The Recently Issued Recording of Simpson's Eighth String Quartet has given us an opportunity to examine a change in that composer's approach to large-scale form. He himself mentioned this ‘new way’—without using such a Beethovenian expression—in a BBC Radio 3 discussion with Michael Oliver, on 6 November 1982:
In earlier times I was interested in large-scale tonality, large areas of tonality: but now I'm trying to find what intervals themselves can generate, using the resonances inherent in simple intervals like the fifth, the fourth or the third. I try to generate something from that by feeling it in a novel way, by approaching the interval of a fifth as if I had never heard it before, and trying to find what can happen—or by using intervals against each other. Take two intervals, the second and the fifth; then you have a combination of intervals and you can use them in different ways against each other.
