When two half steps are added together, they equal a whole step, represented on the
piano by two keys separated by an intervening key. Whole steps occur between two
white keys, two black keys, and in some cases, a black key and a white key. Half steps
and whole steps are examples of what are called
intervals – specifiable distances
between two pitches. To refer to a pitch one half step higher than a particular pitch, we
use the designation sharp. Thus, the black key to the right of C is C sharp. To refer to a
pitch a half step lower, we use the designation flat. Thus, the black key to the left of D
is D flat.
