The 6th graders just completed one of my favorite units, Invented Instruments. We spent at least 3-4 weeks working on this project.
First, we discussed the 4 different ways we can classify instruments based on the way they make sound: aerophones (air vibrates), chordophones (a string vibrates), idiophones (solid matter vibrates), and membranophones (a stretched skin vibrates).
Then, we researched different instruments that we could make using common household items such as cans, string, paint, or wood. We spent a class in the computer lab looking up ideas for homemade instruments. Once they had decided on what to make, the students had to classify it as either a chordophone, aerophone, idiophone, or membranophone. They also had to make sure that their instrument made at least 3 different sounds and could play both loud and soft dynamic levels. All instruments needed to be decorated and finished looking.
One week was spent building the instruments (in class or at home) and then the next week was spent composing a sound piece that would be performed on the instrument. The sound piece had to last between 20-40 seconds and would be performed in front of the class. We used numbers, letters, or symbols to notate our pieces.
Here are some pictures of what the students created. You'll be amazed at how creative some of them were!
