Interpretation och dissonansbehandling på kromatisk nyckelharpa

By describing and analyzing a self made composition for the Swedish folk music instrument ?nyckelharpa? with emphasis on playing techique, dissonance treatment and interpretation questions are reflected upon regarding how dissonances and andvanced harmonical progressions are treated on a limited instrument such as ?nyckelharpa?. By emphasizing the traditional norm connected to the interpretation and instrumentation of traditional Swedish folk music (a traditon in which the nyckelharpa is included) and comparing the te- chniques connected to it with the recent composed material in a western classical context the possibilities and limitations in composition and interpretation are further investigated. Thus the musical experience and the documentation of the process of composing a concert for nyckelharpa provides a knowledge base for reflective analysis upon questions regarding interpretation, composition and dissonance treatment. This thesis also provides a brief summary of traditional playing and bowing technique as well as a short historical description of the Swedish traditional instrument ?nyckelharpa?..

Den bäcknära zonen vid små skogliga vattendrag i Värmland : generell beskrivning, förekomst av traktorspår samt kvicksilverhalter i körpåverkat ytvatten

Forest streams and the associated riparian zones are sensitive to disturbances and changes that occur within these riparian areas. Particularly sensitive are small streams of low order, which will have large impacts down-stream. The disturbances that occur in the riparian zones are reflected quickly in the stream. Driving with forestry machines in the riparian zone will have detrimental effects to the soil and water. Driving the machines will lead to changes in the mineral soil composition, resulting in the reduction of porosity, less infiltration, compaction, and an increased bulk density.

Moder Jord i kyrkorummet? : En undersökning av kopplingarna mellan det kristna och det fornnordiska i Vester Egede kyrkans dopfunt som objekt och vad angår motivval, tolkning och dopritual.

She is said to be a typical early roman Luxuria, in mild appearance. However, what makes her unique is that she appears standing on the top of her head, her womb serving as font. The main question is how come that a baptismal font like this is to be found in a church, leading to the sub question, if this font really has a Christian origin or could it be rooted in Norse, pre-Christian tradition, alternatively is the font an expression of a syncretism between the two colliding cultures.
