This is a very simple, yet creative black & white design. When I saw it for the first time, I thought what a great feeling would be the play the piano with such nail design. Unfortunately playing the piano is not my thing, unlike nail designs.
Basically for this design you will need black and white nail polish, thin brush and a teeth stick (or a suitable tool).
Paint your nails black then cover half of your nail white (please note that if your nails are longer, you might want to cover 1/3 or 2/3 with the white colour). Draw a thin horizontal black line, between the black and white colour, in order to make the edge smooth.
Then use the thin brush to draw 5 thin black lines onto the white nail polish, as shown on the picture.
The teeth stick is useful, when drawing the black keys – two the left and two the right, by leaving the central line empty.
When you are ready apply top coat and … go play the piano.
