Michael Cooper asks: >Can anyone cite specific examples of (preferably classical) music wherein >there is a denominator in the time signature that is not a power of two >(of course, one=two to the zero power). No. Although there are half-notes and quarter-notes, there's no such thing as a "third-note." Think about it. What's the notational symbol for it? If you're talking about the "numerator," however, there are lots of examples, some of them quite famous. Steve Schwartz
