How to read this arpeggio
The chord tones are shown as pitch classes first. In the fretboard tool, square markers represent C# root notes, while circular markers represent the remaining tones in the arpeggio.
Use the interactive fretboard to locate the C# root notes and connect the remaining major 7 chord tones across standard tuning.
This same arpeggio shape is also commonly called C# Major Seventh or C#Maj7.
Chord construction and defining tones
C# major 7 is defined most clearly by 3 (E#) and 7 (B#). The major third sets the chord quality, while the major seventh adds its close, unresolved pull toward the root.
Harmonic use
Use this arpeggio over C#maj7 and major-key tonic or major-seventh chords where the natural seventh is present.
Practice this arpeggio on guitar
- Play the C# Major 7 arpeggio from one C# root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
- Connect 3 (E#) and 7 (B#) through multiple positions, resolving the major seventh upward to the nearest root.
- Improvise over C#maj7 and place the major seventh on a weak beat before resolving it to the root.
