A look at the conductor score for Frank Zappa's "Bob in Dacron and Sad Jane" and some of the perceived musical problems.

NOTE: At 01:32 in this video, I discuss 2 bars consisting of 11/16 and 15/16 and how these could be interpreted as substitutions for 11:4 and 15:4. Just to clarify, although these 2 bars could be interpreted as substitutions for facilitating the "economy of means", they do not share the same time space. The 11/16 will occupy less time than the 11:4 because in 11/16, the denominator is simply a division, and therefore the 11 semiquavers are just that, not actually 11 in the time of 16, which is why it occupies less time, because we are not getting the full 11 against 16, rather 11 against 11 in this context. Therefore, the 11:4 means the 11 is played in the time of 16, which is why it would occupy more time, this of course also applies to the 15/16 and 15:4 interpretations.
