Analysis of Swing high and swing low

Swing high and swing low
While the breezes they blow -
It's off for a sailor thy father would go;
And it's here in the harbor, in sight of the sea,
He hath left his wee babe with my song and with me:
"Swing high and swing low
While the breezes they blow!"

Swing high and swing low
While the breezes they blow -
It's oh for the waiting as weary days go!
And it's oh for the heartache that smiteth me when
I sing my song over and over again:
"Swing high and swing low
While the breezes they blow!"

"Swing high and swing low " -
The sea singeth so,
And it waileth anon in its ebb and its flow;
And a sleeper sleeps on to that song of the sea
Nor recketh he ever of mine or of me!
"Swing high and swing low
While the breezes they blow -
'T was off for a sailor thy father would go!"
