Alongside each pictoral image of Darwin is a process for the development of the musical structures. This one-movement piece, to some extent in a style contemporary to the time, sets up and establishes the motifs which form the basis of the whole work. Thus, the introductory section to this work for violin and piano also serves as the musical foundation of all four stages of Age of Wonders - in one sense the introduction is a life in its simplest, amoebic form. It begins with the purest of beginnings, middle C, and the interval of an octave (the first within the harmonic series). The closing two notes of the first phrase, and the first of the second, form the next most simple of structures, a three-note scale figure (which has proved to form the fundamental component of the whole work). The remaining feature of this introduction is the second interval in the harmonic series, the 5th. But musically, there is a sense of space, anticipation, and if such simplistic structures allow, 'Wonder'.

The piece breaks in to the image of a child, energetic, scatty, uneven in attention (and phrase length). The addition of the next interval of the harmonic series and a quotation from one of a remarkable series of works written in the year of Darwin's birth, Beethoven's Piano Sonata No. 24, are points within this section, which follows the most simple of sonata forms with essentially one subject only.

These musical elements provide the essence of the whole work, the intervals continue to be introduced and the three-note scale figure reworked. The sections that follow acknowledge the death of his mother when he was eight years old, his studies at school and as a medical student (including his distaste for autopsy). Darwin himself went on to study (and enjoy life) in Cambridge, and one of his friends' favourite pastimes was to confuse and test Darwin's recognition of well-known melodies played in a different way - naturally I have put one in this section.

One of the major influences in Darwin's life at this point was Professor Henslow, and they could often be seen walking and discussing Darwin's increasing interest in science. I have referred to an incident which disturbed them both, the near lynching of two prisoners by a mob (by now Darwin is a young man with a social conscience, conventional but beginning to think beyond established boundaries). The circumstances which surround Darwin's acceptance by Fitzroy as ship's scientist on the Beagle are well-documented, and after reference to this the piece closes with a revision of the introductory material.
