# Is this grouping with duplets correct for 6/4?

Very sorry for bad photo quality, but I hope the notes are visible. Here, have I done anything wrong with the grouping?!

• Can you tell us what kind of rhythm is intended in the first measure? How many beats are the first two notes meant to occupy, and on (or during) which beat of the measure does the long note start? Otherwise, all we can say is "Yes, something is wrong in the first measure." Sep 21, 2021 at 15:34
• Is the first measure perhaps meant to be just like the second, but backwards, and with a rest taken out of the long note? Sep 21, 2021 at 15:35

The second measure is fine, but the first one is wrong. The general rule is that your notes should never cross the "major beats" of the bar. In 6/4, the "major beats" are two dotted half notes, and so the double-dotted half note that crosses this boundary is needlessly confusing.

Instead, use ties to "restart" the note at the beginning of the second beat while indicating that it is to be held:

``````X:1
M:6/4
K:C
L:1/8
(2 FF z F2- F4- F z | F6 (2 F2 F2
``````

The initial duplet in this version also has the advantage that it crosses two "minor" beats (the quarter-note subdivisions of the dotted half-note "major" beats.) I would personally find the following easier to interpret:

``````X:1
M:6/4
K:C
L:1/8
F>F- F z F2- F4- F z | F6 (2 F2 F2
``````

This is equivalent to the first version but also more clearly shows the subdivision of the first dotted half-note. (The quarter-note duplet also obscures the subdivisions in the same way, but it is easier to interpret since it takes up the entirety of a "major" beat, so I'd be inclined to leave it as it is.)

• I agree that the first measure is wrong, but I think the reconstructive surgery went awry. I'm guessing the OP simply intended ordinary 8th notes, and was mistakenly under the impression that the "2" marking was necessary. I'm guessing what was intended was two ordinary 8th notes (taking up beat 1), an 8th rest, and then a tied note occupying all the rest of the bar except for a final 8th rest. Without confirmation, impossible to say more than "Yes, something is wrong in that first measure." Sep 21, 2021 at 15:30
• @AndyBonner: Fair point. I assumed that since the given notes added up to the right amount of time, that the note lengths were written as intended. But I suppose that it's possible that things went even more wrong than I assumed. :-) Sep 21, 2021 at 15:34
• I came up with the same notation for the first measure as this answer. If the first two eighths are ordinary followed by eighth rest, double dotted half, then eighth rest... then there is one more eighth note value remaining. Sep 21, 2021 at 15:48
• For some reason when people add music notation in this way I sometimes get a very random series of beamed 8th notes followed by a dotted half which has nothing to do with the question. Any thoughts? Sep 21, 2021 at 16:58
