Impromptu

Gorgeous grew the common walls about me.
Floor and ceiling very Heaven became,
Music all within me and about me,
Brain on fire and heart aflame;
Yet I could not speak for shame,
And I stammered when I tried to speak the name.

Gone the light and vanished all the glory,
Clasping, grasping Fancy strives in vain;
None can sing the song or tell the story,
Walls are only walls again,
Now the stammering tongue speaks plain.
O, the ache of dreary dullness worse than pain.
