What does the "#11" in A# 7(#11) signify?
The "#11" indicates an Augmented Fourth interval, which is an extension added to a standard dominant seventh chord. This specific interval creates a unique harmonic color, often associated with a jazz sound, and is built upon the basic root, major third, perfect fifth, and minor seventh.
Why does the A# 7(#11) chord use notes with double sharps like C## and D##?
The use of double sharps in the chord's note list (A#, C##, E#, G#, D##) ensures that the theoretical spelling of its intervals from the root (A#) is maintained accurately. For example, C## is the Major Third above A#, preserving the correct interval quality, even if it has an enharmonic equivalent like D natural.
What is the key difference between an A# 7(#11) chord and a regular A#7 chord?
The primary difference is the addition of the #11 (Augmented Fourth) interval. A standard A#7 chord consists of the Root, Major Third, Perfect Fifth, and Minor Seventh. The A# 7(#11) adds that specific Augmented Fourth, resulting in a more complex and harmonically rich sound compared to the basic dominant seventh.
How is the A# 7(#11) classified as a "Dominant Chord"?
The A# 7(#11) belongs to the Dominant Chord family because it contains a Minor Seventh (b7) interval from the root (G# in this case). This characteristic Minor Seventh creates a harmonic tension and a strong pull towards a tonic chord, defining its dominant function in music.
