Review Questions

• How does the C Major scale's structure influence the formation of triads within this key?
  • The structure of the C Major scale directly influences the formation of triads because each note can serve as a root for a triad. For instance, using the first note C as a root leads to the C major triad (C-E-G), while using D gives us the D minor triad (D-F-A). The whole and half-step pattern of the scale allows for specific qualities of triads, such as major and minor chords, to be derived naturally from its notes.
• What are some methods for identifying chord qualities in C Major and how do they contribute to understanding harmony?
  • Identifying chord qualities in C Major involves examining the intervals formed between the notes within each triad. For example, a major triad like C major consists of a major third (C to E) and a minor third (E to G). By learning these interval patterns within C Major—major, minor, diminished—you can categorize all diatonic chords. This knowledge helps musicians understand how different chords function together harmonically in compositions.
• Evaluate how common chord progressions in C Major can affect musical expression and composition.
  • Common chord progressions in C Major can significantly shape musical expression by creating emotional contexts. For example, the I-IV-V-I progression establishes a sense of resolution and completeness often used in folk music. By evaluating these progressions' emotional impacts—such as tension from V leading back to I or movement from ii to V—composers can craft music that resonates with listeners on an emotional level. Mastering these progressions enables musicians to convey various moods and themes throughout their pieces.
