Checkered one-piece dressback number46rank/position

Check No One Piece

The piece “Checkered Dress” is striking for its bittersweet lyrics that tighten the chest.

Because it interweaves major and minor keys, you might get the impression it’s hard to sing, but since there are no abrupt jumps in pitch, it’s actually easier to sing than it sounds.

The only tricky part is the beginning of the B section.

With the vowel on “o,” you have to drop the pitch twice; this approaches an advanced vocal technique known as a “fake” (ad-lib), so it does require getting used to.
