Task

Use what you're learning to complete the Noteflight task below, then check your own work before moving on.

Inquiry: How does changing the meter of the same musical idea change how it feels?

Reflect: What did “Measures & Meter” teach you about your own composing choices?

Key words

Words you will use today

Meter
The repeating pattern of strong and weak beats that groups music into measures.
Time signature
The two numbers at the start of the music. The top number is how many beats each measure has; the bottom number is the note value that gets one beat (4 means a quarter note).
Strong / weak beats
Beat 1, the downbeat, is the strongest beat in every meter. In 4/4, beat 3 is moderately strong and beats 2 and 4 are weak. In 3/4, beats 2 and 3 are both weak.
4/4
Four quarter-note beats per measure, felt strong–weak–medium–weak.
3/4
Three quarter-note beats per measure, felt strong–weak–weak.
Reading the time signature
Target 1

The time signature tells you how to count

Every example so far has started with 4/4. That pair of numbers is the time signature. The top number tells you how many beats are in each measure; the bottom number tells you which note value gets one beat. A bottom 4 means the quarter note gets the beat. So 4/4 means four quarter-note beats per measure, and 3/4 means three. The note values themselves do not change: a quarter note is still one beat and a half note is still two. What changes is how many beats fit before the next bar line, which is why the count starts over at 1 after three beats in 3/4.

01

4/4: count 1 2 3 4

Four beats per measure. “Ode to Joy” fills each measure with four quarter notes, one per beat, until the dotted rhythm in its last measure.

Beethoven, “Ode to Joy,” mm. 1–2, counted.
02

3/4: count 1 2 3

Three beats per measure. This tune, sung as “America” in the United States and as “God Save the King” in Britain, counts 1 2 3 in every measure. Measure 2 uses the dotted quarter and eighth you learned in Lesson 1: 1 (2) + 3.

“America” (traditional), mm. 1–2, in C, counted.
Checking measures
Target 2Target 1

Every measure must add up to the top number

To check a measure, add the beat values of every note and rest in it and compare the total with the top number of the time signature. The usual mistakes are an extra or missing beat, forgetting that a dot adds half a note’s value, and carrying a 4/4 habit into 3/4: a whole note (4 beats) cannot fit in a measure of 3/4, so a note that fills a 3/4 measure is a dotted half. (One exception you will see in printed music: a completely silent measure is marked with a whole rest in any meter.)

01

Adding up measures of 3/4

Write the value of each note under it and add. Measure 1: 1½ + ½ + 1 = 3. Measure 2: a dotted half note, 3 beats on its own. Both match the top number, 3.

“America,” m. 4 and the final measure, with beat values.
02

Spot the incomplete measures

This draft is meant to be in 3/4. Measures 1 and 3 add up to 3 beats. Measure 2 (orange) holds 4 beats, a 4/4 habit, and measure 4 (orange) holds only 2½: a half note plus an eighth rest leaves half a beat unaccounted for.

Course example with errors: mm. 2 and 4 (orange) do not add up to 3.
Hearing meter
Target 3

Meter changes how music feels

Meter is not only a counting system; it is something listeners feel. In 4/4, beats group strong–weak–medium–weak, an even, two-by-two pattern heard in marches, hymns, and most popular songs. In 3/4, beats group strong–weak–weak, which gives a lilting, circular feel heard in waltzes and minuets. In the examples below, the lower staff plays a low note on every downbeat and lighter, higher notes on the other beats, so you can hear where each measure begins. (Playback does not accent beats, so listen for the low notes.)

01

Four beats: steady and even

Count along with the low notes. Every fourth beat the bass drops down, and “Ode to Joy” moves forward in even, balanced steps.

Beethoven, “Ode to Joy” (in C). Lower staff: low note on each downbeat (added).
02

Three beats: lilting and circular

Now the bass drops every third beat. The strong–weak–weak pattern makes “America” sway, and its longest notes, the dotted quarters and the final dotted half, all start on a downbeat.

“America” / “God Save the King” (traditional), in C. Lower staff added.
Worked comparison
Target 1Target 2Target 3

One idea in two meters

Here is a short course example written in 4/4, then rewritten in 3/4. The pitches and their order stay the same. To fit three beats per measure, the durations have to change, and that changes which notes land on the downbeats. Play both and listen to the difference.

01

The idea in 4/4

Short–short–long in each measure: two quarter notes lead to a half note on beat 3.

Course example in 4/4 (2 measures). Lower staff added.
02

The same idea in 3/4

Long–short, then a note that fills the whole measure. Every downbeat now carries a held note.

The same pitches in 3/4 (4 measures). Lower staff added.
Feature4/4 version3/4 version

Rhythm patternShort–short–longLong–short, then one note per measure
On the downbeatsC, FC, G, F, C (each held)
FeelWalks steadily toward each half noteSways; each held note fills its measure

Model description: Both versions use the same six pitches in the same order. In 4/4, each measure moves short–short–long: two quarter notes lead to a half note on beat 3, so the idea walks steadily toward its held notes. To fit 3/4, the rhythm becomes long–short followed by a full-measure dotted half: C now lasts two beats on the downbeat, and G and the final C each fill an entire measure. Every downbeat now carries a held note, and the strong–weak–weak grouping makes the idea sway like a waltz instead of moving forward evenly. Every 4/4 measure adds up to 4 beats and every 3/4 measure to 3.

Notice what the comparison does: it confirms each measure adds up, names what changed in the rhythm, identifies which notes land on the downbeats, and describes the effect on the feel. Your Noteflight comparison should do the same.

6Which statement best explains why the 3/4 version of the idea feels different from the 4/4 version?

Target 3
Take it to Noteflight

One idea, two meters

Write a short idea in 4/4, then rewrite it in 3/4 the way the worked comparison does: same pitches, same order, new durations. Then listen to how the meter changes its feel.

Your Noteflight task

Write the same short idea once in 4/4 and once in 3/4. Play both and compare.

1Your two versions

Version 1Target 1
Write it in 4/4

A 2–4 measure idea. Every measure adds up to 4 beats.

For example
Course example in 4/4
Version 2Target 2
Rewrite it in 3/4

Same pitches in the same order. Change durations so every measure adds up to 3 beats.

For example
The same idea in 3/4
DownbeatsTarget 3
Choose the downbeats

Decide which notes should land on beat 1 in each meter. Held notes on downbeats make the meter easy to feel.

For example
“America,” mm. 2–3

2While you build

Target 1

Confirm each version begins with the correct time signature: 4/4 for Version 1, 3/4 for Version 2.

Target 2

Write the beat value under every note and add each measure. Fix any measure that does not match the top number.

Target 3

Play both versions. Write 2–3 sentences, modeled on the worked comparison, naming what changed in the rhythm, what lands on the downbeats, and how each version feels.
