description: This paper aims to present an aesthetical approach on the exploitation of the history of the Byzantine Empire and the Byzantine chant of the Orthodox psaltic tradition, which constitute the ‘nationalistic elements’ par excellence, in both operas. As regards the composers, Manolis Kalomiris is now recognized internationally as the founder of the Greek National School of Music and Georgios Sklavos is considered to be among its most distinguished members of the first generation. The methodology of this paper is focused on analyzing the elements of hymnography and modes in the composing techniques that each composer employed, in conjunction with the thematic context of the libretto, in order to create a representative atmosphere of the glorious past and the devotional rite as an endeavor of historicism, a style peculiar to Greek national art. How does the experiential conception of the Byzantine chant balance between a simple decorative element and a creative reshaping material, giving essence in the composition itself?

description: Flavor symmetry has been widely studied for figuring out the masses and mixing angles of standard-model fermions. In this paper we present a framework for handling flavor symmetry breaking where the symmetry breaking is triggered by boundary conditions of scalar fields in extra-dimensional space. The alignment of scalar expectation values is achieved without referring to any details of scalar potential and its minimization procedure. As applications to non-abelian discrete flavor symmetries, illustrative lepton mass models are constructed where the S3 and A4 flavor symmetries are broken down to the directions leading to the tri-bimaximal form of lepton mixing and realistic mass patterns.

description: In spite of the great success of deep learning technologies, training and delivery of a practically serviceable model is still a highly time-consuming process. Furthermore, a resulting model is usually too generic and heavyweight, and hence essentially goes through another expensive model compression phase to fit in a resource-limited device like embedded systems. Inspired by the fact that a machine learning task specifically requested by mobile users is often much simpler than it is supported by a massive generic model, this paper proposes a framework, called Pool of Experts (PoE), that instantly builds a lightweight and task-specific model without any training process. For a realtime model querying service, PoE first extracts a pool of primitive components, called experts, from a well-trained and sufficiently generic network by exploiting a novel conditional knowledge distillation method, and then performs our train-free knowledge consolidation to quickly combine necessary experts into a lightweight network for a target task. Thanks to this train-free property, in our thorough empirical study, PoE can build a fairly accurate yet compact model in a realtime manner, whereas it takes a few minutes per query for the other training methods to achieve a similar level of the accuracy.

description: Urban green and blue spaces (UGBS) have the potential to improve public health and wellbeing, address health inequities, and provide co-benefits for the environment, economy, and society. To achieve these ambitions, researchers should engage with communities, practitioners, and policy makers in a virtuous circle of research, policy, implementation, and active citizenship using the principles of co-design, co-implementation, co-evaluation, and cotranslation. This Viewpoint provides an integrated perspective on the challenges that hinder the delivery of healthenhancing UGBS and recommendations to address them. Our recommendations include: strengthening the evidence beyond cross-sectional research designs, strengthening the evidence base on UGBS intervention approaches, evaluating the effects on diverse population groups and communities, addressing inequities in the distribution and quality of UGBS, accelerating research on blue space, providing evidence for environmental effects, incorporating co-design approaches, developing innovative modelling methods, fostering whole-system evidence, harnessing political drivers, creating collaborations for sustainable UGBS action, and advancing evidence in low-income and middle-income countries. The full potential of UGBS as public health, social, economic, and environmental assets is yet to be realised. Acting on the research and translation recommendations will aid in addressing these challenges in collaboration with research, policy, practice, and communities.
Some Piano Improvisations by Nicolas Economou

Subjects: Piano, composer, jazz, improvisations, Cyprus

description: The paper examines some of the piano improvisations of the Cypriot pianist and composer Nicolas Economou (1953-1993). Highly acclaimed for his piano interpretations, Economou is little known as a composer and improviser. A large part of his compositions existed only as recordings and they were notated after his tragic death. The paper reviews how the composer’s creative personality was influenced by the jazz instrumental culture of the 20th century. The research focuses not only on some of the individual improvisations of Economou but also on the “group” improvisations of Nicolas Economou, Friedrich and Paul Gulda, Chick Corea and Rodion Shchedrin during the Munich Summer Piano Festival in 1982 and 1983. Nicolas Economou explained in the preface of the album “On two pianos” that his attempt was to “break down the stuffy ritual surrounding classical music” and bring the spontaneity of music creativity back to the audience. The aims and the objectives of the research are to introduce a very important feature of the creative thinking of Economou – his mastership in improvisation, which is reflected in the different approaches towards the form of his compositions. His great improvisatory talent places him among the most important Cypriot composers.

