[OC] Children Pieces (2017-18) - Full Set

'Children Pieces' is a set of 16 piano pieces for children I composed around 2017 to 2018. It is easy before the following pieces gradually increase in technique and difficulty. And the difficulty curve also applies to the structure of each piece, getting more complicated as it goes.
The first piece of the set shows 2 main themes in their purest form. The first one, the primary theme, is transformed and used in every following piece to create the cyclic form throughout the set. The second one is also developed but found only in some pieces as the secondary theme.
Thank you so much. And I hope you enjoy my music.
