Composition 2020.01 (Barbara Hepworth) is forty-two minutes and forty seconds in duration - and was digitally produced using FM synthesis. The components of the composition consist of the artist Barbara Hepworth reading from her diary - ‘It took a long time for me to find my own personal way of making sculpture. A long time to discover the purest forms that would exactly evoke my own sensations - and to visualise images which would express the timelessness of primitive forces which I felt - and the constant urge towards survival - and growth - which I knew to be fundamental - both to the human being and the landscape in which we stand’. In addition - there is a one-bar sound that repeats every sixty-four bars - a sixty-four-bar sound that repeats every one-hundred-and-twenty-eight bars - a sixty-four-bar sound that repeats every two-hundred-and-fifty-six bars - and a low frequency sinewave-based tone - pitched at C1 - that continues throughout the duration of the composition. Ring-modulation has been applied to some of the elements to create a level of harmonic complexity.
