a decreasing pitch means that the wavelength
... (distance between peaks) is increasing with each peak
... the increasing distance means that the peaks reach the observer
... less frequently ... a lower pitch
this is caused by the source moving away from the observer
the opposite is true for a source moving toward the observer
