Pinball Metropolis: The chiptune sound in the fun bass line is the part that sells me on the pinball theme! Compositionally, I think that you did a great job as the progression and harmony feel interesting. You have great variation in the different sections of the piece which drives it forward making this very fun to listen to. The part at the end of the loop is a fun fall down into the original key which is definitely one way to modulate! My favorite part of this track is at 2:15 with the simple percussion transition, such a fun way to break up the song!
The Arcade: This theme is a fun and bouncy and almost has a “your Pokemon is evolving!” quality to it. I think trying a 3/4 time signature is a very interesting choice, but it gives a bit of sophistication to the arcade portion of your city.
Overall I think these two tracks tell different sides to a fun and unique city. Great work and thank you for sharing!
