This song has what I call “Pop Rhythms” starting at measure 10 in the right hand. These rhythms look really complex and they can be difficult to count. However, you can learn them much faster if you just listen and imitate. Sometimes it’s easier to just hear how it sounds and then try to play it, instead of trying to count the beats.
To make this song harder: The left hand is pretty plain. See if you can make something up based on what I gave you. Also, you can play the right hand in octaves at measure 33 and play loud instead of soft there.
To make this song easier: When the left hand has two notes play together, just play the bottom note. Also, you don’t have to take both hands up at measure 34. You can play that part just like at measure 18.
