description: Citizen science, which involves engaging the general public in research tasks, is increasingly used in animal behaviour studies. In this review we conducted a SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) to evaluate two methodologies of data collection using citizen science in order to study cat-cat interactions: online survey responses and caregiver-recorded home videos analysed by researcher(s). Using the SWOT-analysis on both methodologies, we listed intrinsic aspects that facilitate (Strengths) or interfere with (Weaknesses) reaching scientific goals, as well as the features that the methodology may be able to capitalise on (Opportunities) or which limit its value (Threats). A major strength of online surveys is the possibility to access caregivers’ specific knowledge of their cats, while sampling bias often is a potential weakness. Opportunities of surveys are the methodology´s flexibility and data collection efficiency, but at the same time suffering from threats related to biases associated with caregiver interpretation of their pet’s behaviour. Strengths of caregiver-recorded videos capturing cats’ behaviour include that they allow expert behavioural observations and scoring in a systematic manner (e.g. using an ethogram) and thus yielding quantitative data (whose reliability can be tested between and within observers). Furthermore, given the ubiquity of smartphones, filming cats is not a burden for most caregivers, and the collected recordings can potentially contain high-quality data that may otherwise be inaccessible, or subject to bias if a researcher had been present in the home environment. Though, caregivers’ influence on and lack of standardisation of the recordings are weaknesses which possibly influence the quality of the collected data. Opportunities include public engagement with science, while possible Threats may be related to privacy of the caregivers participating. In this review we consider in more detail each of the four SWOT components related to each methodology in order to optimise cat behaviour research in the future. The authors suggest strategies for future studies using the research methodologies discussed in this review and give specific recommendations when using caregiver-recorded videos in behavioural studies. Additionally, smart combinations of both online surveys with home videos recorded by caregivers might overcome some limitations of the individual methodologies, and would thus be a potentially stronger approach.

Kein Tag vergeht, ohne dass wir von Konflikten zwischen Menschen hören, die schwächeren Formen von Gewalt nehmen wir nur noch am Rande zur Kenntnis. Ist das Gewaltpotential der Erde wirklich gestiegen? Relativ zur gewachsenen Weltbevölkerung, so meinen seriöse Forscher, sei es sogar gesunken. Grund genug, sich dieses Themas einmal aus der Sicht verschiedener Disziplinen im Rahmen des „Studium Generale“ anzunehmen. Aggression taucht in sehr unterschiedlichen Zusammenhängen auf. Das kann die Frage nach dem Einfluss von Geschlechterstereotypen in Paarbeziehungen sein oder der Blick aus der Kriminologie auf den Einfluss von Normen und religiösen Werten; das sind negative und positive Auswirkungen von Aggression im Straßenverkehr oder die Frage nach dem Schutz vor Aggression in (sozialen) Medien; und der Blick aus der Biologie beleuchtet auch die Frage, wo Aggression ein Teil der Tierwelt ist und letztlich auch die Reflexion über unser Leben ermöglicht.

description: Optical interferometry provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Through direct observation of rotationally distorted photospheres at sub-milliarcsecond scales, we are now able to characterize latitude dependencies of stellar radius, temperature structure, and even energy transport. These detailed new views of stars are leading to revised thinking in a broad array of associated topics, such as spectroscopy, stellar evolution, and exoplanet detection. As newly advanced techniques and instrumentation mature, this topic in astronomy is poised to greatly expand in depth and influence.

description: The present study was an examination of the differences in 15 self-concept domains among special groups of adolescent students. Two self-concept scales were used: the Self-Perception Profile for Learning Disabled Students (SPPLD) and the Pyryt Mendaglio Self-Perception Survey (PMSPS). The sample consisted of 54 students who were gifted, 30 as having learning disabilities, 21 students who were gifted and had learning disabilities, and 43 regular class students. Correlations between two self-concept scales were also observed as a measure of concurrent validity. Results from the SPPLD revealed that students who had learning disabilities were significantly different from other groups of students on perceived general intellectual ability as well as perceived reading competence. No differences on the self-concept domains were found for the PMS PS across the groups of students. Correlations between self-concept scales suggest similar constructs were measured, confirming validity of results.

