You my soul, you my heart, You my bliss, O you my pain. These words from Widmung (Dedication), a song by Robert Schumann transcribed by his wife Clara, sum up their symbiotic relationship. Marriage bonds aside, they were to apply equally to Clara and Johannes Brahms. Whether in letters or in notes, this 'trio' communed in the ideal and inexpressible realms of art. On Lettres Intimes, Bulgarian pianist Plamena Mangova presents a recital of works by all three composers.
