Clear, yes, but wrong. Not wrong to change it from the words Kavanagh wrote, not wrong to remove the reference to the four muses (though that's a shame because with a bit more thought it could probably have been kept) but wrong because by removing the 'word and tint' but leaving 'sound and stone' you've made a mockery of the second line, which now makes no sense whatsoever. Anyone singing this lyric passionately is just going to look like a great big stupid fool who's singing pure bollix to an atonished and confused audience.
