Both examples contain six even eighth notes. Listen for the stronger attacks: 6/8 groups them 3 + 3, while 3/4 groups them 2 + 2 + 2. Count the groups rather than the individual notes.
A · Worked example
Three groups of two (3/4)
Listen to six equal eighth notes. Accents every three eighths create two larger beats; accents every two eighths create three larger beats.
The stronger attacks fall every two eighth notes: ONE and TWO and THREE and. These are three quarter-note beats in 3/4.
B · Compare the difference
Two groups of three (6/8)
Compare 3 + 3 with 2 + 2 + 2. The eighth-note spacing stays the same while the number of larger beats changes.
The stronger attacks fall every three eighth notes: ONE two three FOUR five six. These are two dotted-quarter beats in 6/8.
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: Duple refers to groups of two beats; triple refers to groups of three.
1 · Guided practice
Say “ONE la li TWO la li” for 6/8 or “ONE and TWO and THREE and” for 3/4 before choosing.
2 · Independent practice
Classify each accent cycle from more than one repetition. Do not infer grouping from how many seconds the excerpt lasts.
3 · New-question check
Count the accent cycle in two new excerpts without carrying the previous grouping forward.
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.
Every sound is heard as an accented start. Establish an even pulse before tracking accents. Steady Beat
Three subdivisions are mistaken for three main beats. Revisit simple triple and compound duple grouping. Triple Meter
