The most serious thing you’re doing wrong is not submitting an MWE to
illustrate your problem, e.g.:
\version “2.18.2”
{ \time 3/4 r1 | r1 }
The next most serious thing you’re doing wrong is not reading the
documentation, e,g, since you’re having a problem with rests, section 1.2.2
“Writing Rests” of the Notation RM has a subsection called “Full Measure
Rests”. So the way to fix your problem is to write:
\version “2.18.2”
{ \time 3/4 R2. | R2. }
(You might also upgrade to version 2.19.83, which is very stable and fixes a
lot of problem that existed in version 2.18.2)___

This is natural because an "r1" *is* a whole note rest taking four beats. What you want to have is a full note rest that *looks* like an r1 but is actually written with a capital "R" and the actual duration. So what you need is R2. You'll also notice that this one will (correctly) be centered in the measure while the "r1" will sit at the left.

More like R2.
What is the difference between R2. and R1*3/4 apart from the obvious difference
in the source file?
It’s “half with dot” vs. “whole scaled by 3/4” even in the internal
structure which you can show with displayMusic:
\displayMusic {
\time 3/4
R2.
R1*3/4
R4*3
}
LilyPond’s Duration type makes this distinction, Moment doesn’t:
#(display (ly:duration-length #{ 2. #}))
#(display (ly:duration-length #{ 1*3/4 #}))
#(display (ly:duration-length #{ 4*3 #}))
For the output of MultiMeasureRests it doesn’t make a difference, for
Rests and NoteHeads the choice of the duration affects the glyph choice.

Probably none. I think that R only looks at the actual time spent and doesn't care just how the time is spent. But if the next note is, say, c' then a default duration of 2. and a default duration of 1*3/4 will make it look different. -- David Kastrup ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

Correct, but I don’t agree with: It is up to you to decide which you want There are debatable conventions in notation but it’s a hard rule to use centered whole rest symbols for full measure rests—according to Gould only in complicated music from the 20th century (complicated rhythms paired with many time signature changes) you might deviate from that rule. ___ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user

Re: Puzzled about r1 issue in 3/4 time
Hi Michael, some further clarification: On 23.10.19 23:09, Carl Sorensen wrote: R1*3/4 or R2. is a whole measure rest in ¾ time. With normal rests (as with notes) the glyph, or symbol, that is printed depends on the main duration you enter, ignoring the scaling factor. These three all look the same: r4 r4*10 r4*3/4 With multi-measure rests the appearance will be automatically determined based solely on the ‘total’ duration and the number of bars it encompasses. Thus these three mean, and look, exactly the same: R2. R1*3/4 R4*3 As you have identified, you can use “r2.” to get a ¾ note rest. This rest will appear in the same note column as the first quarter note in the measure. You can also use “R1*3/4” or “R2.” in ¾ time to get a ¾ note (whole measure) rest. This rest will appear centered in the measure. It is up to you to decide which you want. Here I have to say that it’s not really up to you. There is a clear typographical rule that a rest that fills a whole measure has to be centered. Thus using \time 3/4 r2. is wrong and will look weird to anybody with experience in good musical notation. Even if that mistake is often made and found in published scores… it doesn’t make it any less of a mistake.

I have ended the music for “Silver Bells” into lilypond, and I am seeing a puzzling error. The song is in 3/4 time, but the rest in measure 33 seems to betaking 4 beats - I get a bar check failed and there are one two rests in measure 34, and an extra measure is inserted at the end. What am I doing wrong? r1 is a whole-note (4/4) rest. R1*3/4 or R2. is a whole measure rest in ¾ time. As you have identified, you can use “r2.” to get a ¾ note rest.

This rest will appear centered in the measure. It is up to you to decide which you want. At any rate, Lilypond has no rest that takes as an argument the number of measures the rest should occupy. All rests, whether whole measure or regular, take as an argument the musical duration of the rest.

What am I doing wrong? “r1” means a whole (=4/4) rest, not a whole measure rest. The offending r1 is on the 3rd line of the first branch of the alternative below - and if I change that r1 to “r4 r4 r4”, or to “r2.”, the issue goes away. Yes, “r2.” has the correct length. But you probably wanted to follow the engraving rule (as you should) and have a whole rest *symbol*. For that you have to tell LilyPond that it’s a *full measure* rest by using a capital R: “R2.” LilyPond will then use the correct symbol and center it horizontally.
