It might not say "ethereal music", but I can't ignore the feeling from the rest of the text that the ethereal-ness of the elves would also be in their music.

Gildor:

‘Listen! They are coming this way,’ said Frodo. ‘We have only to wait.’ The singing drew nearer. One clear voice rose now above the others. It was singing in the fair elven-tongue, of which Frodo knew only a little, and the others knew nothing. Yet the sound blending with the melody seemed to shape itself in their thought into words which they only partly understood.

Before long the Elves came down the lane towards the valley. They passed slowly, and the hobbits could see the starlight glimmering on their hair and in their eyes. They bore no lights, yet as they walked a shimmer, like the light of the moon above the rim of the hills before it rises, seemed to fall about their feet. They were now silent, and as the last Elf passed he turned and looked towards the hobbits and laughed.

Hall of Fire, Rivendell:

Frodo began to listen.

At first the beauty of the melodies and of the interwoven words in elven-tongues, even though he understood them little‘ held him in a spell, as soon as he began to attend to them. Almost it seemed that the words took shape, and visions of far lands and bright things that he had never yet imagined opened out before him; and the firelit hall became like a golden mist above seas of foam that sighed upon the margins of the world. Then the enchantment became more and more dreamlike, until he felt that an endless river of swelling gold and silver was flowing over him, too multitudinous for its pattern to be comprehended; it became part of the throbbing air about him, and it drenched and drowned him. Swiftly he sank under its shining weight into a deep realm of sleep.

There he wandered long in a dream of music that turned into running water, and then suddenly into a voice.

Lothlorien, Caras Galathon:

Haldir knocked and spoke, and the gates opened soundlessly; but of guards Frodo could see no sign. The travellers passed within, and the gates shut behind them. They were in a deep lane between the ends of the wall, and passing quickly through it they entered the City of the Trees. No folk could they see, nor hear any feet upon the paths; but there were many voices, about them, and in the air above. Far away up on the hill they could hear the sound of singing falling from on high like soft rain upon leaves.

EDIT: Huh, I already had posted one of these quotes above.

Well, at least I'm consistent...
