Komponen Chord
maj7
Major 7 (1–3–5–7). Karakternya halus, elegan, dan stabil, lazim dipakai sebagai warna tonik modern pada jazz, city pop, neo-soul, dan ballad. Dibanding triad mayor, kesannya lebih sophisticated.
b5
Alterasi ♭5 (diminished fifth/tritone dari root). Menambah disonansi kuat dan dorongan resolusi. Sangat umum pada diminished, half-diminished, dan varian dominant altered.
Fungsi Harmonik
- Dominant function: cenderung resolusi kuat ke chord target (tonik/tujuan cadence).
- Cocok untuk secondary dominant, turnaround, dan tension-release movement.
Roman Numeral Analysis
- V7alt (fungsi dominan kuat menuju i/I)
- V/V7alt (secondary dominant altered)
