Music: Rhythm Fractions and Time Signatures

Counting beats with notes, rests, and measures

Music - Grade 4-5

Instructions: Read each problem carefully. Count the beats in each measure and show your work in the space provided.
  1. 1

    In 4/4 time, a whole note lasts 4 beats. What fraction of a whole note is one quarter note?

    Think about the word quarter, which means one out of four equal parts.

    One quarter note is 1/4 of a whole note because four quarter notes equal one whole note.
  2. 2

    In 4/4 time, a half note lasts 2 beats. What fraction of a 4-beat measure does one half note fill?

    One half note fills 2/4 of the measure, which is equal to 1/2 of the measure.
  3. 3

    A measure in 4/4 time has one quarter note, one quarter rest, and one half note. How many beats are in the measure?

    Add the beat values: 1 + 1 + 2.

    The measure has 4 beats because the quarter note is 1 beat, the quarter rest is 1 beat, and the half note is 2 beats.
  4. 4

    In 3/4 time, how many quarter-note beats are in each measure?

    There are 3 quarter-note beats in each measure of 3/4 time.
  5. 5

    In 2/4 time, a measure has two quarter notes. Is the measure complete? Explain your answer.

    Look at the top number of the time signature.

    Yes, the measure is complete because 2/4 time needs 2 quarter-note beats, and two quarter notes make 2 beats.
  6. 6

    In 4/4 time, which rhythm fills exactly one measure: A) four quarter notes, B) three quarter notes, or C) five quarter notes?

    A) four quarter notes fills exactly one measure because 4/4 time needs 4 quarter-note beats.
  7. 7

    In 4/4 time, two eighth notes equal one quarter note. What fraction of a whole note is one eighth note?

    A whole note has 4 beats, and an eighth note has 1/2 beat.

    One eighth note is 1/8 of a whole note because eight eighth notes equal one whole note.
  8. 8

    In 4/4 time, a measure has four eighth notes and one half note. How many beats are in the measure?

    The measure has 4 beats because four eighth notes equal 2 beats and one half note equals 2 beats.
  9. 9

    In 3/4 time, a measure has one half note and one quarter note. Is the measure complete? Explain your answer.

    A measure in 3/4 time needs 3 beats.

    Yes, the measure is complete because the half note is 2 beats and the quarter note is 1 beat, for a total of 3 beats.
  10. 10

    In 4/4 time, write the missing number of beats: one dotted half note equals 3 beats, so it fills ___/4 of a measure.

    A dotted half note fills 3/4 of a measure because it lasts 3 beats out of the 4 beats in 4/4 time.
  11. 11

    In 4/4 time, a measure has one quarter note and one half note. How many more beats are needed to complete the measure?

    A complete 4/4 measure has 4 beats.

    One more beat is needed because the quarter note is 1 beat and the half note is 2 beats, making 3 beats so far.
  12. 12

    The bottom number in 4/4 time is 4. What kind of note gets one beat?

    The quarter note gets one beat because the bottom number 4 means the beat is counted in quarter notes.
  13. 13

    In 6/8 time, the top number 6 means there are 6 eighth-note beats in each measure. How many eighth notes fill one measure?

    Use the top number to count how many beats are in each measure.

    Six eighth notes fill one measure in 6/8 time because the top number tells how many eighth-note beats are in the measure.
  14. 14

    In 4/4 time, compare these note values: one half note or two quarter notes. Which lasts longer, or are they equal?

    They are equal because one half note lasts 2 beats and two quarter notes also last 2 beats.
  15. 15

    Create one complete measure in 4/4 time using at least two different note or rest values. Write the beat values and explain why your measure is complete.

    Your total must add to 4 beats.

    One possible answer is one half note, one quarter note, and one quarter rest. This is complete because 2 + 1 + 1 = 4 beats.
