The pianist Han-Lin Yun came up with the idea for this CD after an online lecture on "The Colours of Keys" by Professor Arnulf von Arnim, who has been an important musical mentor to her for many years.

It was and is always the keys that we as listeners pay particular attention to when examining tonal works: We follow the modulation in a composition, we compare the different works of one and the same composer, we look at when and where he uses which key (or "colour") for his work or a certain passage. Slowly and surely our senses grasp the threads that lead us to the mood of the composer. Depending on the key, we sense cheerfulness or gloom, heavenly exultation or loneliness, sadness or transfiguration and recognize that these moods call for a very specific key.

On her first solo CD, Han-Lin Yun has brought together 26 exemplary works that, in her opinion, clearly represent the mood of the respective key. She has added two of the keys that are to be considered separately as enharmonic confusions to the 24 keys: F sharp major (keys that are the same as G flat major) and D sharp minor (keys that are the same as E flat minor).

The text also contains the pianist's own, very personal interpretation, including her perception of colour and the backdrop against which this has a very special effect. The listener can, no, must decide for himself whether or where he agrees and where he wants to follow his own, different perception. Does the mood that an intermezzo, a song, a prelude, an etude puts him in correspond with the pianist's explanations? What is going on inside him? What colour, what background does he see? A truly melodious and atmospheric, perhaps even intoxicating adventure!
