The Snow Goose part 1

‘Rhayader' is the introduction of the main character in the story of the Snow Goose. His introduction is rather sensitive with the sound of a flute, but soon gets a firm grounding with the drums and keyboard, while the tambourine gives it a light and dancing touch. And it ends again with the sensitive flute in a repeating rhythm.

...his heart was filled with pity and understanding. He mastered his handicap, but he could not master the rebuffs he suffered, due to his appearance. The thing that drove him into seclusion was his failure to find anywhere a return of the warmth that flowed from him...

But then, with the start of ‘Rhayader goes to town', there is a remarkable change. The drums make a determined statement and the guitar comes in very strong. 

...he was twenty-seven when he came to the Great Marsh. He had travelled much and fought valiantly before he made the decision to withdraw from a world in which he could not take part as other men. For all the artist's sensitivity and woman's tenderness locked in his barrel breast, he was very much a man...

This is made very clear by the drums, keyboard and guitars, while they express the powerful spirit of Rhayader. Then the music changes again and while still holding this power, it starts to move. It sounds like a strong and determined walk as he goes to town. But in that movement he looses his power bit by bit, and takes him out of his centre.
And so he returns to his sanctuary, which he build for the birds but which he needs himself just as much. The story describes that he has a safe place for all hunted creatures.

... this made Rhayader happy, because he knew that implanted somewhere in their beings was the germ knowledge, of his existence and his safe haven, that this knowledge had become a part of them and, with the coming of the grey skies and the winds from the north, would send them unerringly back to him...

‘Sanctuary' is a very balanced guitar piece, the plucking of the strings that give a basic ground and the space to express the guitar.
So in this self created sanctuary, where he can embody his spirit by developing his skills of painting and managing his boat, he, one day gets a visitor, and ‘Fritha' enters.

... desperately frightened of the ugly man she had come to see, for legend had already begun to gather about Rhayader, and the native wild-fowlers hated him for interfering with their sport. But greater than her fear was the need of that which she bore. For locked in her child's heart was the knowledge, picked up somewhere in the swamp-land, that this ogre who lived in the lighthouse had magic that could heal injured things. She had never seen Rhayader before and was close to fleeing in panic at the dark apparation that appeared at the studio door...

This is expressed by the music which gives the feeling of something that will disappear with the slightest movement. 
And then there is another change as ‘The Snow Goose' starts and the guitar is showing it's most amazing moves.

...he told here the most wonderful story. The bird was a young one, no more than a year old. She was born in a northern land far, far across the seas, a land belonging to England. Flying to the south to escape the snow and ice and bitter cold, a great storm had seized her and whirled and buffeted her about. It was a truly terrible storm, stronger than her great wings, stronger than anything. For days and nights it held her in its grip and there was nothing she could do but fly before it. When finally it had blown itself out and her sure instincts took her south again, she was over a different land and surrounded by strange birds that she had never seen before. At last, exhausted by her ordeal, she had sunk to rest in a friendly green marsh, only to be met by the blast from the hunter's gun. A bitter reception for a visiting princess, concluded Rhayader. We will call her La Princesse Perdue, the lost princess...
