The materials that were used to construct the pyramid by I.M. Pei was steel and glass. I'm sorry if it wasnt much help but that's all I could find on it.
I might be wrong but this might be it
1. fundamental elements
2. music notation
3. these elements
4. music scores
5. melody, harmony, and rhythm
6. melody
7. the element that holds the music together
8. into music notation altogether
9. it's harmony and rhythm that are combined into melody that create the song without lyrics.
I tried my very best to figure it out. Sorry if it is wrong.