description: Cosmic voids are underdense regions filling up most of the volume in the Universe. They are expected to emerge in regions comprising negative initial density fluctuations, and subsequently expand as the matter around them collapses and forms walls, filaments and clusters. We report results from the analysis of a cosmological simulation specially designed to accurately describe low-density regions, such as cosmic voids. Contrary to the common expectation, we find that voids also experience significant mass inflows over cosmic history. On average, $10\%$ of the mass of voids in the sample at $z \sim 0$ is accreted from overdense regions, reaching values beyond $35\%$ for a significant fraction of voids. More than half of the mass entering the voids lingers on periods of time $\sim 10 \, \mathrm{Gyr}$ well inside them, reaching inner radii. This would imply that part of the gas lying inside voids at a given time proceeds from overdense regions (e.g., clusters or filaments), where it could have been pre-processed, thus challenging the scenario of galaxy formation in voids, and dissenting from the idea of being pristine environments.

description: The onset of a chronic physical health condition (CHC) can highly impact individuals' well‐being and mental health. Social support has been shown to help people rebound after the onset of a CHC. Nonetheless, little is known about the longitudinal pattern of social support and its reciprocal association with mental health in CHC. This study aimed to illustrate the longitudinal pattern of perceived social support and to examine the reciprocal association between perceived social support and psychological distress across 6 years. Two random intercept cross‐lagged panel models were conducted, one for emotional and one for practical support, using yearly assessments of 582 Swiss Household Panel's participants reporting a CHC. A reciprocal association was found, with psychological distress 1 year after the onset being linked to less emotional support in the following year and vice versa, more emotional support being linked to less psychological distress the following year. A unidirectional association was found for practical support, with more psychological distress 1 year before the CHC onset being linked to more practical support at the onset year. This study underlines the importance of involving the social environment of individuals living with a CHC, especially around the first year after the onset.
Metastable supersymmetry breaking vacua from conformal dynamics

description: We study the scenario that conformal dynamics leads to metastable supersymmetry breaking vacua. At a high energy scale, the superpotential is not R-symmetric, and has a supersymmetric minimum. However, conformal dynamics suppresses several operators along renormalization group flow toward the infrared fixed point. Then we can find an approximately R-symmetric superpotential, which has a metastable supersymmetry breaking vacuum, and the supersymmetric vacuum moves far away from the metastable supersymmetry breaking vacuum. We show a 4D simple model. Furthermore, we can construct 5D models with the same behavior, because of the AdS/CFT dual.

Musical Interpretations of Medea’s Myth in the 21st Century

Year: 2021
Subjects: French opera, ancient Greek tragedy, Medea, myth, 21st century, modality

description: During the first decade of the 2000s, Medea’s myth was revived numerous times on the operatic stage. Among several scenic works, we chose to refer to three French operas which, despite their differences, share some common features: Médée de Thessalonique by Christophe Looten (2001), Médée by Michèle Reverdy (2003) and Medea by Pascal Dusapin (2007), a choreographed version of the composer’s opera Medeamaterial (originally written in 1992) by Sasha Waltz. These operas display a contemporary musical expression and they also reveal very different and modern versions of Medea’s myth, associated to actual events, political or not. Each composer’s point of view, their goals and choices concerning the myth’s adaptation, vocal treatment, instrumentation and musical language show not only how intriguing is to represent Medea’s character for an artist, but also how an ancient female archetype can offer countless possibilities for ingenious and powerful operas. As a free and strong immigrant woman, Medea is reflected in a way in the face of modern women, who still fight to find their place in patriarchal societies. As a result, Medea’s myth is present in musical creation of our days and largely contributes to the fact that ancient Greek drama remains an indelible source of inspiration for the French contemporary opera.

