The sonata in D minor captures the traditional mood of this key: serious-minded and a little plaintive. The second of its four movements, a corrente-like fast movement in triple metre, reminds one of Vivaldi in its insistence on a tiny, constantly repeated musical figure. In the other movements, however, Bitti shows a more typical side of his style where the free spinning-out of melody, exquisitely shaped, dominates over strict repetition.
