Quality improvement (QI) consists of systematic and continuous actions that lead to measurable improvement in health care services and the health status of targeted patient groups.
A musical phrase (Greek: ÏÏÎ¬ÏÎ· sentence, expression; see also strophe) is a unit of musical meter that has a complete musical sense of its own, built from figures, motifs, and cells and combining to form melodies, periods and larger sections; or the length in which a singer or instrumentalist can play in one breath.
Melody is a succession of musical pitches played or sung to a certain rhythm. A melody can also be thought of as the direction and shape of a musical line given by a pattern of pitches. Most melodies are derived from scales and melodies are considered the most expressive element in music, (rhythm the most physical).