Octaechia and Melismaticity in Byzantine Music. Collations and Musicological Reductive – Statistical Analysis

Subjects: melismaticity, octaechia, longest kekragaria (Megista), palaeographical musicological and statistical analysis

description: Two characteristic elements of the Byzantine melos are the Octaechia (the system of the eight modes) and the melismatic texture of many pieces of its vast repertory. Through the 20th century and until today, attention has been drawn in Byzantine Musicology to the importance of comparative studies between the Middle- 43 and New-Byzantine notations, while taking in mind the so-called theseis and the oral tradition. In this study we examine the so-called Greatest Kekragaria ascribed to St. John of Damascus in the eight modes, through a comparative study of manuscripts in the old notation (14th-18th cent.) and in the new notation from the exegesis (musical interpretation) of the Three Teachers (19th cent.). A detailed multi-perspectival musicological analysis is applied to the material, including reductive analysis of the Kekragaria on both micro-, medial- and macrostructural level. The findings of this study reveal: a) structural and perceptual mechanisms of the old notation in its different evolutionary levels, b) the modality as it is stenographically embodied in the old notation, c) some elements of the technique of the exegesis and d) the relation between melismatic texture and octaechia because any change of the melismatic texture influences the idioms of the eight modes.

description: The purpose of the presented research is estimation of the performance characteristics of the economic Total-Body Jagiellonian-PET system (TB-J-PET) constructed from plastic scintillators. The characteristics are estimated according to the NEMA NU-2-2018 standards utilizing the GATE package. The simulated detector consists of 24 modules, each built out of 32 plastic scintillator strips (each with cross section of 6 mm times 30 mm and length of 140 cm or 200 cm) arranged in two layers in regular 24-sided polygon circumscribing a circle with the diameter of 78.6 cm. For the TB-J-PET with an axial field-of-view (AFOV) of 200 cm, a spatial resolutions of 3.7 mm (transversal) and 4.9 mm (axial) are achieved. The NECR peak of 630 kcps is expected at 30 kBq/cc activity concentration and the sensitivity at the center amounts to 38 cps/kBq. The SF is estimated to 36.2 %. The values of SF and spatial resolution are comparable to those obtained for the state-of-the-art clinical PET scanners and the first total-body tomographs: uExplorer and PennPET. With respect to the standard PET systems with AFOV in the range from 16 cm to 26 cm, the TB-J-PET is characterized by an increase in NECR approximately by factor of 4 and by the increase of the whole-body sensitivity by factor of 12.6 to 38. The TOF resolution for the TB-J-PET is expected to be at the level of CRT=240 ps (FWHM). For the TB-J-PET with an axial field-of-view (AFOV) of 140 cm, an image quality of the reconstructed images of a NEMA IEC phantom was presented with a contrast recovery coefficient (CRC) and a background variability parameters. The increase of the whole-body sensitivity and NECR estimated for the TB-J-PET with respect to current commercial PET systems makes the TB-J-PET a promising cost-effective solution for the broad clinical applications of total-body PET scanners.

The Byzantine Modal System in Relation to Ancient Greek Music Theory

description: Theoretical treatises on church-music appear for the first time in the 14th/ 15th centuries. This seems rather late in comparison with the notated music-manuscripts which were already handed down since at least the 10th century. Only the so-called Hagiopolites goes back at least to the 12th century. Common intent of the theoretical treatises was above all to give practical orders to singers and composers. But on the other side the authors try to show, that Byzantine music has a connection with the ancient modal system. There are many hints in the Byzantine treatises, that the modal system of the eight echoi is based on the ancient διὰ πασῶν, expressed by the term διπλασμός or διπλοφωνία. It shows the idea of the eight-chorded instrument, which forms the Byzantine tonal system. In the ancient theory the systema teleion, as essence of all systems, comprises two octaves – δὶς διὰ πασῶν. In the Byzantine treatises the ancient tonoi dorios, lydios, phrygios, mixolydios and their hypotonoi are set in comparison with the Byzantine echoi. Gabriel Hieromonachos states that 15 notational signs can express dýo diplasmoí. First hints to the Byzantine modal system are found in papyri from the 6th and 7th century, shown by martyriai. If there was already an intonation formula is uncertain. But in the middle of the 9th century, the latin theorist Aurelian of Réome speaks about the Byzantine intonation formulas as laetantis adverbia. In few Sticheraria of the 11th/12th c. in Coislin notation we find an extensive system of intonation formulas, which was reduced to one or two formulas in diastematic middle-byzantine notation. In palaeobyzantine notation, phthorai, hemiphthorai and mesos-signs are found, which disappear completely in the first stages of middle-byzantine notation. The question is: Are there any relations to the ancient Greek tonal system? How was the formation of martyriai and intonation formulas? How were the phthorai and hemiphthorai used in paleobyzantine notation and why did they disappear at the beginning of the diastematic middle-byzantine notation?

