"...världens skridskotystnad före Bach" : historiskt informerad uppförandepraxis ur ett kontextuellt musikontologiskt perspektiv, belyst genom en fallstudie av Sonat i E-dur, BWV 1035, av J S Bach

Sammanfattning: The aim of the present study is to explore the so-called historically informed performance movement, which also is my own musical performance tradition, from a general perspective grounded in musical philosophy. The discussions concerning this performance tradition have been dominated by different subjects, such as musical works, authenticity, intention and interpretation. The study focuses on Western art music where the performance of the music, the sounding realisation, of a notated work is central. Therefore, the performance in connection with the abovementioned subjects is of prime interest. This more overarching theme gave rise to the following questions: What factors can be considered decisive for whether a performance is a historically informed performance or not? How can these factors be identified? Does this mean that there are instructions in the music that I, as a musician, must obey? What does my artistic freedom look like? Where can I find it? The path to tentative answers to these questions is taken via theoretical discussions and the application of the theory in method and analyses as well as in interpretation.The theoretical perspective of the study is based on contextual musical ontology. The scientific theoretical framework, emanating from this ontology, is formulated in the field of social constructionism.The performance can, through this perspective, be identified as an indispensable part of the musical work, which also implies that the notated work itself is not sufficient to identify the work. Further, the emphasis on the context's importance for the performance in order to allow the performance to be of the work in question implies the necessity of awareness of the context of the work. This concept is deepened in the study through the emphasis on the importance for the performance, in a broad perspective, of the historical as well as the contemporary socio-cultural context. For the work itself this means that the identity of the work is unstable, it is constantly changing, since the different performances of the work that are parts of the work can never be identical. The perspective is based on social constructivist theories about knowledge. With contextual musical ontology as a point of departure, a strategy is formulated concerning analysis and investigation of a musical work. This strategy focuses on the notation, the instrumentation, and historical performance conventions. These three parts interact with one another and in the study they are formulated as being inseparable from the performance of the work.The theoretical part of the study is followed by a case study in which a sonata by Johann Sebastian Bach is studied from the articulated theoretical perspective. The case study contains an investigative part and an interpretative part. The work's notation is always in focus in the investigative and descriptive part, with emphasis on the socio-cultural context connected to the notation. Through the sounding interpretations, the different performances, the final chapter results in a summary of the study as a whole.
