This Fantasia in A is a beautiful piece of music. It is build on two chromatic motives, one ascending and one descendig. The piece start with the descending motif, First in whole and half notes in all four voices, then in quarter notes, again in all four voices. Then the descending motif is introduced, first in the tenor voice, then in the bass voice. Both motifs then alternate for the rest of the composition.
