Mr. Payne:

 

My thanks to you and Mr. Kastrup for addressing my inquiry.

 

Please check my understanding. The "1" and the "4" refer to a quarter note,
the span over which the command "\times 2/3" acts. Therefore, in the example
(attached) the tuplets are in the span of a quarter note. If I had wanted
the tuplets over the spam of a 16th note, I would use "1" and "16." Am I
correct?

 

Thank you for your kind attention.

 

Mark

I understand everything except how the "1" and "4" relate to the notation.


Have a look at the section of the documentation on time administration
(http://lilypond.org/doc/v2.17/Documentation/notation/special-rhythmic-conce
rns#time-administration): "ly:make-moment n m constructs a duration of n/m
of a whole note. For example, ly:make-moment 1 8 is an eighth note duration
and ly:make-moment 7 16 is the duration of seven sixteenths notes."

BTW, both #(ly:make-moment 1 4) and #(ly:make-moment 1/4) are valid, and
both forms can be found in the documentation (see
http://lilypond.org/doc/v2.17/Documentation/learning/types-of-properties)
for examples of the second. Is one form preferred over the other? If so,
maybe that should be consistently used throughout the documentation.

Nick
