"Minute Waltz" But It's in MINOR KEY (Relative key)-Chopin

This is an arrangement of the famous Chopin "Minute Waltz" in MINOR KEY!

There are two arrangements for minor keys, "relative" and "parallel", and this sheet is the "relative" one.

The feature of "relative" is that the melody is not much different from the original, and the minor key is almost entirely based on chords.
