A little polka from Kabalevsky's "24 Pieces for Children", Op. 39. I've seen this book recommended everywhere and I finally decided to get a copy of it. Even though most pieces are beyond my reach at the moment (I'm prep level and the pieces range from prep to grade 3), after listening to the entire album, I can say I am in love! 😍 Some of the more advanced pieces are so good!
While we wait for me to get there, here's my humble contribution as an adult beginner:
Dmitry Kabalevsky (1904 — 1987) was a Russian/Soviet pianist and one of the most prolific composers of his time. Wikipedia has an extensive biography: https://en.wikipedia.org/wiki/Dmitry_Kabalevsky
In terms of sheet music, there are quite a few editions of Opus 39 in Amazon to choose from.
