What is serious is that you seem incapable of either admitting that your statement is incorrect, or explaining what you mean.

Are you stil disagreeing with that?

Then in this most recent response, you did 180 and said that it is, in fact, not relevant.

In terms of semantics, numerals and note representation operate exactly the same. There is a 1-1 mapping between numbers interpreted as fractions of a whole note, and the graphical symbols used to represent those durations/lengths. What makes you say that tuplet notation is incorrect semantics by my classification?

Don't blame this on others. When you are shown to be incorrect about something, you seem incapable of either admitting that you were either wrong, or were unclear about what it was you were saying in the first place. You could have simply explained what you mean about the subdivision "problem" but instead you have both contradicted yourself, and not explained it. If you were trying to help, you would not be berating people for thinking that the lilypond "duration" actually models what we all understand about duration both in common language usage, as well as musical usage. Now, if I am going to try to salvage this conversation, I will try to summarize: * No one knows what your comment about subdivision means, so please either retract it, or clarify how it pertains to 8/20 but not 6/8. * If there are, as you claim, multiple ways of representing 1/20 of a whole note graphically, then are you saying the entire concept/request is flawed because of this, or just that the problem/feature is larger than anticipated because some degree of control over the representation is needed? * What is the best place to learn about the duration/moment topic?
