"Upon a careful analysis of this term phrasing as it is understood and used by scholarly musicians, what exactly do we find its meaning to be? We find it used in three senses : first, as referring to a clear perception of the formal division of music into well-defined sentences and their parts; secondly, as referring to the right method of marking those divisions so that in the rendering of the music they may be evident to the hearer; and, thirdly, as referring to the correct and expressive rendering of each division."
