His best song in the book is imo the Song of the Sea
To the Sea! To the Sea!The white gulls are crying,
The wind is blowing, and the white foam is flying.
West, west away, the round sun is falling.
Gery ship, grey ship, do you hear them calling,
The voices of my people that have gone before me?
I will leave, I will leave the woods that bore me;
For our days are ending and our years failing.
I will pass the wide waters lonely sailing.
Long are the waves on the Last Shore falling,
Sweet are the voices in the Last Isle calling,
In Eressea, in Elvenhome that no man can discover,
Where the leaves fall not; land of my people for ever!
Other stuff he sings:
From the mouths of the Sea the South Wind flies, from the sandhills and the stones;
The wailing of the gulls it bears, and at the gate it moans.
What new from the South, O sighing wind, do you bring to me at eve?
Where now is Boromir the Fair? He tarries and I grieve.
Ask not of me where he doth dwell- so many bones there lie.
On the white shores and the dark shores under the stormy sky;
So many have passed down Anduin to find the flowing Sea.
Ask of the North Wind news of them the North Wind sends to me!
O Boromir! Beyond the gate the seaward road runs south,
But you came not with the wailing gulls from the grey sea's mouth.
Galadriel about Legolas:
Legolas Greenleaf long under tree
In joy thou hast lived. Beware of the Sea!
If thou hearest the cry of the gull on the shore,
Thy heart shall then rest in the forest no more.
Finally the song of Nimrodel:
An Elven-maid there was of old,
A shining star by day:
Her mantle white was hemmed with gold,
Her shoes of silver-grey.
A star was bound upon her brows,
A light was on her hair
As sun upon the golden boughs
In Lórien the fair.
Her hair was long, her limbs were white,
And fair she was and free;
And in the wind she went as light
As leaf of linden-tree.
Beside the falls of Nimrodel,
By water clear and cool,
Her voice as falling silver fell
Into the shining pool.
Where now she wanders none can tell,
In sunlight or in shade;
For lost of yore was Nimrodel
And in the mountains strayed.
The elven-ship in haven grey
Beneath the mountain-lee
Awaited her for many a day
Beside the roaring sea.
A wind by night in Northern lands
Arose, and loud it cried,
And drove the ship from elven-strands
Across the streaming tide.
When dawn came dim the land was lost,
The mountains sinking grey
Beyond the heaving waves that tossed
Their plumes of blinding spray.
Amroth beheld the fading shore
Now low beyond the swell,
And cursed the faithless ship that bore
Him far from Nimrodel.
Of old he was an Elven-king,
A lord of tree and glen,
When golden were the boughs in spring
In fair Lothlórien.
From helm to sea they saw him leap,
As arrow from the string,
And dive into the water deep,
As mew upon the wing.
The wind was in his flowing hair,
The foam about him shone;
Afar they saw him strong and fair
Go riding like a swan.
But from the West has come no word,
And on the Hither Shore
No tidings form Elven-folk have heard
Of Amroth evermore.