description: Our new formulation of the Spherical Collapse Model (SCM-L) takes into account the presence of angular momentum associated with the motion of galaxy groups infalling towards the centre of galaxy clusters. The angular momentum is responsible for an additional term in the dynamical equation which is useful to describe the evolution of the clusters in the non-equilibrium region which is investigated in the present paper. Our SCM-L can be used to predict the profiles of several strategic dynamical quantities as the radial and tangential velocities of member galaxies, and the total cluster mass. A good understanding of the non-equilibrium region is important since it is the natural scenario where to study the infall in galaxy clusters and the accretion phenomena present in these objects. Our results corroborate previous estimates and are in very good agreement with the analysis of recent observations and of simulated clusters.

description: In-hand object reorientation is necessary for performing many dexterous manipulation tasks, such as tool use in less structured environments that remain beyond the reach of current robots. Prior works built reorientation systems assuming one or many of the following: reorienting only specific objects with simple shapes, limited range of reorientation, slow or quasistatic manipulation, simulation-only results, the need for specialized and costly sensor suites, and other constraints which make the system infeasible for real-world deployment. We present a general object reorientation controller that does not make these assumptions. It uses readings from a single commodity depth camera to dynamically reorient complex and new object shapes by any rotation in real-time, with the median reorientation time being close to seven seconds. The controller is trained using reinforcement learning in simulation and evaluated in the real world on new object shapes not used for training, including the most challenging scenario of reorienting objects held in the air by a downward-facing hand that must counteract gravity during reorientation. Our hardware platform only uses open-source components that cost less than five thousand dollars. Although we demonstrate the ability to overcome assumptions in prior work, there is ample scope for improving absolute performance. For instance, the challenging duck-shaped object not used for training was dropped in 56 percent of the trials. When it was not dropped, our controller reoriented the object within 0.4 radians (23 degrees) 75 percent of the time. Videos are available at: https://taochenshh.github.io/projects/visual-dexterity.

description: The observed ultraviolet continuum (UVC) slope is potentially a powerful diagnostic of dust obscuration in star forming galaxies. However, the intrinsic slope is also sensitive to the form of the stellar initial mass function (IMF) and to the recent star formation and metal enrichment histories of a galaxy. Using the galform semi-analytical model of galaxy formation, we investigate the intrinsic distribution of UVC slopes. For star-forming galaxies, we find that the intrinsic distribution of UVC slopes at z=0, parameterised by the power law index beta, has a standard deviation of sigma_beta=0.30. This suggests an uncertainty on the inferred UV attenuation of A_fuv=0.7$ (assuming a Calzetti attenuation curve) for an individual object, even with perfect photometry. Furthermore, we find that the intrinsic UVC slope correlates with star formation rate, intrinsic UV luminosity, stellar mass and redshift. These correlations have implications for the interpretation of trends in the observed UVC slope with these quantities irrespective of the sample size or quality of the photometry. Our results suggest that in some cases the attenuation by dust has been incorrectly estimated.

description: This Master's Degree Project explores the potential of architecture as a facilitator. It attempts to understand the role of the Architecture of the Everyday, our Community Centres in promoting cultural connections and exchanges in our communities. By using the game of cricket, a form of cultural expression as a starting point, relationships between the game, culture, community, community buildings, and urban parks are explored in the thesis. These explorations combined with an understanding of the site, acquired by means of an extensive site analysis helps develop architectural strategies that culminate in the design of a Community + Recreation Centre, a Cricket Clubhouse, and a Viewing Shelter. The interventions intend to facilitate a richer cultural dialogue at the site and transform Riley Park into a cultural catalyst.

