Great fun learning

This is great for generating some useful melody, but may need more instructions to fully realize the potential. Which page's which note is the actual C?
And please could you make left side dot selection to have more touch area, because when I am using iPhone se2020, it is very hard for me to switch between pages it often hit musical notes. Thank you.
