Click the green flag! (And the drumset or taco to join in with the beloved cowbell.)
I wanted to use the music blocks, and the most obvious way to do that for me was to have multiple sprites playing different instruments as an ensemble. So the cheese puffs are on piano and the fruit salad plays pizzicato strings. The taco plays drums, and you help out by playing cowbell. Originally, I'd wanted to allow users to choose their chord progression by abstracting out the music playing process into a queue of notes to play, with a single "play" event being called at the same time to play the entire queue at once. Unfortunately that took a while to attempt to implement and didn't actually work once complete (maybe implementing thread-like behavior could've worked? So a list item for each of a given # of event listeners to "play", and each listener uses a specific index of that list to determine what note to play?). So I settled for this admittedly simpler project, with a standard I-V-VI-IV progression and user-added cowbell percussion. Of course, "More cowbell" references the classic SNL skit (https://www.youtube.com/watch?v=cVsQLlk-T0s) so it's only fair that I credit them for the meme.
