The C11 chord (also known as C dominant 11), is a dominant chord. It has a major triad with a minor 7th, major 9th and 11th (compound perfect 4th).

The notes in C11 are:



The harmony is ultimately determined by the chord’s root. But many arpeggios feature other chords that you can use or play over the main chord.

From the root: C11
From the 3rd: E-7b5(b9)
From the 5th: G-7
From the 7th: Bb△




An arpeggio is a collection of distinct notes that together make up a chord. Each note that makes up a chord is referred to as a chord tone.
