Chemistry March

So I made this song for a Chemistry Final, and it was supposed to be an art piece that represents 3 things we have learned. Here are the three things:
The phrases in the song are 8 measures, showing that atoms want 8 valence electrons to be balanced.
The notes in the main theme are color coded. The higher notes represent the higher energy, and are more purple. The lower notes represent lower energy, and are more red. Red is the lowest energy, while purple has the highest energy. Yellow and green are in the middle.
The parts with faster notes and lighter articulations are louder, going above the rest of the instruments and being louder, showing that they are lower density, and therefore are above the rest of the song. The parts with lower, fuller, and heavier notes represent higher density, and go below the rest of the instruments, and are quieter.
Hope you enjoy!
