Supplied materials

  • Paper and a pencil, or typed notes. Write complete bars and mark their quarter-note beat positions.
  • Example: In this Western simple-meter exercise, 2/4 supplies two quarter-note beats per complete bar. How many beats occupy four complete bars? Choices: (A) 10 beats (B) 7 beats (C) 8 beats (D) 9 beats.
  • Try this: In this Western notation exercise, 3/4 gives 3 quarter-note beats per complete bar. How many quarter-note beats fill 3 bars? Choices: (A) 10 beats (B) 11 beats (C) 8 beats (D) 9 beats.

Learn the idea

In these simple-meter examples, the top number tells how many quarter-note beats fill a complete bar. The bottom number 4 names the quarter-note beat unit. Multiply the beats in one bar by the number of complete bars.

Look at the example. Each complete bar contains two quarter-note beat positions. Four bars therefore require 2×4=8 positions. The denominator four supplies the quarter-note unit here; incomplete bars and other meter interpretations would need their stated conditions.

These questions use complete bars in simple meter. A different meter or an incomplete bar needs its own stated beat plan.

  1. Read the 2/4 example. Find the number of beats in each complete bar and the number of bars.
  2. Use 2 × 4 to compare eight beats with another answer. Explain why four two-beat bars need eight beats.
  3. Try the check question and the three practice questions. Then read the feedback.
  4. Write three complete bars of three quarter-note beats and total their pulse positions.
  5. Check your work. Each bar contains three beats, and the three-bar plan contains nine quarter-note beats.
Worked example

See the method in action

In this Western simple-meter exercise, 2/4 supplies two quarter-note beats per complete bar. How many beats occupy four complete bars? Choices: (A) 10 beats (B) 7 beats (C) 8 beats (D) 9 beats. Answer: 8 beats. Each complete bar contains two quarter-note beat positions. Four bars therefore require 2×4=8 positions. The denominator four supplies the quarter-note unit here; incomplete bars and other meter interpretations would need their stated conditions.

Helpful tips
  • In the supplied simple-meter examples, the top number counts quarter-note beats per complete bar and the bottom four names the quarter-note beat unit.
  • The exercise supplies complete bars in simple meter.
In this Western notation exercise, 3/4 gives 3 quarter-note beats per complete bar. How many quarter-note beats fill 3 bars?

Feedback appears here after you check. This is practice, not a graded school assessment.

9 beats

Each bar contains 3 quarter-note beats. Multiply by 3 complete bars: 3×3=9. The top number counts beats here; the bottom four names the quarter-note beat unit.

Take it further

Try a new example: In the supplied Western simple-meter model, 4/4 has four quarter-note beats per complete bar. How many beats fill five complete bars? Choices: (A) 19 beats (B) 20 beats (C) 21 beats (D) 22 beats. Answer: 20 beats. Five complete bars each contain four quarter-note beat positions. Multiply 5×4=20. This counts the whole supplied duration; a pickup bar or another meter would need its own stated interpretation. Make your own: Write three complete bars of three quarter-note beats and total their pulse positions. Check your work: Each bar contains three beats, and the three-bar plan contains nine quarter-note beats.