description: We study the Landau-gauge Gribov ghost form-factor sigma(p^2) for SU(N) Yang-Mills theories in the d-dimensional case. We find a qualitatively different behavior for d=3,4 w.r.t. d=2. In particular, considering any (sufficiently regular) gluon propagator D(p^2) and the one-loop-corrected ghost propagator G(p^2), we prove in the 2d case that sigma(p^2) blows up in the infrared limit p -> 0 as -D(0)\ln(p^2). Thus, for d=2, the no-pole condition σ(p^2) < 1 (for p^2 > 0) can be satisfied only if D(0) = 0. On the contrary, in d=3 and 4, sigma(p^2) is finite also if D(0) > 0. The same results are obtained by evaluating G(p^2) explicitly at one loop, using fitting forms for D(p^2) that describe well the numerical data of D(p^2) in d=2,3,4 in the SU(2) case. These evaluations also show that, if one considers the coupling constant g^2 as a free parameter, G(p^2) admits a one-parameter family of behaviors (labelled by g^2), in agreement with Boucaud et al. In this case the condition sigma(0) <= 1 implies g^2 <= g^2_c, where g^2_c is a 'critical' value. Moreover, a free-like G(p^2) in the infrared limit is obtained for any value of g^2 < g^2_c, while for g^2 = g^2_c one finds an infrared-enhanced G(p^2). Finally, we analyze the Dyson-Schwinger equation (DSE) for sigma(p^2) and show that, for infrared-finite ghost-gluon vertices, one can bound sigma(p^2). Using these bounds we find again that only in the d=2 case does one need to impose D(0) = 0 in order to satisfy the no-pole condition. The d=2 result is also supported by an analysis of the DSE using a spectral representation for G(p^2). Thus, if the no-pole condition is imposed, solving the d=2 DSE cannot lead to a massive behavior for D(p^2). These results apply to any Gribov copy inside the so-called first Gribov horizon, i.e. the 2d result D(0) = 0 is not affected by Gribov noise. These findings are also in agreement with lattice data.

description: Heterogeneous graph neural networks (HGNNs) were proposed for representation learning on structural data with multiple types of nodes and edges. To deal with the performance degradation issue when HGNNs become deep, researchers combine metapaths into HGNNs to associate nodes closely related in semantics but far apart in the graph. However, existing metapath-based models suffer from either information loss or high computation costs. To address these problems, we present a novel Metapath Context Convolution-based Heterogeneous Graph Neural Network (MECCH). MECCH leverages metapath contexts, a new kind of graph structure that facilitates lossless node information aggregation while avoiding any redundancy. Specifically, MECCH applies three novel components after feature preprocessing to extract comprehensive information from the input graph efficiently: (1) metapath context construction, (2) metapath context encoder, and (3) convolutional metapath fusion. Experiments on five real-world heterogeneous graph datasets for node classification and link prediction show that MECCH achieves superior prediction accuracy compared with state-of-the-art baselines with improved computational efficiency.

description: Polyimides (PI) are a class of dielectric polymer used in a wide range of electronics and electrical engineering applications from low-voltage microelectronics to high voltage isolation. They are well appreciated because of their excellent thermal, electrical, and mechanical properties, each of which need to be optimized uniquely depending on the end application. For example, for high-voltage applications, the final polymer breakdown field and dielectric properties must be optimized, both of which are dependent on the curing process and the final physico-chemical properties of PI. The majority of studies to date have focused on a limited set of properties of the polymer and have analyzed the effect of curing from a physicochemical-, mechanical- or electrical?centric viewpoint. This paper seeks to overcome this, unifying all of these characterizations in the same study to accurately describe the universal effect of the cure temperature on the properties of PI and at an industrial processing scale. This paper reports the widest-ranging study of its kind on the effect that cure temperature has on the physico-chemical, mechanical, thermal and electrical properties of polyimide, specifically poly (pyromellitic dianhydride-co-4, 40 -oxydianiline) (PMDA/ODA). The optimization of the cure temperature is accurately studied not only regarding the degree of imidization (DOI), but also considering the entire physical properties. Particularly, the analysis elucidates the key role of the charge–transfer complex (CTC) on these properties. The results show that while the thermal and mechanical properties improve with both DOI and CTC formation, the electrical properties, particularly at high field conditions, show an antagonistic behavior enhancing with increasing DOI while degrading at higher temperatures as the CTC formation increases. The electrical characterization at low field presents an enhancement of the final PI properties likely due to the DOI. On the contrary, at high electric field, the conductivity results show an improvement at an intermediate temperature emphasizing an ideal compromise between a high DOI and PI chain packing when the thermal imidization process is performed over this equilibrium. This balance enables maximum performance to be obtained for the PI film with optimized electrical properties and, overall, optimal thermal and mechanical properties are achieved.

