What the A11 chord sounds like

An eleventh chord has six notes in theory. In practice the third is left out (it clashes with the eleventh), so it sounds like a 9sus4 – a modern, open dominant.

How do I read the chord diagram?

Strings run from the lowest (left) to the highest (right) – tick “Left-handed” to mirror it. Rows are frets; a number at the side shows the starting fret. Dots are fingers (1 index, 2 middle, 3 ring, 4 little), a long bar is a barre, × means don't play that string and ○ means play it open.

Why is a note missing from some A11 shapes?

On a fretted instrument you can't always play every note of a 6-note chord. In an eleventh chord the third (C♯) is normally left out because it clashes with the eleventh. The fifth (E) and ninth (B) may be dropped – the chord keeps its character without them.

How is the A11 chord written?

The chord symbol is A11, and its full name is A eleventh.
