FAQ
What notes make up the A 7(#5) chord?
The A 7(#5) chord is composed of four specific notes: A, C#, E#, and G. These notes represent the root, major third, augmented fifth, and minor seventh intervals, respectively.
What do the 1, 3, #5, and b7 intervals mean in the A 7(#5) chord?
These numbers represent the musical intervals relative to the root note 'A'. The '1' is the root (A), '3' is the Major Third (C#), '#5' is the Augmented Fifth (E#), and 'b7' is the Minor Seventh (G).
Why is the E# note used in the A 7(#5) chord instead of F?
The note is spelled E# to maintain the correct intervallic structure derived from the root A. E# functions as the Augmented Fifth relative to A, whereas F would be a different interval (a minor sixth) and would not align with the chord's theoretical construction as an augmented seventh.
How is the A 7(#5) chord related to the family of Augmented Chords?
