One geometric transformation seen on the sheet music image is rotation. Notes 7 and 13 are both circles with stems pointing in different directions than the other notes. Note 7 has a stem pointing down on the left side of the circle, while note 13 has a stem pointing up on the right side of the circle. These rotations create a different orientation for these two notes compared to the other notes on the staff.
Another geometric transformation seen on the sheet music image is reflection. Notes 8 and 9 have stems on the left side of their circles, pointing down, connected by a horizontal line. This creates a reflection of the stem and horizontal line compared to notes 1 and 2, which have stems on the right side of their circles, pointing up, and also have a horizontal connecting line. This reflection creates a symmetrical appearance between these two sets of notes.
