FUGATRA. The missing note, from concert to misstep

[Abstract] The project aims to create a web application to help pianists identify the mistakes they make during the performance of a piece of music. It is targeted at the initial phase of study, when it is crucial to correct errors in order to avoid acquiring them, as they are more difficult to fix afterwards. Users can create their own account, upload their own sheet music and connect their keyboard to the computer so that the application can support them during the learning process.[Resumo] O proxecto pretende crear unha aplicación web para axudar aos pianistas a identificar os erros que cometen durante a execución dunha peza musical. Está dirixido á fase inicial do estudo, cando é crucial corrixir os erros para evitar adquirilos, xa que despois son máis difíciles de rectificar. O usuario poderá crear a súa propia conta, subir as súas partituras y conectar o seu teclado ao ordenador para que a aplicación o apoie durante a aprendizaxe.Traballo fin de grao.

FUGATRA: la nota perdida, del desacierto al concierto

[Resumen]: Fugatra surge en 2020 y se presenta en 2021 como una aplicación web para ayudar a los pianistas a identificar los errores en su interpretación en las primeras fases del estudio de una obra musical. Con el ánimo de facilitar a los músicos el estudio y la experiencia en el escenario, durante este proyecto se ampliará la suite de funcionalidades ofrecida por Fugatra: se agrega la opción de seleccionar un fragmento concreto de la partitura a la hora de estudiar con la aplicación para obtener los errores cometidos en esa parte; se incorpora el reconocimiento de voz en la web para dirigir el paso de hoja de una partitura y se desarrolla una aplicación móvil que ofrece esta misma funcionalidad pero, en vez de con comandos de voz, con dos pulseras Bluetooth; otras utilidades menores también son incluidas.[Abstract]: Fugatra emerged in 2020 and was introduced in 2021 in the form of a web-based application to help pianists identify errors in their playing during the early stages of studying a musical piece. In order to support the musicians’ learning and on-stage experience, the suite of functionalities offered by Fugatra will be extended during this project: the opportunity of selecting a specific fragment of the score when studying with the application in order to obtain the committed mistakes is added; voice recognition is incorporated into the web to manage the page turning of a score and a mobile application is developed to offer the same functionality but, instead of using voice commands, via two Bluetooth wristbands; other minor utilities are also included.Traballo fin de mestrado (UDC.FIC).

Indexing and Retrieval of Scores by Humming based on Extracted Features

Cursos e Congresos, C-155[Abstract] In order to be able to conduct searches over large collections of music scores with queries provided in audio format, this article considers recent literature in the field and proposes an implementation to extract specific features from music pieces. Afterwards, we index those features using modern Lempel-Ziv (LZ)-based data structures. These data structures take advantage of the intrinsic repetitiveness within music to reduce space consumption and, at the same time, to index the information optimizing the search time per query. Furthermore, taking advantage of this property-based representation framework, which does not depend on the way the music is portrayed, we enable the possibility to perform melodic searches by simply providing a query audio. This research branch is known as “query by humming” and has commonly been applied to audio sources. A preliminary study for its application in other forms of music representation is presented in this research.Xunta de Galicia; ED431G 2019/01Xunta de Galicia; ED431C 2021/53Work funded by: CITIC is funded by the Xunta de Galicia through the collaboration agreement between the Consellería de Cultura, Educación, Formación Profesional e Universidades and the Galician universities for the reinforcement of the research centres of the Galician University System (CIGUS), 80% through FEDER funds, Galicia Operational Programme FEDER 2014-2020, and the remaining 20% by the “Secretaría Xeral de Universidades” (Grant ED431G 2019/01), Xunta de Galicia/FEDERUE [ED431C 2021/53]; Ministry of Science and Innovation [PID2020-114635RBI00; PDC2021-120917-C21; PDC2021-121239-C31; PID2019-105221RB-C41; TED2021- 129245-C21
