FAQ
What do the different parts of the B 7(#5) chord name signify?
The 'B' indicates the root note of the chord. The '7' tells us it includes a minor seventh interval. The '(#5)' specifies that the fifth interval is augmented, meaning it's raised a half step from a perfect fifth. So, it's a B dominant seventh chord with an augmented fifth.
Why is the B 7(#5) chord considered an 'augmented chord' and also a 'dominant chord'?
It's an augmented chord because it contains an augmented fifth (#5) interval. It's simultaneously a dominant chord because it includes a minor seventh (b7) interval. The combination of these two characteristics gives it a unique sound and function.
What are the specific notes that make up the B 7(#5) chord, and how do they relate to its intervals?
The B 7(#5) chord is composed of the notes B, D#, F##, and A. 'B' is the root (1). 'D#' is the major third (3) above B. 'F##' is the augmented fifth (#5) above B. 'A' is the minor seventh (b7) above B.
Why is the augmented fifth in the B 7(#5) chord noted as 'F##' instead of just 'G'?
The augmented fifth is notated as 'F##' to clearly indicate that it's a modified fifth degree of the B scale, specifically an F sharp that has been raised another half step. If it were written as 'G', it would imply a sixth interval, which would change the chord's theoretical structure and function.
What is the primary musical role or function of the B 7(#5) chord on the guitar?
As a dominant chord, the B 7(#5) primarily serves to create tension. This tension naturally leads to a strong sense of resolution in musical phrases, especially within jazz and other genres where dominant chords are used to guide harmonic movement.
