A dotted quarter is 1.5 quarter-note beats; an eighth is 0.5. The pair fills two beats in a 3:1 ratio.
A · Worked example
Pattern A · attacks at 1, 2.5, 3, 4 in quarter-note units
Divide the dotted-quarter/eighth pair into four equal eighth-note slots. The long note occupies three slots and the short note one.
Count 4/4 at 80 BPM. Attacks occur at 1, 2.5, 3, 4 in quarter-note beat units. Rests take time without an attack.
B · Compare the difference
Pattern A · attacks at 1, 2, 3, 4.5 in quarter-note units
Listen for long–short versus short–long placement. A 3:1 division differs from both two equal notes and three equal triplet parts.
Count 4/4 at 80 BPM. Attacks occur at 1, 2, 3, 4.5 in quarter-note beat units. Rests take time without an attack.
Blocks show durations in quarter-note units. R marks a rest; > marks an accented attack. Numbers below each bar are quarter-note positions, which differ from the main beat in 6/8.
Check the idea: The pair totals two quarter-note beats: 1.5 plus 0.5.
1 · Guided practice
Speak “1 and 2 and” across the two-beat pair. Identify the attack on the final “and” before selecting.
2 · Independent practice
Choose the complete bar; do not label every unequal pair as the same pattern. Check whether the dotted pair comes first or last.
3 · New-question check
On new questions, count the short-first version from its first attack without silently swapping the two durations.
Each session starts with two guided questions, then your chosen practice set, followed by two new questions at a different tempo. First answers, same-question retries, and the final check have separate results.

Dotted pairs sound like triplets. Compare three equal parts with straight subdivisions. Straight or Triplet
