"Where words fail, music speaks."
— Hans Christian Andersen
Where Words Fail Music Speaks
Where words fail, music speaks.
About this quote
This line is widely attributed to Andersen and cited to What the Moon Saw and Other Tales, but no verified passage containing the exact phrase has been located in the original text by researchers. The work itself — a series of poetic sketches narrated by the Moon — does describe musicians and musical imagery, but the specific wording "where words fail, music speaks" does not appear to be traceable to Andersen's original Danish manuscripts.
