'White Keys - Black Keys' was written by Barbara Heller in December 2003 for a pianist who likes to improvise and loves a certain freedom in a work. Although an order of the parts is pre-determined in her composition, all sections may well be combined in a different order. The short chorale can be followed by a free improvisation which also makes use - ad libitum - of the playing in the strings.

• Lyrical, soft, poco rubato
• Softly flowing, like water
• Radiant
• Strong tone color, reaching upwards
• Storming upwards, loud
• Chorale, play very calmly
• Rubato, as new life
• Epilogue