description: We obtained spectra of some 140 globular clusters (GCs) associated with the Virgo central cD galaxy M87 with the Subaru/FOCAS MOS mode. The fundamental properties of GCs such as age, metallicity and $α$-element abundance are investigated by using simple stellar population models. It is confirmed that the majority of M87 GCs are as old as, more metal-rich than, and more enhanced in $α$-elements than the Milky Way GCs. Our high-quality, homogeneous dataset enables us to test the theoretical prediction of inflected color$-$metallicity relations (CMRs). The nonlinear-CMR hypothesis entails an alternative explanation for the widely observed GC color bimodality, in which even a unimodal metallicity spread yields a bimodal color distribution by virtue of nonlinear metallicity-to-color conversion. The newly derived CMRs of old, high-signal-to-noise-ratio GCs in M87 (the $V-I$ CMR of 83 GCs and the $M-T2$ CMR of 78 GCs) corroborate the presence of the significant inflection. Furthermore, from a combined catalog with the previous study on M87 GC spectroscopy, we find that a total of 185 old GCs exhibit a broad, unimodal metallicity distribution. The results corroborate the nonlinear-CMR interpretation of the GC color bimodality, shedding further light on theories of galaxy formation.

description: The equation which governs the temporal evolution of a gravitational wave (GW) in curved space-time can be treated as the Schrodinger equation for a particle moving in the presence of an effective potential. When GWs propagate in an expanding Universe with constant effective potential, there is a critical value (k_c) of the comoving wave-number which discriminates the metric perturbations into oscillating (k > k_c) and non-oscillating (k < k_c) modes. As a consequence, if the non-oscillatory modes are outside the horizon they do not freeze out. The effective potential is reduced to a non-vanishing constant in a cosmological model which is driven by a two-component fluid, consisting of radiation (dominant) and cosmic strings (sub-dominant). It is known that the cosmological evolution gradually results in the scaling of a cosmic-string network and, therefore, after some time (\Dl \ta) the Universe becomes radiation-dominated. The evolution of the non-oscillatory GW modes during \Dl \ta (while they were outside the horizon), results in the distortion of the GW power spectrum from what it is anticipated in a pure radiation-model, at present-time frequencies in the range 10^{-16} Hz < f < 10^5 Hz.

New Method of Byzantine Music (BM) Intervals' Measuring and Its Application in the Fourth Mode. Α New Approach of the Music Intervals’ Definition
Creators: name: Delviniotis, Dimitrios S.
Publisher: name: Series Musicologica Balcanica
Year: 2021
Subjects: Pitch analysis, Byzantine Chant, music interval

description: In the last few years various musicological studies on the Byzantine Chant (BC) have been made via computer analysis. Due to the BC vocal nature and the pitch variability of the BC notes during the performance, the value of a music interval between two such notes in a certain BC mode - “echos”, is ambiguous. Because of that pitch variability a new method of BC intervals measurement is proposed, based on statistical processing of the pitch track that can be done after a proper pitch analysis of the BC recordings. The music scale of a particular BC echos is computed from the histogram of the pitch values by applying an algorithm that calculates a Gaussian Mixture Model approximating the music scale of that BC echos. This new method is applied, as an example, to ten BC recordings - performances of the Cherubic Hymn composed in the fourth echos ("aghia") by Petros Lampadarios. The recordings come from the DAMASKINOS Corpus of University of Athens and the analysis results are in agreement with both the theoretical values of the Patriarchal Committee 1881 (approximation of up to 1 moria) and the findings in other similar studies. This method of analysis can be a base for both musicological analysis and music signal processing.

description: We study the influence of pentagons, dislocations and other topological defects breaking the sublattice symmetry on the magnetic properties of a graphene lattice in a Hartree Fock mean field scheme. The ground state of the system with a number of vacancies or similar defects belonging to the same sublattice is known to have total spin equal to the number of uncoordinated atoms in the lattice for any value of the Coulomb repulsion U according to the Lieb theorem. We show that the presence of a single pentagonal ring in a large lattice is enough to alter this behavior and a critical value of U is needed to get the polarized ground state. Glide dislocations made of a pentagon-heptagon pair induce more dramatic changes on the lattice and the critical value of U needed to polarize the ground state depends on the density and on the relative position of the defects. We found a region in parameter space where the polarized and unpolarized ground states coexist.

