Arpeggios Used
An arpeggio is simply the notes of a chord played one at a time rather than all together. Two arpeggios are used in this line.
✔️ Amin7 Arpeggio
The chord Amin7 (Am7) contains:
A (root)
C (minor 3rd)
E (5th)
G (minor 7th)
Am7 arpeggio: A – C – E – G
✔️ Fmaj7 Arpeggio
The chord Fmaj7 contains:
F (root)
A (major 3rd)
C (5th)
E (major 7th)
Fmaj7 arpeggio: F – A – C – E
Relationship Between Them
Notice that the Am7 arpeggio (A–C–E–G) contains three notes from Fmaj7:
Playing Am7 over Fmaj7 emphasize :
A (3rd)
C (5th)
E (7th)
G (9th, extension)
This is why jazz players often use an Am7 arpeggio over Fmaj7. It emphasizes the upper structure of the chord and naturally adds the colorful 9th (G), producing a richer, more modern major-7 sound.
Over an Fmaj7 chord:
Fmaj7 arpeggio = outlines the chord directly.
Am7 arpeggio = outlines the 3rd, 5th, 7th, and 9th of Fmaj7, creating a more melodic and less root-focused sound.
For example:
Fmaj7 arpeggio: F – A – C – E
Am7 arpeggio over Fmaj7: A – C – E – G
Both sound consonant over Fmaj7, but the Am7 arpeggio often sounds more "inside jazz" because it highlights the upper chord tones and extension.
