Listen first

What you just heard

Here's the curious part: G#, the new note, lives a half step from A — that close, it should grind. And it does. But C# and E hold the room, so the grind turns into shimmer instead of a fight. Play the arpeggio again, no rush all the way to the last note and wait: you'll feel the spark without the fire. It's tension, domesticated — which is why it sounds expensive.

Now it's your hands' turn

On the electric guitar a chord needs only a few clear notes — the amp sustains them and fills the space, so you mute the strings you are not playing and let the tone carry the rest. So go with the first position below — 2 open strings as a bonus; the position marked with ⭐ is the easiest to play. Then do the before-and-after: A, then Amaj7. The second is the first one after sunset. Run it a few times: this chord tends to feel odd on the first pass and addictive by the third.

What is Amaj7?

Amaj7: A Major with Major Seventh. The notes are A, C#, E, G# (fixed-do: La, Do#, Mi, Sol#) — the degrees 1–3–5–7.

Where this chord lives

Across keys, Amaj7 works as VImaj7 in C# minor, IVmaj7 in E major, IIImaj7 in F# minor — almost always the deluxe I or the elegant IV. It was bossa nova's signature and became the world's: today it shows up from jazz to indie without asking permission.

Where it tends to go

Treating Amaj7 as the home chord (I) of its key, it tends to go toward the pre-dominant (Bm / D) or the dominant (E / G#°) — and the dominant pulls back home. It's a tendency, not a law.

When you want to go further

For improvising, A Ionian (A B C# D E F# G# · 1 2 3 4 5 6 7: the plain major scale, where everything starts); A Lydian (A B C# D# E F# G# · 1 2 3 #4 5 6 7: the major scale with a raised fourth — one extra step of daydream); A Lydian ♯2 (A B# C# D# E F# G# · 1 #2 3 #4 5 6 7: a lydian with a raised second, harmonic-major color) wrap the whole chord. And the jazz shapes at the end are the same four notes spread across the neck, for the day you want to sound like an arranger.

Improvising in context

To improvise over Amaj7 as home, the A Ionian scale fits entirely — it contains every note of the chord. And when the dominant (E) pulls back, the leading tone Ab is the note that wants to resolve home.
