ANSWER:
First geometric transformation:
Musical Note 1-2 and Musical note 8-9. It's the same note, only it has two geometric transformations.
The first is a reflection on the x-axis, this to give it the opposite direction and then a reflection on the y-axis, to obtain the position of the musical note 8-9.
We can see it below:
Second geometric transformation:
Musical note 7 is the same musical note 13, the geometric transformation that occurs is a 180° rotation clockwise, just like this:
