For the past few weeks, students in second through fifth grade have been learning about a special type of musical texture called harmony. There are many ways to create harmony, such as melodic ostinatos, rounds, partner songs, and chords. This week, students in fourth and fifth grade learned how combining two different songs at the same time can create harmony in the form of partner songs. The students sang two familiar songs, "Hot Cross Buns" and "Bow Wow Wow," together at the same time. Then, after labeling the pitches with letter names, the students had a choice of which song to play on the xylophones, metallophones, and glockenspiels. Listen as Tuesday's fourth grade class, B2, plays these two songs together.
