Digital and Handcrafting Processes Applied to Sound-Studies of Archaeological Bone Flutes
2016
Bone flutes make use of a naturally hollow raw-material. As nature does not produce duplicates, each bone has its own inner cavity, and thus its own sound-potential. This morphological variation implies acoustical specificities, thus making it impossible to handcraft a true and exact sound-replica in another bone. This phenomenon has been observed in a handcrafting context and has led us to conduct two series of experiments (the first-one using handcrafting process, the second-one using 3D process) in order to investigate its exact influence on acoustics as well as on sound-interpretation based on replicas. The comparison of the results has shed light upon epistemological and methodological…
Quine’s Fluted Fragment is Non-elementary
2016
We study the fluted fragment, a decidable fragment of first-order logic with an unbounded number of variables, originally identified by W.V. Quine. We show that the satisfiability problem for this fragment has non-elementary complexity, thus refuting an earlier published claim by W.C. Purdy that it is in NExpTime. More precisely, we consider, for all m greater than 1, the intersectionof the fluted fragment and the m-variable fragment of first-order logic. We show that this subfragment forces (m/2)-tuply exponentially large models, and that its satisfiability problem is (m/2)-NExpTime-hard. We round off by using a corrected version of Purdy’s construction to show that the m-variable fluted f…
Individuality of movements in music--finger and body movements during playing of the flute.
2013
The achievement of mastery in playing a composition by means of a musical instrument typically requires numerous repetitions and corrections according to the keys and notations of the music piece. Nevertheless, differences in the interpretation of the same music piece by highly skilled musicians seem to be recognizable. The present study investigated differences within and between skilled flute players in their finger and body movements playing the same piece several times on the same and on different days. Six semiprofessional and four professional musicians played an excerpt of Mozart’s Flute Concerto No. 2 several times on three different days. Finger and body movements were recorded by …
Diseño y validación de un cuestionario para conocer la praxis docente del profesorado de flauta travesera en centros superiores de la comunidad valen…
2017
El objetivo del presente estudio es diseñar y validar un cuestionario para conocer la opinión del profesorado de las enseñanzas superiores de flauta travesera de la Comunidad Valenciana sobre la praxis docente. La población de referencia está formada por el conjunto de profesores de flauta travesera de los tres conservatorios superiores de música de la Comunidad Valenciana: CSM “Oscar Esplà” de Alicante, CSM “Joaquín Rodrigo” de Valencia y CSM “Salvador Seguí” de Castellón. El cuestionario fue enviado a toda la población y la muestra generadora de datos resultó ser del 100%. Sin embargo dos de los encuestados no respondieron, por tanto tenemos un sesgo del 33’33%. Se considera que el estudi…
The fluted fragment with transitive relations
2022
Abstract The fluted fragment is a fragment of first-order logic (without equality) in which, roughly speaking, the order of quantification of variables coincides with the order in which those variables appear as arguments of predicates. It is known that this fragment has the finite model property. We consider extensions of the fluted fragment with various numbers of transitive relations, as well as the equality predicate. In the presence of one transitive relation (together with equality), the finite model property is lost; nevertheless, we show that the satisfiability and finite satisfiability problems for this extension remain decidable. We also show that the corresponding problems in the…
The fluted fragment revisited
2019
AbstractWe study the fluted fragment, a decidable fragment of first-order logic with an unbounded number of variables, motivated by the work of W. V. Quine. We show that the satisfiability problem for this fragment has nonelementary complexity, thus refuting an earlier published claim by W. C. Purdy that it is in NExpTime. More precisely, we consider ${\cal F}{{\cal L}^m}$, the intersection of the fluted fragment and the m-variable fragment of first-order logic, for all $m \ge 1$. We show that, for $m \ge 2$, this subfragment forces $\left\lfloor {m/2} \right\rfloor$-tuply exponentially large models, and that its satisfiability problem is $\left\lfloor {m/2} \right\rfloor$-NExpTime-hard. We…
Fluted Logic with Counting
2021
The fluted fragment is a fragment of first-order logic in which the order of quantification of variables coincides with the order in which those variables appear as arguments of predicates. It is known that the fluted fragment possesses the finite model property. In this paper, we extend the fluted fragment by the addition of counting quantifiers. We show that the resulting logic retains the finite model property, and that the satisfiability problem for its (m+1)-variable sub-fragment is in m-NExpTime for all positive m. We also consider the satisfiability and finite satisfiability problems for the extension of any of these fragments in which the fluting requirement applies only to sub-form…
Influencia de las escuelas flautísticas en la praxis docente del profesorado superior en España
2020
Las escuelas nacionales de flauta travesera han jugado un papel importante en la generalización de las técnicas y en la creación de métodos que han conseguido ser atemporales y de probada solvencia. El objetivo radica en conocer la influencia e influjos que las diferentes escuelas puedan tener sobre el alumnado, y determinar si realmente hoy en día se pueden acotar dichas doctrinas, producto de un momento determinado y en unas circunstancias de expansión del instrumento. Este artículo se centra en datos obtenidos acerca de la influencia que estas escuelas de flauta ejercen sobre el profesorado superior de flauta. Se observa que todos los docentes aplican métodos de autores de distinta escue…
Handcrafting in archaeomusicological research
2016
There were no conference proceedings but you may find video recordings of some of the talks by following the link above; International audience; Archaeological flutes, as sound artefacts, both stand in material and immaterial culture. They are made of tremendous subtleties that archaeologists have a hard time to understand while these are craftsmen's everyday life. These subtleties are the link between material (rough material, tools, gestures) and immaterial (sounds, music, timber, uses) issues. They are the reason why archaeology cannot study ancient sound instruments on its own. A one-year insight experience of apprenticeship alongside a traditional-flute-maker (Jean-Daniel Talma, ElBock…
Mapping the sound world of the flute: towards a new classification of standard and extended techniques
2016
In the last decades, some literature has been published about extended techniques, and composers have made them part of the contemporary music language. However, the classification of extended techniques in these writings is often arbitrary, based on the way they have been discovered and used. In this contribution, a new way of classifying flute playing techniques is proposed, with the aim of grouping them according to their role in sound production and to the gestural parameters that are involved for each of them. First, a definition of the concept of extended technique is given. An overview of publications since the 1960s will show the existing classifications; then types of musical gestu…