description: We study the effects of the tidal interaction with the companion, via orbital separation and binary mass ratio, on the global one-armed oscillation modes in disks around binary Be stars. Our model takes into account the three-dimensional effect that contributes to the mode confinement, which was recently found by Ogilvie(2008). We find that the one-armed oscillations are well confined in systems with disks larger than a few tens of stellar radii. In such systems, the oscillation period depends little on the binary parameters. On the other hand, in systems with smaller disks, where the mode confinement is incomplete, the oscillation period increases with increasing orbital separation and/or decreasing binary mass ratio. The eigenmode is insensitive to the spectral type of the central star. Our results suggest that the dependence of V/R oscillation period on the orbital separation and binary mass ratio should be observed only in short period binary systems, and that, for systems with a similar orbital period, those with higher mass ratios will show shorter V/R variations.

description: We study the stability and evolution of various elastic defects in a flat graphene sheet and the electronic properties of the most stable configurations. Two types of dislocations are found to be stable: "glide" dislocations consisting of heptagon-pentagon pairs, and "shuffle" dislocations, an octagon with a dangling bond. Unlike the most studied case of carbon nanotubes, Stone Wales defects are unstable in the planar graphene sheet. Similar defects in which one of the pentagon-heptagon pairs is displaced vertically with respect to the other one are found to be dynamically stable. Shuffle dislocations will give rise to local magnetic moments that can provide an alternative route to magnetism in graphene.

description: The three teachers (Chrysanthos, Gregorios and Chourmouzios) established and taught the New Method of ecclesiastical music (1814-1820) and interpreted an enormous corpus of Byzantine and post-Byzantine compositions to it. However, while studying the psaltic manuscripts we also detect many musical works of well-known composers which hadn’t been transcribed to this analytical musical notation by them, nor by their posteriors. In the paper with the aforementioned title I will present some interesting compositions of this category and I will focus on a specific work of Antonios the priest which I transcribed in the nowadays musical notation.

description: We report a droplet microfluidic method to target and sort individual cells directly from complex microbiome samples, and to prepare these cells for bulk whole genome sequencing without cultivation. We characterize this approach by recovering bacteria spiked into human stool samples at a ratio as low as 1:250 and by successfully enriching endogenous Bacteroides vulgatus to the level required for de-novo assembly of high-quality genomes. While microbiome strains are increasingly demanded for biomedical applications, the vast majority of species and strains are uncultivated and without reference genomes. We address this shortcoming by encapsulating complex microbiome samples directly into microfluidic droplets and amplify a target-specific genomic fragment using a custom molecular TaqMan probe. We separate those positive droplets by droplet sorting, selectively enriching single target strain cells. Finally, we present a protocol to purify the genomic DNA while specifically removing amplicons and cell debris for high-quality genome sequencing.

description: The purpose of this article is to show how the isotropy subgroup of leaf permutations on binary trees can be used to systematically identify tree-informative invariants relevant to models of phylogenetic evolution. In the quartet case, we give an explicit construction of the full set of representations and describe their properties. We apply these results directly to Markov invariants, thereby extending previous theoretical results by systematically identifying linear combinations that vanish for a given quartet. We also note that the theory is fully generalizable to arbitrary trees and is equally applicable to the related case of phylogenetic invariants. All results follow from elementary consideration of the representation theory of finite groups.

description: We present new data obtained with the Submillimeter Array for a sample of fourteen nearby luminous and ultraluminous infrared galaxies. The galaxies were selected to have luminosity distances D < 200 Mpc and far-infrared luminosities log(L_FIR) > 11.4. The galaxies were observed with spatial resolutions of order 1 kpc in the CO J=3-2, CO J=2-1, 13CO J=2-1, and HCO+ J=4-3 lines as well as the continuum at 880 microns and 1.3 mm. We have combined our CO and continuum data to measure an average gas-to-dust mass ratio of 120 +/- 28 (rms deviation 109) in the central regions of these galaxies, very similar to the value of 150 determined for the Milky Way. This similarity is interesting given the more intense heating from the starburst and possibly accretion activity in the luminous infrared galaxies compared to the Milky Way. We find that the peak H_2 surface density correlates with the far-infrared luminosity, which suggests that galaxies with higher gas surface densities inside the central kiloparsec have a higher star formation rate. The lack of a significant correlation between total H_2 mass and far-infrared luminosity in our sample suggests that the increased star formation rate is due to the increased availability of molecular gas as fuel for star formation in the central regions. In contrast to previous analyses by other authors, we do not find a significant correlation between central gas surface density and the star formation efficiency, as trace by the ratio of far-infrared luminosity to nuclear gas mass. Our data show that it is the star formation rate, not the star formation efficiency, that increases with increasing central gas surface density in these galaxies.

