Abstract Founded in 2016 at Université de Montréal, Ensemble d’oscillateurs (French for Oscillator Ensemble) brings together ten musicians around old analog test equipment oscillators that produce audio sine waves. The ensemble performs new compositions while also arranging early electronic pieces. In parallel, the project developed itself as a space to gather information and reflect on sine wave-based music. This article presents some of the key considerations and challenges in the formation of Ensemble d’oscillateurs. Based on the observations made throughout the development of a body of work using these audio oscillators, it then aims to open a discussion on some aspects of the historical trajectory of the use of sine waves in modern music.

The Future

Nowadays, various test equipment tend to be more intelligent, the test equipment of the volt-ampere characteristic of CT is so too. As the development of the electronics, VLSI(SCM) is manufactured. The purpose of our project is to scheme out a intelligent test system by the computer technique and the test technique. This equipment is mostly made of the SCM system and the peripheral equipment. We control the output of the digital transformer by SCM. The output voltage can make the TL494 create PWM wave. The wave is the control signal of the main circuit. The output wave of the main circuit is the sine wave, and the value of the output can be amended automatically. Compared with the traditional equipment, this equipment is smaller and use less energy, but its function is more powerful. It can be programmable. We can take it more expediently. So, this kind of equipment can be used widely in the future.

Abstrak Alat uji Marshall digunakan untuk mengetahui stabilitas terhadap kelelehan plastis (flow) dan MQ dari lapis perkerasan AC-BC. Tipe alat pengujian Marshall dapat berupa analog dan digital. Alat uji analog dengan pembacaan data manual sangat bergantung pada ketrampilan operator. Alat uji digital menggunakan sistem komputer, sehingga menghasilkan data maksimum dengan operator minimum. Penelitian dilaksanakan berdasarkan SNI 06-2489-1991 pada campuran AC-BC dengan lima variasi kadar aspal. Hasil pengujian didapatkan nilai rata-rata alat uji analog pengamatan langsung: stabilitas (kg) = 1490,49; Flow (mm) = 4,48; MQ (kg/mm) = 335,55. Alat uji analog pengamatan perekaman video: stabilitas (kg) = 1482,91; Flow (mm) = 4,44; MQ (kg/mm) = 336,48. untuk alat uji digital menghasilkan stabilitas (kg) = 1508,36; Flow (mm) = 4,42; MQ (kg/mm) = 342,93. Berdasarkan analisa perbedaan tiga rata-rata menunjukkan tidak terdapat perbedaan signifikan hasil pengujian menggunakan alat uji Marshall analog pengamatan langsung, perekaman video dan digital. Kata kunci: campuran AC-BC, karakteristik Marshall, alat uji marshall analog dan digital Abstract Marshall test-equipment is used to determine the stability of the flow and MQ of AC-BC pavement. It can be an analog and a digital test-equipment. Analog test-equipment reading the data manually dependens on the operator skills. While the digital test equipment uses a computer system produces maximum data with minimum operator. The research is conducted based on a mixture SNI 06-2489-1991 AC-BC with five variation of asphalt content. The presumptions of the test result of Marshall characteristic are found out as: the direct observation-analogue gets the stability (kg) = 1490.49; Flow (mm) = 4.48; MQ (kg / mm) = 335.55. The visualization analogue gets the stability (kg) = 1482.91; Flow (mm) = 4.44; MQ (kg / mm) = 336.48. The digital test-equipment gets the stability (kg) 1508.36; Flow (mm) = 4.42; MQ (kg / mm) = 342.93. Based on the three different analysis evenly show that there are no different significantly from the test result by using the direct observation-analogue, the visualization analogue, and the digital Marshall test-equipment.

Abstract. Five overlapping eras or stages can be distinguished in the evolution of music therapy. The first one refers to the historical roots and ethnological sources that have influenced modern meta-theoretical perspectives and practices. The next stage marks the heterogeneous origins of modern music therapy in the 20th century that mirror psychological positions and novel clinical ideas about the healing power of music. The subsequent heyday of music therapeutic models and schools of thought yielded an enormous variety of concepts and methods such as Nordoff–Robbins music therapy, Orff music therapy, analytic music therapy, regulatory music therapy, guided imagery and music, sound work, etc. As music therapy gained in international importance, clinical applications required research on its therapeutic efficacy. According to standards of evidence-based medicine and with regard to clearly defined diagnoses, research on music therapeutic practice was the core of the fourth stage of evolution. The current stage is characterized by the emerging epistemological dissatisfaction with the paradigmatic reductionism of evidence-based medicine and by the strong will to discover the true healing nature of music. This trend has given birth to a wide spectrum of interdisciplinary hermeneutics for novel foundations of music therapy. Epigenetics, neuroplasticity, regulatory and chronobiological sciences, quantum physical philosophies, universal harmonies, spiritual and religious views, and the cultural anthropological phenomenon of esthetics and creativity have become guiding principles. This article should not be regarded as a historical treatise but rather as an attempt to identify theoretical landmarks in the evolution of modern music therapy and to elucidate the evolution of its spirit.

The main objective of this study is the substantiation of experiment as one of the key features of the world music in Ukraine. Based on the creative works of the brightest world music representatives in Ukraine, «Dakha Brakha» band, the experiment is regarded as a kind of creative setting. Methodology and scientific approaches. The methodology was based on the music practice theory by T. Cherednychenko. The author distinguishes four binary oppositions, which can describe the musical practice. According to one of these oppositions («observance of the canon or violation of the canon»), the musical practices, to which the Ukrainian musicology usually classifies the world music («folk music» and «minstrel music»), are compared with the creative work of «Dakha Brakha» band. Study findings. A lack of the setting to experiment in the musical practices of the «folk music» and «minstrel music» separates the world music musical practice from them. Therefore, the world music is a separate type of musical practice in which the experiment is crucial. The study analyzed several scientific articles of Ukrainian musicologists on the world music; examined the history of the Ukrainian «Dakha Brakha» band; presented a list of the folk songs used in the fifth album «The Road» by «Dakha Brakha» band; and showed the degree of the source transformation by musicians based on the example of the «Monk» song. The study findings can be used to form a comprehensive understanding of the world music musical practice. The further studies may be related to clarification of the other parameters of the world music musical practice, and to determination of the experiment role in creative works of the other world music representatives, both Ukrainian and foreign. The practical study value is the ability to use its key provisions in the course of modern music in higher artistic schools of Ukraine. Originality / value. So far, the Ukrainian musicology did not consider the experiment role as the key one in the world music.
