How to get the Improvisations Achievement for Genesis Noir

How to get the Improvisations Achievement

To get the secret Improvisations achievement you need to do the following. At the start of the chapter head right and complete the simple wave puzzles. Continue going right and ride a train which you need to drag towards it's destination. You will then encounter a bass player, repeatedly press on him using the A button of your controller, so he gets angry and a battle starts. The sequence from left to right is:

3, 1

3, 1, 2, 4

3, 1, 2, 4, 2, 3

You can play any notes you want and the bass player will play them back to you. There will now be a sequence where you need to turn the keyboard black by dragging holding the A button on your controller and dragging across it. When the keyboard is completely black click on one of the audience members to begin a sequence where you need to build a city with your note. Once a train appears drag it off the screen to finish the level and unlock the achievement.
