This understanding helps musicians choose intervals that align with their desired emotional expression.
• Explain how an m3 can be identified on a piano keyboard and its significance in chord construction.
  • On a piano keyboard, an m3 can be identified by counting three half steps from the root note. For example, if you start on C, moving up three half steps leads you to E♭. This interval is significant in chord construction because it forms the basis of minor chords. In a C minor chord, C is the root, and E♭ is the m3, contributing to the overall minor sound that defines the chord's character.
