corpus of 8200 recordings of folk and traditional music from 137 countries around the world. In particular, we aim to identify music recordings that are most distinct compared to the rest of our corpus. We refer to these recordings as ‘outliers’. We use signal processing tools to extract music information from audio recordings, data mining to quantify similarity and detect outliers, and spatial statistics to account for geographical correlation. Our findings suggest that Botswana is the country with the most distinct recordings in the corpus and China is the country with the most distinct recordings when considering spatial correlation. Our analysis includes a comparison of musical attributes and styles that contribute to the ‘uniqueness’ of the music of each country

From Music Ontology Towards Ethno-Music-Ontology

This paper presents exploratory work investigating the suitability of the Music Ontology - the most widely used formal specification of the music domain - for modelling non-Western musical traditions. Four contrasting case studies from a variety of musical cultures are analysed: Dutch folk song research, reconstructive performance of rural Russian traditions, contemporary performance and composition of Persian classical music, and recreational use of a personal world music collection. We propose semantic models describing the respective do- mains and examine the applications of the Music Ontology for these case studies: which concepts can be successfully reused, where they need adjustments, and which parts of the reality in these case studies are not covered by the Mu- sic Ontology. The variety of traditions, contexts and modelling goals covered by our case studies sheds light on the generality of the Music Ontology and on the limits of generalisation “for all musics” that could be aspired for on the Semantic Web

Computational Analysis of Microtiming in Maracatu De Baque Solto

UIDB/00472/2020 UIDP/00472/2020"Maracatu de baque solto" is a Carnival performance combining music, poetry, and dance, occurring in the Zona da Mata Norte region of Pernambuco (Northeast Brazil). Maracatu percussive music is strongly repetitive, and is played as loud and as fast as possible. Both from an MIR and ethnomusicological perspective this makes a complex musical scene to analyse and interpret. In this paper we focus on the extraction of microtiming profiles towards the longer term goal of understanding how rhythmic performance in Maracatu is used to promote health and well-being. To conduct this analysis we use a set of recordings acquired with contact microphones which minimise the interference between performers. Our analysis reveals that the microtiming profiles differ substantially from those observed in more widely studied South American music. In particular, we highlight the presence of dynamic microtiming profiles as well as the importance of the choice of time-keeper instrument, which dictates how the performances can be understood. Throughout this work, we emphasize the importance of a multidisciplinary approach in which MIR, audio engineering, and ethnomusicology must interact to provide meaningful insight about this music.publishersversionpublishe
