Maj7 Arpeggios: The Lush Fourth Note

The short answer: add the major 7th to a major arpeggio — 1, 3, 5, 7 — and you get the Maj7 arpeggio: the dreamy, sophisticated sound behind bossa nova, neo-soul, and every jazz ballad's opening chord. Gitori's Maj7 Arpeggios course teaches five ways to play it across the neck.

What the 7 adds

The major triad (1-3-5) is stable to the point of being plain. The natural 7 sits a half step below the root — close enough to shimmer against it without demanding resolution the way a dominant ♭7 does. Melodically, that half step is gold: lines that land on the 7 over a Imaj7 chord sound instantly "jazz" in a way no pentatonic phrase can. The chord-theory side of this is covered in Seventh chords explained.

Where you'll use it

• Over maj7 chords — the I and IV of a major key when played as sevenths (diatonic 7th chords explains which chords those are).
• Soloing over major keys — the Maj7 arpeggio is a built-in "strong note" filter: all four tones are safe landing spots over the tonic.
• Sweep and legato vocabulary — four notes per octave gives smoother, more modern-sounding runs than triad sweeps.

What the course covers

Five patterns for traversing 1-3-5-7 across the neck — one-position shapes, spreads, and diagonal paths — each with a lesson and drill, then all of them mixed in the Find Arpeggios game against the clock. The fingering variety matters even more with four tones than three: each pattern puts a different chord tone under your strongest finger.

Before you start

Scale degrees are the prerequisite (the courses make them automatic), and the Major Arpeggios course is the natural predecessor — Maj7 shapes are major shapes plus one note, so learn the frame before the ornament.
