(19) "First real attachments - Ode to the Love". Seeing that the transition from childhood to adolescence is gradual, the first part takes again the A major tonality of the end of the children's part. A long theme (81 notes!), in range of adolescent-voice (C key), very melodious, evokes a "song of love". Entirely played with the left hand, its comes again with counterpoint on right hand, by Quint and later Oboe, and interludes of openly romantic nature; later, the theme is splitted in chromatic quavers (eighth notes), with counterpoint by Cromhorn (2 voices); the part ends with the 'triumphant love", with theme on the pedal-reeds, in ff.
(20) "Nostalgia for Childhood". This part begins with a rather melancholy choral (5-6 voices) in A minor and C major, introducing the theme self, evoking the nostalgia for childhood that the adolescent suddenly realizes it is over and will never come back. The theme, in C major, and its fellow in A minor, alternate: in range of adolescent-voice, and an octave higher in range of child-voice, as a last attempt to cling to that bygone period.
After that, we attend an increasing revolt against the passage of the time, reaching its paroxysm in tortured chords, with all the rage of GO and Pedal (reeds 32'); but that revolt is unavailing, and we come again in C major, despite the still present anger; this passage ends with an isolated held note, at the extreme bass tone of pedal, in fff, evoking the future state of the adult: childhood (high notes) has gone, and adolescence (middle notes) will not last. The head theme comes back, to express resignation, in "Unda Maris" and then in "Voix Céleste"; the end chord (pp) is in range of child-voice (keyboard) and adult-voice (contrebasse 32' of pedal), and the adolescent will have to choose between both...
(21) "In best form". A first theme, fast and lively, is played by Tierce, Quint and Cornet, on 3 keyboards. An other theme follows, reminiscent of children's songs, to describe the mischievousness inherited from childhood; this theme is played by Oboe, Cromhorn and Trumpet, on 3 keyboards.Then the first theme comes again briefly, to bring the conclusion that happens on an humoristic note (isolated note on trumpet 16' alone).
(22) "Starting in active life". This part, fluctuating between A minor and E major, expresses the high spirits and the enthusiasm with wich a young person launch out into active life; his new and even not-conventional ideas can be successes: "theme" of beginning, where hands and feet seem to do anywhat, but the global effect is good; the mixing Mixtures of Choir and isolatd notes of Bombarde of pedal has also a good effect although strange.
(23) "Towards a new life". The preceding part links with this one by an isolated note of pedal in fff; here are evoked the prospects of an adult's life, with all its promises, its richnesses, the possibility of dooing "great things". It's the corresponding to the end of the part "Children", in more lucid and resolute. From that a Maestoso movement, with complex chords, to keep both melodious and imposing aspect. The organ, in all its strength and majesty, is in perfect accordance with the young person, conscious of his overwhelming possibilities.
The part "Adolescents", begun in A major, has ended in C# major, showing so the split of joining an adult's world, entirely different.
