# 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.

You will then have a 1.5 beat duplet.

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).

Could it be that the printed notation is incorrect and it should in fact be a quadruplet instead of a duplet? Would not surprise me, I've found many mistakes with printed versions of Frank Zappa's music.

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.
