Learning music is a process that should follow a sequence based on level of importance. A performance suffers If essential parts of the whole aren’t represented.
Example: a musician can play the pitches to a part because it is a familiar melody or because they have heard other members of their section play it, but they guess on the rhythm during practice and performance. No matter how much attention that musician puts on expression, style, articulation, and tone; their performance will always have a fundamental flaw that will have negative effects on the rest of the ensemble. These steps are a suggested sequence for practicing music. With enough experience, some steps will be able to be done during sight reading while others will still require active attention.
