The painting is made by Viktoria Sikk, my mother. She is my first piano teacher and also a painter.
I think the piece is often played too fast. The tempo or character marking by Mr. Prokofiev is -andante tranquillo-. It means in Italian – calmly walking or calmly going.
And in my opinion the character markings can not be compared with metronome exactly. Often metronomes show, that if it is andante it should be this or that fast on the metronome. I think it is a strange approach.
When played in a slower tempo, the piece can have a lot of nuances and colors that could get lost otherwise when played in a faster tempo.
The piece is especially written for playing before Beethoven’s “Für Elise”. It needs similar technical skills as “Für Elise” but is an easier version.
It would not be good and respectful in my opinion to use such great music as “Für Elise” for practicing purely piano technique and using it as an exercise. So this piece gives an oppurtinity to master the technical skills and then pay more attention to music in playing “Für Elise”.
