The Lost Mind of Dr. Brain/Music Region

The music region is a minigame about reassembling a short snipped of music.

The bars of the tune has been shuffled and it's your job to unscramble the tune.

Higher difficulties add further complications by mirroring the bars horizontally and/or vertically.

Strategy
Focus on one bar at a time. Start at the beginning and work your way from there.

Note that many melodies have continuity between bars, if there is a big jump then it's most likely wrong. Likewise, bars that are upside down tend to look different compared to bars with the other orientation.
