Melodies Play Together

Aim: How does the melody change when played in harmony or with accompaniment?
Summary: We explore the difference between melodies in unison and melodies played in harmony.
Standards: National 1, 4, 7, 8; NYC 1, 2, 3, 5
Vocabulary: harmony, unison

Exploring Unison and Harmony


  • Have the class sing a pattern of notes together.
  • Example: Do, Re, Mi, Re, Do.
    • When we all sing the same notes together at the same time, it is called singing in unison.


  • Divide the class into two groups or work with two students at a time.
  • Begin by assigning each group a pitch from the major scale. Have the groups practice singing their pitches with a simple rhythmic pattern.
  • Example: Group 1 sings Do, Do, Do (unison). Group 2 sings Mi, Mi, Mi (unison).
  • You may use solfège, note names, or scale degrees.
  • Next, have each group sing its assigned pitch pattern simultaneously (harmony).
  • Have the groups trade pitches so that they each get a turn singing the root of the interval.
    • When two or more people sing multiple pitches together at the same time, it is called singing in harmony.
  • Experiment with different combinations from the major scale. See the table below for examples.
    • Which combinations are your favorite? Why?
    • Which combinations are your least favorite? Why?

Group 2 Sings:

High Do

Harmonic Interval:

Try extending some of the harmonic patterns we learned in this activity by moving the phrases up or down the scale.

Exploring Unison and Harmony in “Oye”

  • “Oye” includes an optional two-part harmony. Once your students are familiar with the melody, you can explore having some of your students sing the lower part.
  • Listen to Track 22.
    • Raise your hand when you think you hear the singers singing in harmony. Lower your hand when you hear them singing in unison.
  • Refer to the interactive sheet music for “Oye.”  (You may wish to have the students use their print-outs of the “Oye” Sheet Music (PDF) to highlight the melodic line in one color and the harmonic line in a different color to make it easier to follow).
    • Note when the melody is sung in unison (one note at a time) and when there is harmony (two notes at a time).
    • We have already explored some harmonic intervals. This song uses thirds, fourths, and fifths to create the harmony.
  • Play Track 24. Follow along with the interactive sheet music for “Oye.”
    • Notice how each line is moving (by steps or staying on the same note).
    • When does the harmonic line move in the same direction as the melodic line? When does it do something different than the melodic line?
  • As a group, practice singing the harmonic line along with Track 24.
  • Once the group is confident singing the harmonic line, split the class into two groups and sing the melody and harmony together with Track 25.
