key

This is the sound of my keys being put down on my wooden desk. This is one of my favorite sounds because it reminds me of coming home after a long day and emptying out my pockets before bed. My keys consisted of four metal keys and one plastic car key fob.

Modulation is when the music changes from one key to another. For this example, the main attraction is the string section (Violin, Viola, Cello and Bass). This segment of the movement starts in D major and moves to D minor, with a slight movement into F Major. The key modulation can sometimes happen with changes in tempo, dynamics, melodic shapes, rhythm structure, etc. For this excerpt, the rhythm is very busy within the mid voices of the strings and some accent variatons on the high voices. Because it is the finale, it's common to end the piece strong with a statement and in this case, it also involves a subtle variation to create tension and release with the key modulation. With that in mind, the dynamic ceiling changes as well. When it's in the major key, the sound's very powerful and moving, while the minor key presentes a more subtle and quiet, yet moving section of the piece.
