Two Sketches of Melody Interactives

In my first idea, I drew some little people riding bikes on stages. Those stages are dicided by pitches a user play by keyboard. Clicking on the people could change their colors which stands for different timbres. Pressing relevent keys can build stages of different lengths and heights.

For my second idea, I want to make a monster singing out loud. This idea comes from a project called Blob Opera. In my idea, using mouse to drag the moster would change the pitch of sound and pressing keys may change the timbre and make it stop or start singing.
