Pitch is represented as height (y-axis) in the Melody Window.

While absolute pitches are not represented, the horizontal line through the middle of the window is in fact "Middle C". Pitch positions relative to this may be calculated by the number of half steps up or down. Notes will automatically snap to half-step positions and there are a series of faint horizontal lines in the window background to indicate the half step intervals. The highest note is an octave above Middle C and the lowest note is an octave below Middle C.