description: An accurate knowledge of the lattice parameters of the new nitride Sc$_\textit{x}$Al$_\textit{1-x}$N is essential for understanding the elastic and piezoelectric properties of this compound as well as for the ability to engineer its strain state in heterostructures. Using high-resolution x-ray diffractometry, we determine the lattice parameters of 100-nm-thick undoped Sc$_\textit{x}$Al$_\textit{1-x}$N layers grown on GaN(0001) templates by plasma-assisted molecular beam epitaxy. The Sc content $\textit{x}$ of the layers is measured independently by both x-ray photoelectron spectroscopy and energy-dispersive x-ray spectroscopy and ranges from 0 to 0.25. The in-plane lattice parameter of the layers linearly increases with increasing $\textit{x}$, while their out-of-plane lattice parameter remains constant. Layers with $\textit{x}$ $\approx$ 0.09 are found to be lattice matched to GaN, resulting in a smooth surface and a structural perfection equivalent to that of the GaN underlayer. In addition, a two-dimensional electron gas is induced at the Sc$_\textit{x}$Al$_\textit{1-x}$N/GaN heterointerface, with the highest sheet electron density and mobility observed for lattice-matched conditions.

description: Using new Keck DEIMOS spectroscopy, we examine the origin of the steep number counts of ultra-faint emission-line galaxies recently reported by Dressler et al. (2011). We confirm six Lyman Alpha emitters (LAEs), three of which have significant asymmetric line profiles with prominent wings extending 300-400 km/s redward of the peak emission. With these six LAEs, we revise our previous estimate of the number of faint LAEs in the Dressler et al. survey. Combining these data with the density of bright LAEs in the Cosmic Origins Survey and Subaru Deep Field provides the best constraints to date on the redshift 5.7 LAE luminosity function (LF). Schechter function parameters, phi^* = 4.5 x 10^{-4} Mpc^{-3}, L^* = 9.1 x 10^{42} erg s^{-1}, and alpha= -1.70, are estimated using a maximum likelihood technique with a model for slit losses. To place this result in the context of the UV-selected galaxy population, we investigate how various parameterizations of the Lyman Alpha equivalent width distribution, along with the measured UV-continuum LF, affect shape and normalization of the Lyman Alpha LF. The nominal model, which uses z~6 equivalent widths from the literature, falls short of the observed space density of LAEs at the bright end, possibly indicating a need for higher equivalent widths. This parameterization of the equivalent width distribution implies that as many as 50% of our faintest LAEs should have M_{UV} > -18.0, rendering them undetectable in even the deepest Hubble Space Telescope surveys at this redshift. Hence, ultra-deep emission-line surveys find some of the faintest galaxies ever observed at the end of the reionization epoch. Such faint galaxies likely enrich the intergalactic medium with metals and maintain its ionized state. Observations of these objects provide a glimpse of the building blocks of present-day galaxies at an early time.

description: The MIRS software for the modeling of ro-vibrational spectra of polyatomic molecules was considerably extended and improved. The original version (Nikitin, et al. JQSRT, 2003, pp. 239--249) was especially designed for separate or simultaneous treatments of complex band systems of polyatomic molecules. It was set up in the frame of effective polyad models by using algorithms based on advanced group theory algebra to take full account of symmetry properties. It has been successfully used for predictions and data fitting (positions and intensities) of numerous spectra of symmetric and spherical top molecules within the vibration extrapolation scheme. The new version offers more advanced possibilities for spectra calculations and modeling by getting rid of several previous limitations particularly for the size of polyads and the number of tensors involved. It allows dealing with overlapping polyads and includes more efficient and faster algorithms for the calculation of coefficients related to molecular symmetry properties (6C, 9C and 12C symbols for C_{3v}, T_{d}, and O_{h} point groups) and for better convergence of least-square-fit iterations as well. The new version is not limited to polyad effective models. It also allows direct predictions using full ab initio ro-vibrational normal mode hamiltonians converted into the irreducible tensor form. Illustrative examples on CH_{3} D, CH_{4}, CH_{3} Cl, CH_{3} F and PH_{3} are reported reflecting the present status of data available. It is written in C++ for standard PC computer operating under Windows.

description: We have used scanning tunneling microscopy to study the structure of graphene islands on Au(111) grown by deposition of elemental carbon at 950°C. Consistent with low-energy electron microscopic observations, we find that the graphene islands have dendritic shapes. The islands tend to cover depressed regions of the Au surface, suggesting that Au is displaced as the graphene grows. If small tunneling currents are used, it is possible to image simultaneously the graphene/Au moiré and the Au herringbone reconstruction, which forms underneath the graphene on cooling from the growth temperature. The delicate herringbone structure and its periodicity remain unchanged from the bare Au surface. Using a Frenkel-Kontorova model we deduce that this striking observation is consistent with an attraction between graphene and Au of less than 13 meV per C atom. Raman spectroscopy supports this weak interaction. However, at the tunneling currents necessary for atomic resolution image of graphene, the Au reconstruction is altered, implying influential tip-sample interactions and a mobile Au surface beneath the graphene.

