Off Notation Input Issue

Anyone know how I can enter the duplets in the image? They appear to be a 2:1.5 ratios but I can’t figure out any way to do this.

Hi mike320 and thanks for your reply, I should have stated that I already tried that. When I do that, the duplet I get is two 8th notes rather than 2 quarter notes (first duplet in the printed score is two eighth notes and a quarter note in the space of a dotted quarter note).

The printed score is what I would expect and I advised you without trying it out myself.

In my opinion it should be easy to do, but I see no way to get a duplet quarter note out of a dotted quarter note in 12/8 time. I have used some simple workarounds in similar cases, but they did not work. I could come up with a couple complex workarounds, but I would suggest you treat it as a misprint in the score and halve the durations of the duplets. That is, I would make the quarter notes eighth notes and eighth notes sixteenth notes. Musicians will understand what is expected in either case. If I ever run into a duplet in x/8 time I examine the measures to assure I understand the intent.

You can match the original notation by:

  1. creating 4:3 tuplet
  2. nesting 2:2 tuplet inside
  3. setting the 4:3 bracket and numerals not to display

The lower staff shows both tuplets.

Is this correct musically, though? A dotted crotchet in 12/8 contains 3 quavers. Making a doublet/duplet implies 2 in the space of 3 and this would be 2 quavers in the space of 3. To get 2 quavers plus a crotchet, as shown in the example, you would properly need 4 in the space of 3.

I've seen both notations from many different eras though I'm not familiar with the piece the OP used to start the conversation. There seems to be a lot of uncertainty in how a duplet on a dotted crotchet is to be written, and that's why I would always look closely at a measure written in x/8 with any tuplet actually. I've seen many tuplets in all time signatures where the number of notes is either halved or doubled. When I'm transcribing these, my practice is to make them look the same if possible. When it's not possible, I use my knowledge of music and make the best possible representation that will make the playback correct and convey to musicians what is expected. It seems to me there should be some ratio that would give you a crotchet duplet in this situation, but I can't find it in MuseScore.

The more I think about it, I would tend to agree that underquark's assertion that a duplet on a dotted crotchet should be two quavers and I have actually written it this way in my own original music.
