Jean-Noël Hamal's musical language is a perfect reflection of this transitional period in which the Baroque galant style merges into the classical style. One senses in Hamal's music a communicative vitality, a charmingly poetic note, a keen sense of elegant melody and a theatricality in dynamic contrasts which in some ways evokes the Mannheim school. As soon as he was able, he exploited the ample space available by writing works for two choirs and two orchestras. He seems also to have had a very pronounced preference for major tonalities (he even went so far as to write an astonishingly cheerful Dies irae in C major) and for very readable harmonies, although these sometimes risk being too predictable or conventional. But he was also capable of being a visionary: by their tripartite structure and the autonomous form his symphonies make him a precursor of the classical symphony. He is equally capable of entirely unexpected surprises and attractive details, as is apparent in his motets delivered respecting the practices then in force in Liège by Nicolas Achten and Scherzi Musicali ensemble, mixing subtlety and theatricality.
