• What is it? The note a seventh above the root. It's what makes a seventh chord a seventh chord.
• Why does it matter? It introduces dissonance and creates a need for resolution. Think of it as the spicy ingredient in your musical dish! 🌶️
• Tendency Tone: Especially in a V7 chord, the chordal seventh (4th scale degree) wants to resolve down to the 3rd scale degree, just like the leading tone wants to go up to the tonic.

#Why the different rules?
