This piece was originally composed for solo piano and explores the way in which our subconscious minds influence our waking lives. A persistent dream can be a positive hope but also a fear or an omen.
In many cultures across the world, birds of the corvid family such as ravens and crows have long been signifiers of loss and foreboding, and yet their symbolism is complex. As talking birds they can also represent prophecy and insight connecting the material world with that of the spirits.
So, this piece is very much like those ‘magic eye’ pictures and what you hear really depends upon how your brain is wired.
I really feel that Johanna's beautiful image perfectly captures this mythological interpretation of the music.
