As he matured as a composer, Martucci returned to genres with much more depth, as the Nocturne in G flat major, Op. 70, No. 1 shows. This is probably the most famous of Martucci's piano pieces, not least because he later transcribed it for orchestra. Here we find the composer developing highly embellished, fast-flowing melodic lines, their strong singing quality pervaded by a melancholic tone, which are paired with a constantly syncopated accompaniment that gives the sense of endless forward movement.
