Freedom and restraint in recordings of Mozart

Robert Philip's 'Freedom and Restraint in Recordings of Mozart' applies a methodology that he developed in his book Early Recordings and Musical Style: Changing Tastes in Instrumental Performance, 1900-1950 (Cambridge, 1992), and reaches similar conclusions. He compares 'historic' and modern recordings of Mozart's instrumental works with respect to rubato, flexibility of tempo, vibrato, and portamento, and speculates that in these areas the earlier performers more nearly resemble eighteenth-century practice
