How to Count Tuplets That Contain Mixed Note Values

A tuplet defines a division into equal duration units. An eighth-note triplet, for example, divides one quarter-note duration into three equal units. Those units can then be combined or subdivided to make a mixed rhythm. The MuseScore Studio Handbook’s “Tuplets” page explains this equal-unit foundation.

The practical distinction is between duration units and attacks, the moments when you start notes. A quarter note followed by an eighth note can fill an eighth-note triplet: the quarter takes two eighth-note units, and the eighth takes one. You play two attacks while counting three underlying units.

A ratio supplies another part of the instruction. With the same reference note value on both sides, 3:2 means three units occupy the time normally taken by two; 5:4 means five occupy the time of four. The reference value matters: three eighths in the time of two eighths occupy one quarter note, while three quarters in the time of two quarters occupy two quarter notes. Steinberg’s Dorico SE 6.2 “Tuplets popover” documentation specifies both the ratio and its reference duration.

Use this sequence before trying to play the rhythm:

1. Identify where the tuplet begins and ends.
2. Establish its ratio, reference note value, and total duration.
3. Choose a small written value that divides every note and rest into whole units.
4. Convert each duration into that unit and add the results.
5. Space the resulting grid evenly across the group’s total duration.
6. Mark the grid positions where notes begin.

For the non-nested examples here, sixteenth-note units give these conversions. These are relationships between the written values inside the tuplet, before applying its timing ratio:

Written value	Sixteenth-note units
Sixteenth note	1
Eighth note	2
Dotted eighth note	3
Quarter note	4

Choose the grid for the actual rhythm. A quarter-plus-eighth triplet needs only three eighth-note units. If a sixteenth appears within that same triplet span, divide each of those three units in half, giving six smaller units.

This grid is an analytical method derived from proportional duration scaling. LilyPond’s “Writing rhythms” notation reference documents applying a tuplet factor to a musical expression. Consequently, within one non-nested tuplet, the written duration relationships remain proportional: an eighth still lasts twice as long as a sixteenth.

For this illustrative example, assume a 3:2 eighth-note triplet occupying beat 1 of a 4/4 measure. Inside the group, the written rhythm is a quarter note followed by an eighth note.

Use three equal subdivisions across the beat:

Subdivision	1	2	3	Next beat
Count aloud	ONE	two	THREE	TWO
Play	Start quarter	Continue quarter	Start eighth	Start next beat

Say “one, two, three” evenly between the beginning of beat 1 and the beginning of beat 2. Start the quarter note on subdivision 1, sustain it through subdivision 2, and start the eighth on subdivision 3.

The two notes last two-thirds of a quarter-note beat and one-third of a quarter-note beat. You can verify the total: 2/3 + 1/3 = 1 beat. The second attack therefore falls later than the halfway point.

Reverse the written order and the count changes. For an eighth followed by a quarter, attack on subdivisions 1 and 2, then sustain through subdivision 3. Both versions fill the same beat, but their attack positions differ.

Keep the same one-beat, 3:2 eighth-note triplet span. Now use this illustrative written sequence: eighth, sixteenth, sixteenth, eighth. In sixteenth-note units, its lengths are 2 + 1 + 1 + 2 = 6.

Divide the beat into six equal small units. You can say “one-and, two-and, three-and,” with each syllable occupying one unit:

Grid position	1	2	3	4	5	6
Spoken count	one	and	two	and	three	and
Action	Attack	Continue	Attack	Attack	Attack	Continue

The attack positions are 1, 3, 4, and 5. Count all six positions evenly, including the two where you continue a note. At the next grid position after 6, the following quarter-note beat begins.

Here the smaller grid units each last one-sixth of a quarter-note beat. The eighth notes each occupy two units, or one-third of a beat; the sixteenths each occupy one unit. This is a triplet group with four attacks because one of its three underlying eighth-note units has been split in half.

As a practice step, first tap all six units. Then tap only positions 1, 3, 4, and 5 while continuing to speak the whole grid. Finally, play the written durations, sustaining each eighth through its second unit.

For another illustrative one-beat eighth-note triplet, use dotted eighth, sixteenth, eighth. Convert it to sixteenth-note units: 3 + 1 + 2 = 6. On the same six-position grid, start notes at 1, 4, and 5.

Hold the first note through positions 1–3, play the short note at 4, and start the final note at 5, sustaining through 6. The durations are 1/2, 1/6, and 1/3 of a quarter-note beat. Their sum is one beat. In this particular example, the dotted eighth ends exactly halfway through the beat.

A useful way to locate every attack is to add the preceding durations, then add 1. For lengths 3, 1, and 2, the first start is 1; the second is 3 + 1 = 4; the third is 3 + 1 + 1 = 5. This avoids placing notes by visual spacing.

Rests occupy grid time without a sounding note. In the six-position eighth–sixteenth–sixteenth–eighth example, replace the first sixteenth with a sixteenth rest: position 3 becomes silent, while the remaining attacks stay at 1, 4, and 5. Keep counting through the rest.

Ties join durations into a sustained note. LilyPond’s “Writing rhythms” reference, under “Ties,” explains that a tie extends a note’s duration. For counting, retain every underlying unit but omit a new attack at the tied continuation. If a tie crosses the tuplet boundary, calculate each portion using the timing that applies on its own side.

Consider an illustrative 5:4 sixteenth-note quintuplet occupying one quarter-note beat. Its written rhythm is eighth, sixteenth, eighth. Counting in sixteenth-note units gives 2 + 1 + 2 = 5.

Count five equally spaced positions across the beat:

Grid position	1	2	3	4	5
Action	Attack	Continue	Attack	Attack	Continue

Start the notes on 1, 3, and 4. Their durations are 2/5, 1/5, and 2/5 of a beat. Start the following beat immediately after position 5 has lasted its full unit.

Practice five equal taps first, then keep only the required attacks. Avoid letting the three sounding notes become equally spaced: the written durations call for a long–short–long pattern.

Check the specified ratio before using this example elsewhere. Steinberg’s tuplet ratio table includes both 5:2 and 5:4 quintuplets. A printed 5 therefore needs its rhythmic context; it does not establish the total span by itself.

Use two checks. First, add the written units: do they fill the intended group? Second, apply the timing ratio. For a non-nested n:m tuplet using the same reference value on both sides:

Actual duration = ordinary written duration × m/n

For the quarter-plus-eighth 3:2 example, measure ordinary written durations in quarter-note beats: (1 + 1/2) × 2/3 = 1. For the eighth–sixteenth–eighth 5:4 example: (1/2 + 1/4 + 1/2) × 4/5 = 1. These calculations confirm the span; the grid identifies the individual attacks.

If the arithmetic fails, recheck the bracket’s extent, dots, rests, reference value, and any inner tuplet. Nested tuplets require another timing layer: an inner group divides a duration already belonging to the outer group. Both the MuseScore Studio Handbook and LilyPond’s notation reference document nested tuplets. Work out the outer span first, then resolve the inner group within its allotted time.

Once the grid is clear, practice with a metronome marking the surrounding quarter-note beats. Speak every subdivision, add the required attacks, then play one beat before and one beat after the tuplet. Check that the following beat arrives on the click without shortening the final note.

When you return to the passage, identify the group’s span, convert its durations into equal units, and mark the starts. Keep the grid moving through sustained notes and rests. That gives you a precise count for the written rhythm and a clear place to rejoin the surrounding pulse.
