Comment on Music Theory for the 21st-Century Classroomparent

Comments

I'm starting to read the course at the beginning, and a depressing aversion to explaining why and not only what seems apparent, probably motivated by a desire for brevity and informality that also causes serious defects. For example:

- 1.3 grand staff: "Note that middle C is always clearly notated in either the upper or lower staff and never floats between the two staves." It doesn't tell that the choice of which staff the notes belong to indicates which hand should play them.

- 1.4 accidentals "... are characters that can be placed before notes to raise or lower them." Not to reuse staff locations to distinguish the notes one needs to use.

- 1.5 Enharmonic notes: "When two notes sound the same but are written as two different notes on the staff, the written notes are said to be enharmonic." This is totally wrong, not merely maddening, but before discussing scales any decent explanation is impossible.

- 3.3 Scale Degree Names: in the middle of chapter 3 (minor scales) because there's no f** definition of what a scale is.

- 6.1 Introduction to Triads: "A triad consists of three notes stacked in consecutive thirds. A triad is also called a chord as well as a harmony. (Harmony also refers to chord progressions.)"

It's sad because many other places benefit from the concise and elegant treatment, for example:

- 5.5 Augmented and Diminished Intervals: "Augmented intervals are one half step larger than perfect or major intervals and diminished intervals are one half step smaller than perfect or minor intervals."
