Among the youngsters, the Frenchman F-B. Mâche, with his Duo for violin and piano - despite studying Greek archaeology - was still the most in tune with the music. In any case, Mâche understands his métier, knows how to think logically and produces a civilised sound which, even if it needs levelling, is worth hearing.

The most gifted piece is by the Frenchman F-B. Mâche, a duet for violin and piano dating from 1956. In this piece, something 'happens', important musical messages are launched. However, Mâche should ensure greater horizontal coherence (melodic lines) and verticale (consonance), by working together on the meaning of the two instruments.
