LeFevre composed 12 sonatas for the clarinet. All were published in his method which dates from 1802. LeFevre composed various works whose main purpose was educational but nonetheless excellent concert pieces all too often overlooked today. Harp & Co's choice in this recording was intended to give each of them a particular atmosphere emphasizing their melodic virtuosity and rhythmic energy. In doing this we followed the precepts of LeFevre who recommended to his interpreters to vary their playing in order to avoid boring the listener by repetitive style. The sonatas were written in the form of duets for clarinet and an accompanying instrument cello. An improvisation for the harp is a welcomed addition in order to enrich the harmony of the bass part.
