L'evolució dels estudis per a piano : del taller al gran repertori de concert

Aquest projecte final proposa un recorregut per l'evolució dels estudis per a piano des de la segona meitat del segle XVIII fins a l'inici del segle XX. El treball està format per tres capítols de recerca històrica i un d'anàlisi de les obres del recital que acompanya la part escrita. Aquestes peces han estat analitzades a partir dels coneixements adquirits en la recerca. Per tant, a través del treball escrit es contextualitza i justifica la selecció de les obres del concert.

Voice Transformations for Extreme Vocal Effects

Extreme Vocal Effects (EVE) in music are so recent that few studies have been carried out about how they are physiologically produced and whether they are harmful or not for the human voice.Voice Transformations in real-time are possible nowadays thanks to new technologies and voice processing algorithms. This Master's Thesis pretends to define and classify these new singing techniques and to create a mapping between the physiological aspect of each EVE to its relative spectrumvariations.Voice Transformation Models based on these mappings are proposed and discussed for each one of these EVEs. We also discuss different transformation methods and strategies in order to obtain better results.A subjective evaluation of the results of the transformations is also presented and discussed along with further work, improvements, and working lines on this field.

Osteolytic metastasis detected by F18-FDG PET in a patient with lung carcinoma

We present a 53-year-old man with a vocal cord paralysis observed as a primary manifestation of lung carcinoma. Tc-99m MDP whole body bone scan were performed and resulted a normal scintiscan. The bone scan does not revealed suspicious foci of uptake. The possibility of bone metastasis was taken into consideration. A whole body F18-FDG-PET scan showed intense uptake in the left upper lung corresponding to the primary tumor. A bronchial biopsy confirmed infiltration by small cell lung carcinoma (SCLC). SCLC is composed of poorly differentiated, rapidly growing cells with disease usually occurring centrally rather than peripherally. It metastasizes early. The whole-body F18-FDG-PET scan clearly demonstrated a focus of increased uptake in the second lumbar vertebral body suspicious for osteolytic metastasis. A lytic bone metastasis was confirmed by MRI. The patient then received therapy and underwent follow up abdominal CT. The scan showed blastic changes in the L2 vertebra suggesting response to treatment.

Correlations between Vocal Input and Visual Response Apparently Enhance Presence in a Virtual Environment

This work investigates novel alternative means of interaction in a virtual environment (VE).We analyze whether humans can remap established body functions to learn to interact with digital information in an environment that is cross-sensory by nature and uses vocal utterances in order to influence (abstract) virtual objects. We thus establish a correlation among learning, control of the interface, and the perceived sense of presence in the VE. The application enables intuitive interaction by mapping actions (the prosodic aspects of the human voice) to a certain response (i.e., visualization). A series of single-user and multiuser studies shows that users can gain control of the intuitive interface and learn to adapt to new and previously unseen tasks in VEs. Despite the abstract nature of the presented environment, presence scores were generally very high.

"Quería crear un nuevo cosmos" : Aleksandr Scriabin y su sonata para piano nº 9

A partir de l’estudi general de l’obra d’Aleksandr Scriabin i a partir de l’anàlisi particular de la Sonata núm. 9 així com de les distintes influències que va tenir, el treball pretén fer una valoració de com caldria interpretar la Sonata núm. 9. És per això que hom fa una introducció general a la vida de Scriabin i el situa en el seu context històric; estudia el seu interès per la filosofia i com aquesta va influir en la seva obra. Alhora hom analitza la faceta de Scriabin com a pianista i en revisa l’obra com a compositor. La segona part del treball, pròpiament analítica, entra en la qüestió de les sonates i la importància que adquireixen en tota la seva obra per tal de centrar-se, en el darrer punt, en la Sonata núm. 9 i l’enfocament interpretatiu que podria tenir. Aquí, a partir del que prèviament s’ha estudiat, hom proposa una possibilitat interpretativa. En relació a aquest punt es comparen interpretacions de diversos pianistes.

El piano francès dels segles XX i XXI : una breu investigació per al disseny d'un repertori de concert

Aquest projecte pretén estudiar les aportacions de Messiaen, Dutilleux i Boulez en l’escriptura pianística, analitzant-ne la transcendència en el terreny interpretatiu actual. Per tal d’assolir aquest objectiu, es repassa quina ha sigut l’evolució de la tècnica pianística francesa, s’estudia el material i les circumstàncies que originen els respectius catàlegs per a piano i es realitza una comparativa del repertori estudiat en els principals conservatoris superiors de Barcelona, París, Sant Petersburg i Moscou. Aquest anàlisi permet determinar que el conservatori de París potencia les obres de nova creació, mentre que als de Barcelona, Sant Petersburg i Moscou encara s’opta per un estudi convergent al cànon. Com a conseqüència, els autors esmentats es consideren objecte d’estudi essencial a París, mentre que a Barcelona i les urbs russes encara no s’han establert en el pla d’estudis.