description: The introduction to the panel discussion brings up the question of how it is possible to write the history of music – mostly, but not exclusively, that of the tradition of Western art music – in an age in which the historical perspective is no longer given precedence over theoretical-synchronic and ethno-anthropological approaches. To this purpose, it proposes a list of ‘key words’, from which participants are invited to reflect upon the problems they have faced in their endeavour to write handbooks and the issues arising from experiences of use and reception of their work.

description: An approach to evolutionary ensemble learning for classification is proposed in which boosting is used to construct a stack of programs. Each application of boosting identifies a single champion and a residual dataset, i.e. the training records that thus far were not correctly classified. The next program is only trained against the residual, with the process iterating until some maximum ensemble size or no further residual remains. Training against a residual dataset actively reduces the cost of training. Deploying the ensemble as a stack also means that only one classifier might be necessary to make a prediction, so improving interpretability. Benchmarking studies are conducted to illustrate competitiveness with the prediction accuracy of current state-of-the-art evolutionary ensemble learning algorithms, while providing solutions that are orders of magnitude simpler. Further benchmarking with a high cardinality dataset indicates that the proposed method is also more accurate and efficient than XGBoost.

Gravitation as a pressure force: a scalar ether theory
Creators: name: Arminjon, Mayeul
Publisher: name: arXiv
Year: 2011
Subjects: subject: General Physics (physics.gen-ph)

description: If the presence of a gravitational field breaks the Lorentz symmetry valid for special relativity, an "absolute motion" might be detectable. We summarize a scalar theory of gravity with a such "ether", which starts from a tentative interpretation of gravity as a pressure force. The theory also admits that our physical standards of space and time are affected by gravitation similarly as they are affected by a uniform motion. General motion is governed by an extension of Newton's second law to the curved space-time which is thus obtained. Together with the scalar field equation of the theory, this leads to a true conservation equation for the total energy. The law of motion also leads to an alternative 4-component equation governing the dynamics of a continuum in terms of its energy-momentum tensor. That new equation implies that mass conservation is obtained as a limiting behaviour for a weak and slowly varying gravitational field and/or at a low pressure. In the presence of the Lorentz force field, the new dynamical equation gives the second group of the gravitationally-modified Maxwell equations in the investigated theory. This is consistent with the geometrical optics of the theory as governed by the proposed extension of Newton's second law. The theory has the correct Newtonian limit; it predicts Schwarzschild's exterior metric of general relativity and geodesic motion in the static situation with spherical symmetry. A post-Newtonian approximation of this theory shows that no preferred-frame effect occurs for photons at the (first) post-Newtonian approximation. It is argued that the existence of preferred-frame effects in celestial mechanics, comparable in magnitude with the "relativistic" effects, does not a priori invalidate the theory.

“De stilo et opere”; or, Looking for the Rule
Creators: name: Goehring, Edmund J.
Publisher: name: Dipartimento delle Arti - Alma Mater Studiorum - Università di Bologna
Year: 2015
Subjects: music history; education

description: Ever since Kant, we have thought of the rule guiding an exemplary and original work of art as contained within the work itself, discovered not prior to but in the act of composition itself. Everything else is copy. This paper weighs that position against a tendency in the teaching of music history which subordinates the individual work to general style. It concludes with examples of what it might look like to study a musical work by looking for its rule.

description: Additional file 5: Table S2. For the neuropsychological tests that have too few samples, the average salient administered fraction (SAF) and standard deviation for true positive (SAF[+]) and true negative (SAF[-]) cases are listed in descending order based on the SAF[+] value. SAF[+] is calculated by summing up the time spent in a given neuropsychological test that intersects with a segment of time that is DE[+] salient and dividing by the total time spent in a given neuropsychological test. SAF[-] is calculated by summing up the time spent in a given neuropsychological test that intersects with a segment of time that is not DE[+] salient and dividing by the total time spent in a given neuropsychological test. The number of samples for SAF[+] and SAF[-] indicate the number of true positive and true negative recordings that contain each neuropsychological test.

description: Symplectic instanton vector bundles on the projective space $\mathbb{P}^3$ constitute a natural generalization of mathematical instantons of rank 2. We study the moduli space $I_{n,r}$ of rank-$2r$ symplectic instanton vector bundles on $\mathbb{P}^3$ with $r\ge2$ and second Chern class $n\ge r,\ n\equiv r({\rm mod}2)$. We give an explicit construction of an irreducible component $I^*_{n,r}$ of this space for each such value of $n$ and show that $I^*_{n,r}$ has the expected dimension $4n(r+1)-r(2r+1)$.

