Practice this arpeggio on guitar
- Play the D Dominant 7 Sharp 9 arpeggio from one D root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
- Play 3 (F#), b7 (C), and #9 (E#) in small groups and keep the major third and sharp ninth in separate octaves so both colors remain clear.
- Emphasize the sharp ninth over D7#9, then resolve it by semitone when the harmony changes.
