Memorizing - finding patterns in Czerny 18

Yuliya talked me through patterns in #18 and played it with the score, then played it "cold" (book shut) with only 1 mistake.

Left hand:

MM 1 - 4 descent: Left hand is diatonic G, with 1/2 step grupetto embellishments. Yuliya plays it all 2-1-2-3-1-2-3-1 (even the f#)-2-3.

MM 5 & 6: ascent is mix of diatonic G and a chromatic addition every third, with same embellishments: steps are 1e-2f#-3g-3,1/2g#-4a (note unlike diatonic scale, this has two 1/2 steps in a row)-5b-6c-6,1/2c#-7d (ibid). Note it starts on E, which is relative minor of G, and sticks in the G# and C# to the G scale.

M 7: 2 major 3rds except stick in the earlier F#-G 1/2 step, with same 1/2 step embellishments, then minor 3rd: 1 d- 3f# - 3,1/2g - 6 (3d fm G)b - 1 (minor 3d fm B)d.

MM8: diatonic G w/ no grupettos.

MM9: descent: LH descends by whole steps with variation of thirds. mm 9 - 12 have same base notes as do mm1 - 4; the difference is that mm 1 - 4 use 2nds for the grupetto embellishment while mm 9 - 12 use thirds. Last note in bass of mm4 is f natural but is f# in mm 12. The trebles of these two sections have the same note as upper note in mm 1 - 4 and lower treble note in mm 9. The treble notes in 1 - 4 are supported by their 6ths, while the treble notes in 9 - 12 are supported by their 3rds, so they are the same notes, different placement.
