Why are linking verbs or helping verbs sometimes omitted? Is it for a rhyme/rhythm in the sentence? Below is the lyrics of the song "Valhalla calling me". Why did the writer omit "is" in "Valhalla calling me"?
The 2nd line has no verb in it. How is that possible? What does this type of sentence structure usually mean? (I have found a similar sentence structure, where there is no finite verb, in many songs)
Lyrics:
Ships on vigor of the waves are skimming
Barren summits to the verdant plains
Each horizon is a new beginning
Rise and reign
Far from the fjords and the ice cold currents
Ravens soar over new frontiers
Songs and sagas of a fate determined
Shields and spears
Vows of favour or the thrill of plunder
Pull together for the clan and kin
Clank of hammers and the crash of thunder
Pound within
Oh-ho-oh
The echoes of eternity
Oh-ho-oh
Valhalla calling me
Oh-ho-oh
To pluck the strings of destiny
Oh-ho-oh
Valhalla calling me
Valhalla calling me
