  2. Calculate the spacing of the right cluster using the formula 4W = 4w+3b.

Experts always suggest correcting and minimizing the spacing gaps between the thinnest and broadest area of the rear and front edges. White keys possess the same width even in the front and back whereas the black keys are not placed exactly on the centre line of the keys possessing different spacing constellations.
