Theory:

Where the voice of the wind calls our wandering feet,
Through echoing forest and echoing street,
With lutes in our hands ever-singing we roam,
All men are our kindred, the world is our home.
Explanation:
  
This poem is about wandering singers. They are a band of musicians who wander from place to place singing songs that carry a message; they do not have a home or any fixed place of stay.
 
The singers feel that the sound of the wind invites them to forests and streets. That is their call to start their musical journey. They hear the sounds repetitively as it keeps ringing in their ears.

The wandering singers carry many instruments in their hands, one of which is the lute. A lute is similar to a mandolin. They roam around singing songs with their lutes. They treat everybody they meet as their own family or relations, as they do not have a particular family or home. The whole wide world is their home.
