    There’s a lot of talk about the virtual impossibility of performing Ferneyhough’s scores; the usual strategy is to parse them into individual beats, learning them beat by beat, bar by bar, like a new language. The first measure of this piece, for example, is 7/16. Those 7...

    beats are bracketed, and the bracket is labeled 11:7 -- that is, eleven beats in the time of seven. Three of those 11 are bracketed with the label 5:3, meaning 5 beats fit in where three had. And within the 5:3, there are two divisions, a group labeled 5:3 and one labeled 7:4; and within the first of those, there is a further division 5:3. So the second sixteenth note of the piece is actually in a ratio of (5/3) / (5/3) / (5/3) / (11/7) in relation to the original beat. This is clearly a strategy made possible by computer software, which makes these kinds of divisions fun and easy. It is easier to understand, and to learn, if it's thought of as a product of the software.
