 it is possible that many phrases could be the same 

 song exactly, repeated at intervals, or the song might 

 be varied, but it would be a separate phrase at each

A " strain," on the other hand, means a succession 

 of sounds uttered in a definite order, and which may 

 be repeated, perhaps several times, in one phrase, as 

 commonly occurs in the very long phrases of the 

 skylark.
