Phrase Rhythm and phrase structure

Phrase Rhythm and phrase structure


Part I - Phrase Separation and Connection
 an aspect of the continuity of phrases is how and when phrases are separated or connected.  In some cases phrases are rhythmically separated , in others, a separation is implied.  New phrases may also begin when the previous one ends.  at the point of cadential arrival, with an upbeat or anacrusis. 

Note:
Anacrusis- One or more unstressed notes before the first bar line of a piece or passage.

Frequently, phrases are connected together to give a stronger sense of continuity.  The reason and affect of such choices vary according to the style of the music and the context of the phrases.  Phrases are usually connected in one of four basic ways.

1. Elision - The omission of a sound or syllable 
2. Melodic or bass line links
3. continuation of accompaniment
4. overlapping of lines

 An important point to consider is weather the phrase link is heard as a part of the preceding phrase or as an upbeat and a lead-in to the next phrase. 
Phrase overlaps are less frequent than elisions and phrase links, and occur most often in contrapuntal textures.

Part II - Phrase Expansions
 The idea that phrases can be expanded is based on that some parts of the phrase are additions to more basic essential elements. 
Phrase introductions occur in three common forms:

  1. Accompaniment figures that initiate a phrase into the entrance of  the phrase melody
  2. Motivic anticipations
  3. Elongated upbeats
