The notion for Encapsulations is that mid-term memory (or working memory) influences our music appreciation, and the ambition is to make this a feature of the composition itself. For that reason, the live computer records the solo accordion in real-time, re-inserting it into the musical ongoings in different forms that resemble the ‘colourings’ which memory does. This can be as full chunks of time and bands of frequencies (from less that two and up to six-seven seconds), and as more vague recollections as re-synthesis of the ‘mined’ material. The result is akin to sets of diapositives of the musical past that can slide across the presence.

For this reason, the computer does not make use of the common procedure of processing and enlarging the live instrument, but must instead sound as a diistinct sound-source. The selection and re-creation by the computer is handled by the composer through dedicated programming, and the resulting amalgam consequently holds an added element of ‘instant composition’ that unfolds in conjunction with ‘distributed composition’ of the fully written-out accordion part, performed by the soloist.

Encapsulations was composed 2019 as a commissioned by Peter Katina, to whom it is dedicated.
