Review Questions

• How does the note d# function within the context of a B major scale, and what intervals does it form?
  • In the B major scale, d# serves as the third scale degree. It creates several important intervals, such as a major third with B and a minor sixth with G. These intervals are crucial for building chords and understanding their harmonic relationships within the scale.
• Discuss the significance of d# in forming dominant seventh chords and how it contributes to harmonic tension.
  • In a dominant seventh chord built on A, for instance, d# acts as the major third. This specific interval creates a strong pull toward resolving to the tonic chord. The tension created by d# is essential for establishing a sense of movement in music, leading to satisfying resolutions when returning to the tonic.
• Evaluate how misidentifying d# could impact your interpretation of a musical piece's key signature and overall harmony.
  • Misidentifying d# can lead to confusion about the key signature of a piece, potentially altering the understanding of its tonal center. For instance, mistaking d# for eb could lead to incorrect chord analysis and poor execution of harmonic transitions. This misunderstanding may affect performance, composition, or analysis by distorting the intended emotional impact of the music.