«Cercate l’antica madre»: percorsi e ricorsi delle forme musicali medievali
Creators: name: Ruini, Cesarino
Publisher: name: Dipartimento delle Arti - Alma Mater Studiorum - Università di Bologna
Year: 2015
Subjects: forme musicali medievali

description: In is fairly usual for music history handbooks to introduce certain remote musical forms, documented since the historical period in which they became established, with an adequate formal analytical support. What they entirely lack, often due to problems retrieving documentation, is any explanation concerning their origin and the genetic process of their evolution.

Such an approach leads to a ‘sterilized’ comprehension of the musical phenomenon, by depriving it of the essential contribution of its social and cultural context.

Through a couple of examples, the article shows how restoring the historical identity of musical forms that are no longer current can also reconstruct the traits that are able to convey authentic meanings to us and our descendants.

On the nature of the Herbig B[e] star binary system V921 Scorpii: Discovery of a close companion and relation to the large-scale bipolar nebula

description: Belonging to the group of B[e] stars, V921 Scorpii is associated with a strong infrared excess and permitted and forbidden line emission, indicating the presence of low- and high-density circumstellar gas and dust. Many aspects of V921 Sco and other B[e] stars still remain mysterious, including their evolutionary state and the physical conditions resulting in the class-defining characteristics. In this paper, we employ VLTI/AMBER spectro-interferometry in order to reconstruct high-resolution (lambda/2B=0.0013") model-independent interferometric images for three wavelength bands around 1.65, 2.0, and 2.3 micrometer. In our images, we discover a close (25.0+/-0.8 milliarcsecond, corresponding to 29+/-0.9 AU at 1.15 kpc) companion around V921 Sco. Between two epochs in 2008 and 2009, we measure orbital motion of 7 degrees, implying an orbital period of about 35 years (for a circular orbit). Around the primary star, we detect a disk-like structure with indications for a radial temperature gradient. The polar axis of this AU-scale disk is aligned with the arcminute-scale bipolar nebula in which V921 Sco is embedded. Using Magellan/IMACS imaging, we detect multi-layered arc-shaped sub-structure in the nebula, suggesting episodic outflow activity from the system with a period of about 25 years, roughly matching the estimated orbital period of the companion. Our study supports the hypothesis that the B[e] phenomenon is related to dynamical interaction in a close binary system.

Die musiktheoretische Ergründung der Arienform in italienischen Opern des 18. Jahrhunderts und die Umgestaltung des Fachs Formenlehre

Subjects: aria; Russia; instrumental music; opera

description: The paper focuses on the issue of the role played by the 18th Century Italian aria within the general system of musical forms. This question is relevant for both music theory and pedagogy. Did the aria influence instrumental genres or was it the opposite?
Throughout the history of professional musical education in Russia (from the 19th century to the present day), both general music theory and courses in musical form have usually been based on instrumental music. However, studies in recent decades show that, in the process of crystallization of a number of structures and principles of composition in the first half of the 18th century, the aria takes a prominent position. Among these are such principles as the ritornello, which underlies the Baroque concerto; principles of recapitulation and ternary form that became established in Italian arias in the 1680s (earlier than in the instrumental genres), as well as the principle of thematic contrast. Italian opera played a key role in the formation of classical musical Thematik (Ger.) - not only in its lexical topoi, but also in the treatment of homophony, metric and syntactic periodicity, and the fractionality of motivic structure. The development of the two-subjects sonata form took place within the framework of da capo arias simultaneously with instrumental music (1720-1750s). The Italian aria played a decisive role in the birth of the sonata form with two initial sections typical of the classic concerto.
In the musical form course for musicologists and musicians-performers at the Russian Gnessins Academy of Music, I discuss the theory and history of music forms during the 17th and 18 th centuries, taking into account all these factors. This method introduces significant adjustments in the traditional practice of music form teaching in Russia, thereby bringing the understanding of students closer to the real processes that occurred in the music history of the 18th century.
