Here is the list of what you should be working through in the book:
Pg 15: #50, 51, 52, 53
Pg 16: #57, 58, 59
Pg 17: ALL- listen to the recording and play along when able! Use your CD that came with your book.
Pg 18: #61, 62 (listen to the full piece- so pretty! https://www.youtube.com/watch?v=POW-u-RGspY The theme you learned starts at 31:32)
#63 (remember this song in Lilo and Stitch? https://safeYouTube.net/w/ooz3)
Pg 19 #67, 68 (learn both lines A and B. Try making a recording of yourself playing one line and then play the other line to make a duet!), #68
Pg 20 #71 (eight notes with an eight rest right after sound just like staccato quarter notes. Short and separated!)
#72 https://safeYouTube.net/w/Iqz3 The theme you learned starts at :51!
Pg 21: #77 Play this one slowly, playing attention to the new notes, slurs and dynamics. This is a recording of the song- but don't worry about trying to play it that fast! https://safeYouTube.net/w/yrz3
#78, #79 (another one to try recording yourself playing one line and then play with it to make a duet!)
Pg 22: #83 (make a recording once you've learned this and try playing a round with it!)
#84 (tough but fun! "Can, can you do the Can-Can? Can you do the Can-Can...")
Pg 23 ALL (use your CD to hear this one and play along!)