Approaching the Texture of the Greek Evangelical Hymnography
Creators: name: Konstantinou, Vasiliki
Publisher: name: Series Musicologica Balcanica
Year: 2021
Subjects: Greek Evangelical Hymnography; Cappadocia; Karamanli Writing

description: This paper explores the Greek Evangelical Hymnography, considering not only the Lutheran protestant tradition but also the way the origins of the churches influenced the hymn melodies. Moreover, it focuses on the presentation and the analysis of evangelical hymns which were mainly sung in Cappadocia. Emphasis is placed on the analysis of three hymns, the melodies of which were only passed down through oral tradition (nowadays almost forgotten), and which are presented for the first time in this paper. Since the population exchange between Greece and Turkey took place at the beginning of the 20th century, two different cultural environments started to coexist amongst the churches that settled in Greece, the Modern Greek and the Ottoman. Each one affected the language of the hymnography and its musical texture (modality, harmony and rhythm).

Modality in Greek Music (1900-50) in Expressing Different Perceptions of the Nation
Creators: name: Chardas, Konstantinos
Publisher: name: Series Musicologica Balcanica
Year: 2021
Subjects: Greece; modality; identity; Romeic; Hellenic

description: A variety of modal collections (from different traditions, or self-invented) entered Greek art music from 1900 to 1950. Since the modal intervallic content inevitably determines the final sound result, these collections and the way they are employed essentially express a wide spectrum of ideological inclinations and nuances, even, within the widely-spread nationalist agenda of the era. Drawing on research from the modern Greek studies, the present chapter proposes to examine modality as expressing and promoting different perceptions of Greek identity: the Romeic (which gives emphasis to the Byzantine past) and the Hellenic (which opts for the ancient Greek heritage). Detailed analysis on specific works discusses how these different perceptions of national identity may be seen to be expressed by modality in the music of two members of the first generation of Greek nationalist composers (Manolis Kalomiris and Petros Petridis) and two of the second generation (Menelaos Pallandios and Yannis A. Papaioannou). The aim of the present research is to open up the critical approach to modality as a vehicle for understanding nuances of the notion of musical nationalism in Greece of the first half of the 20th century, beyond its initial promotion as an homogenous cultural movement.

description: The dynamics of fluctuations is considered for electrons near a positive ion or for charges in a confining trap. The stationary nonuniform equilibrium densities are discussed and contrasted. The linear response function for small perturbations of this nonuniform state is calculated from a linear Markov kinetic theory whose generator for the dynamics is exact in the short time limit. The kinetic equation is solved in terms of an effective mean field single particle dynamics determined by the local density and dynamical screening by a dielectric function for the non-uniform system. The autocorrelation function for the total force on the charges is discussed.

Modality vs. Chordal Harmony: Hybrid Aspects of Rebetiko During the Interwar Period
Creators: name: Delegos, Spiros Th.
Publisher: name: Series Musicologica Balcanica
Year: 2021
Subjects: Rebetiko, Hybridity, Makam, Modality, Chordal Harmony, Interwar period

description: This paper addresses the contribution of modality, chordal harmony and the relationship between them to the formulation of ‘Rebetiko’ –a musical genre of Greek Urban Popular Music– during the interwar period. The aim of the research is to show the hybrid character of Rebetiko through the analysis of the confrontation between the makam modality and an idiosyncratic form of chordal harmony, transcending the typical East-West dipole. After having listened to a large corpus of gramophone recordings of that period, I chose some of the most representative musical pieces –in terms of harmonization and modality– in order, firstly, to document them in transcriptions and, secondly, to analyze and interpret them within their socio-cultural context. The establishment of the equal tempered three-course bouzouki and the censorship by Metaxas’ regime are peculiar forms of modernization and westernization respectively, which contributed to the hybrid aspects of this genre. The interplay between the Greek and the other ethnic communities within the eastern Mediterranean context, the deterritorialization of the musical culture from the broader area of Anatolia to the Greek state due to the Greek refugee movement (1922-23) are some of the basic factors which facilitate the understanding of the cultural osmosis responsible for this musical syncretism.
