Learning Nancarrow’s Canon A (5/7)
Ursula Oppens told me that she subdivided each bar into 35 parts. This seems at once sensible and totally ridiculous.
5 = 2+3; 7 = 2+2+3; think of each bar as a 3 against 2 but with one of the beats elongated.
Meter more about inflection than precision of duration.
