In order to test the understandings gained in your investigation, you should compose a creation of your own that demonstrates the insights that you have discovered. Because music is in the end "understood" aurally, your creation should involve sound, not simply a text-based report or critique. Your creation can be large or small, and it may be completely original or include borrowed musical ideas. For example, it might be composing the harmony for a song that you are writing, an arrangement of a favorite tune, or a short etude that would help you practice performing a certain type of harmony.
- If you discovered that certain types of chords are used in your favorite jazz piece, jazz up a favorite non-jazz piece by re-writing it using those types of chords.
- If you discovered that your favorite composer uses a particular progression in modulations, compose a piece that uses that progression to modulate to a new key.
- If you discovered that an "eerie" atmosphere was created by using certain chord voicings in a piece, write a short "eerie" piece of your own using similar voicings.
