Time and Ensemble Dynamics in Indeterminacy: John Cage’s Concert for Piano and Orchestra

This chapter examines ensemble dynamics and time consciousness in indeterminate music, using John Cage’s Concert for Piano and Orchestra (1957–8) as a case study. Drawing on interviews and observational studies undertaken with the experimental music ensemble Apartment House, I examine the role of temporal indeterminacy in the socio-musical interactions that characterize performance, and its implications for the musicians’ experiences. In doing so, the chapter makes a broader contribution in its consideration of the ways in which issues of authorship and authority are negotiated in such temporal interactions, and how the dynamics of these negotiations present a sociality based on a ‘separate togetherness’, whereby performers play together (out of time) with one another.

Symbolism of the renaissance sculpture: Aedicule of Sholts-Volfovych townhouse in Lviv

The specific conditions of architectural development in Lviv promoted the expansion of the Renaissance traditions in the architecture in the XVI century. The local traditions considerably influenced the classical forms as well as techniques suggested by the Italian architects. As a result, the architecture of Lviv had taken the peculiar features that reflected the character of an indigenous revival. A significant feature of a Renaissance townhouse in Lviv lies in its abundant decoration. as it was created according to the symbolic ideas and was filled with the philosophic content. The façade of Sholts-Volfovych apartment house situated in 23, Rynok Square in Lviv deserves special attention. The abundant exterior design includes the composition «Epiphany», located in the aedicule of the second floor. Using the principle of hermeneutics the article presents the author’s interpretation of a symbolic meaning of this sculptural composition, based on the Gospel texts and is connected with the Renaissance meditations about a human place in the world and his/her relationship with God.

Ensemble interaction in indeterminate music

Examining ensemble interaction in the music of experimental composer Christian Wolff, this chapter uses as a case study a professional recording session undertaken by the ensemble Apartment House of <em>Exercises</em> (1973–2013), a series of pieces for (mostly) unspecified instrumentation and numbers of players. Wolff’s skeletal notation is deliberately under-determined, acting like something of a puzzle to be solved. Consequently, the players must negotiate a way of working with the notation and with each other, making decisions prior to, and during, the moment of performance. Drawing on interviews and observational studies, the chapter identifies three different forms of interaction in the musicians’ playing as they engaged with Wolff’s notation: working responsively, independently, and emergently. The chapter offers a view of ensemble interaction that is characterized by cooperation, but also uncertainty, surprise, or even complete breakdown.

ANALYSIS OF THE AIRTIGHTNESS MEASUREMENT IN SINGLE OR DOUBLE APARTMENT HOUSE

The mandatory energy performance certification of new buildings or buildings for sale has been introduced in all Member States in order to achieve European Union’s energy efficiency goals. The certification of buildings sets mandatory requirements for higher energy efficiency buildings’ level of airtightness. However, a bigger problem lies in existing older residential buildings, which are energy inefficient and do not require certification. The unused potential for energy savings observed here is related to the airtightness of single and double apartment residential buildings and energy efficiency related to airtightness of them. Therefore, this work analyses the airtightness of energy class D and lower buildings based on actual airtightness measurements and evaluates the possible energy saving potential associated with the application of airtightness measures based on the example of one inefficient single apartment building. The results show that increase of the airtightness in such buildings to 3 h–1 enables to reduce the energy costs related to the airtightness in Lithuania over a period of 10 years by 0.17 TWh per year.

A comparison of small-area deprivation indicators for public-health surveillance in Sweden

Aims: The aims of this study were to construct a small-area index of multiple deprivation (IMD) from single deprivation indicators (SDIs) and to compare the explanatory power of the IMD and SDIs with regard to mortality. We considered a small-area division of Sweden consisting of 5985 DeSO ( Demografiska statistikområden), each with a population size between 653 and 4243 at the end of 2018. Methods: Four SDIs were provided by open-source data: (a) the proportion of inhabitants with a low economic standard; (b) the proportion of inhabitants aged 25–64 years with ⩽12 years of schooling; (c) the proportion of inhabitants aged 16–64 years who were not in paid employment; and (d) the proportion of inhabitants who lived in a rented apartment/house. A four-indicator IMD was constructed using factor analysis. As a validation, the IMD and SDIs were compared by exploring their DeSO-level associations with spatially smoothed death rates, with robustness checks of associations across different small-area contexts defined by degree of urbanisation and distribution of immigrants from non-Western countries. Results: The constructed IMD and SDI1 performed essentially equally and outperformed SDI2, SDI3 and SDI4. Associations between IMD/SDI1 and the spatially smoothed death rates were most pronounced within the age range 60–79 years, showing 5–8% lowered rates among those categorised in the least deprived quintiles of IMD and SDI1, respectively, and 7–9% elevated rates among those categorised in the most deprived quintiles. These associations were consistent within each small-area context. Conclusions: We suggest prioritisation of SDI1, that is, a DeSO-level deprivation indicator based on open-access data on economic standard, for public-health surveillance in Sweden.
