Why G7 sounds this way
Why does it sound unfinished? Inside G7, two notes are arguing: B and F. Go back to the audio and catch the arpeggio note by note and catch the second and the last note — the distance between them is the tritone, one of the tensest intervals in tonal music. G and D keep the house standing while those two argue inside it. And an argument, you know, demands a resolution.
