The anthology 'Klangspuren' by Barbara Heller contains 76 works for piano which have been written for the Barbara Heller Piano Competition. Each title has its own personal message: Music can show an image or remind of something, be a short story and put one in a special mood. Arranged in a progressive order, the pieces are divided into two volumes: Vol. 1 contains easy to intermediate pieces, Vol. 2 intermediate to difficult pieces.
