Quadruplets in compound time

• Jul 17, 2015 - 09:14

Im in 12/8 time. The first three notes of the bar are 3 quavers making up the first beat. I trying to write 4 dotted crotchets in the space of 3 for the rest of the bar as a quadruplet. If I select from Notes menu "Tuplets" all I get is quavers grouped as fours. Any one know how to do this?

The only thing I can think of is writing the bar as 15/8 for that extra beat. Any idea how to do that?

The reasons you are seeing quavers is that when creating tuplets, you need to start by selecting the total value of the tuplet. So, for instance, if you want four notes in the space of a dotted minim, you you first select the minim, then enter the quadruplet.

What you are describing won't be possible, though, since there is no single note value that you could select that would represent "the rest of the bar". And I think for the same reason, human musicians reading the score would struggle to. I would say you would be better off finding another way to represent that rhythm, but I can't think of one!

So the workaround of using a 15/8 bar seems as good as any. Just right click the bar, Measure Properties, and change the "actual duration". The ou can manully add a bracket, I guess.

Maybe someone else will have a better idea?

Clever idea! Copy/paste worked for me, maybe it depends what beat positions you are trying.

But how about this:

1) enter the first three quavers in 12/8 normally
2) click the first rest after that
3) Edit / Measure / Split Measure
4) select the measure rest in the newly-created measure, which has an "actual" duration of 9/8
5) Notes / Tuplets / Other
6) 4 / 3, OK
7) enter the four dotted quarters
8) select the two measures
9) Edit / Measure / Join Measures

A bit convoluted, but it works!

It *is* simple, but maybe non-obvious. You want four dotted quarters in the amount of time that would normally take three dotted quarters. That's 4/3. You could just as easily think of it as twelve eighths in the time normally taken by nine, so 12/9. But that reduces to the same thing.

It's kind of an odd glitch that MuseScore won't actually enter the dotted note value for you. It won't ever created a dotted note value by default. So instead of four dotted quarters, it gives you three halves, which is the same thing actually. It just as easily could have chosen to give you the twelve eighths. But either way, you can enter the dotted quarters once you have it set up.

So the trick here is to do a good job of visualizing the result - how many notes of a certain duration type you want in the space of a different number number of notes of that same duration type. From there it is just a matter of entering those two numbers into the boxes.
