TIMBRE & FORM
For clearity, I decided to show timbre and instrumentation with basic shapes.
I chose to represent percussive sound (drums) with a rectangular shape. I felt the fast and powerful attack of the drums needed a form that was strong and sturdy.
All of the instruments are visually presented individually and together make up the song as a whole. The drums are also made of multiple instruments the main center piece is representing the bass drum, inside the bass drum, moving up & down is the snare drum (which is equally as loud, i.e. the size), and the smaller, outside rectangles are the hi-hat noise.
Since the drums hold the song together musically, they also do so visually by being the center of the whole music form.
The keys (piano & harp) are diamon shape, at basic structure. The harp (I say harp because that was the setting I used when playing the instrument) shape is suported with two small similar diamons. The reason for the additional diamons is because of the complexity of the multiple sounds that is coming from that one instrument. The piano shape is altered a little, too. You can see there is a rectangular shape involved in the formthe reason for this is because the piano is a percussive instrument and has a stronger attack, similar to the drums, so there is a drum shape (rectangle) incorporated into the piano. Also, at points in the song, you can see there are two piano shapes working together this is two notes harmonizing with each other.
Not only is timbre being represented within the form and structure of each instrument, but timbre is being shown with how the shape of the instruments are manipulated over time.
