Concerning the Spiritual in Art, 1910
Part II: About painting
The man that hath no music in himself,
Or is not moved with concord of sweet sounds,
Is fit for treasons, stratagems, and spoils;
The motions of his spirit are dull as night;
And his affections dark as Erebus;
Let no such man be trusted. Mark the music.
(The Merchant of Venice, Act v, Scene I.)
"Musical sound acts directly on the soul and finds an echo there because, though to varying extents, music is innate in man".
"Everyone knows that yellow, orange, and red suggest ideas of joy and plenty" (Delacroix).
