Cold-hearted

"The songs were sung by every one who possessed so much as an echo of a voice: they were quoted—copied—got by heart—in fact, we cannot imagine how the world of singers went on in the days when ‘Tara’s Hall,’ and ‘The young May Moon,’ and ‘The Meeting of the Waters,’ were strains unborn. And now, after so many changes and casualties have passed over it, when the work is at last brought to a conclusion, when the last tones of the harp have died away, those must be colder-hearted than ourselves who can avoid remembering how many who welcomed the first with eager gladness, are now deaf to the sweet cunning of music for ever!"
