Quotations
Clementi, in his "Introduction to the art of playing the piano-forte" (1801) still had to advise pianists that : "the best general rule is to keep the keys of the instrument suppressed during the whole length of the note" (p.8) and "whenver the composer leaves the legato or staccato to the taste of the performer, the best rule is to use the legato in most cases and to reserve the staccato in order to give particular passages more spirit and to enhance the higher beauties of the legato."
