This study works on pimi arpeggios. The sequence is similar to the arpeggios the students learn in earlier pieces, with a few small differences.

The main principle is “extension timing”, or the sequential method by which we extend fingers back to the strings while others flex.  

One helpful way to think about arpeggio extension timing is as though the thumb and fingers are on two teams.  As one team plays, the other one gets ready, and vice versa.
Read these arpeggio sequences slowly.

Step 1: Fix pim on three strings (3, 2, 1 for example).
Step 2: Play p.
Step 3: While leaving p “in the air” (resting against the i tip joint), play i.
Step 4: With both p and i “in the air” play m but at the same time return i to string 2!
Step 5: Play i, at this point p returns to its string i and m are both inside the hand.
Step 6: Play p and return both i and m to the strings.
Step 7: Go to step 3 and repeat.
