A 7 Chord on Double Bass

Play A 7 on Double Bass: diagrams, finger positions, intervals, and every voicing up and down the neck for this instrument.

The A 7 chord is a dominant seventh — a major triad with a flat seventh that pulls strongly toward resolution. It is built from the notes A, C#, E, G. This page shows how to play A 7 on Double Bass with clear fingerboard diagrams and suggested finger positions.

The shape nearest the nut leaves the A and G strings open and takes the rest in position 2. The E string stays silent, so 3 of 4 sound. The root is the A string itself. It sounds from A1 up to G2. 3 voicings are charted, the highest starting in position 5.

Double Bass is bowed, with a bare fingerboard and no fixed stops, so this is really a double-stop study: two strings at a time speak cleanly, and the full stack is rolled rather than sounded at once.

Browse alternate voicings to find the one that sits best under your fingers, then compare it with the other chord types built on A or explore the same shape in nearby keys. The diagrams list the notes in each voicing so you can connect the shape to the theory behind it.
