You know when you climb stairs in the dark and count one step too many? Your foot hangs there, waiting for a floor that never came. Tap the player below: E7 is that foot in the air.
Listen first
What you just heard
Why does it sound unfinished? Inside E7, two notes are at odds: G# and D. Play the arpeggio again, no rush and catch the second and the last note — the distance between them is the tritone, the tensest interval tonal music knows. E and B keep the house standing while those two argue inside it. And an argument, you know, demands a resolution.
Now it's your hands' turn
On the ukulele, the high reentrant G makes every shape light — and with four strings, every note is exposed. So grab the first position below — 1 open string to help you; the position marked with ⭐ is the easiest to play. Now the experiment that explains this chord better than any explanation: play E7, let it ring a moment, then play A. Felt the door close? Do it again. That relief is the reason this chord exists.

What is E7?
E7: E Major with Seventh. The notes are E, G#, B, D (fixed-do: Mi, Sol#, Si, Re) — the degrees 1–3–5–b7.
Where this chord lives
Its job is fixed: E7 is a dominant, and dominants live as VII7 in F# minor, V7 in A major. Translation: wherever it shows up, the music is about to move. A chart full of 7th chords is a song that won't sit still.

Where it tends to go
Treating E7 as the home chord (I) of its key, it usually moves toward the pre-dominant (F#m / A) or the dominant (B / D#°) — and the dominant pulls back home. Typically, not a rule.

When you want to go further
For soloing, E Mixolydian (E F# G# A B C# D · 1 2 3 4 5 6 b7: the major scale with a lowered seventh — the blues accent); E Lydian dominant (E F# G# A# B C# D · 1 2 3 #4 5 6 b7: a mixolydian with a raised fourth: the dominant in formalwear) cover the whole chord. And look at the first swap on the list below: that's the famous tritone substitution, the twin dominant living three whole steps from here, the one arrangers reach for when they want to arrive at the same place by a prettier road.
