The minor seventh flatted fifth
"Unfortunately, I got to Bm7-5 …and my jaw dropped. How do you pronounce it?? How do you play it??"
Here's my attempt to respond based on my limited understanding of music theory:
First some basic chord symbols:
# Represents a sharp or one half step up
b Represents a flat or one half step down
+ Means an augmented note (sharp) and if by itself often means +5.
- Means a dimished note (flat)
5 Refers to a chord with just the root and the fifth (C5 is C and G)
So to pick apart the Bm7-5 you would start with the chord:
B minor chord (Bm): B - D - F#
Then add the "dominant 7th" which is the flatted seventh:
B minor seventh chord (Bm7): B - D - F# - A
Then replace the fifth (F#) with the "flatted fifth" (F):
B minor seventh flatted fifth chord (Bm7-5): B - D - F - A
The chord has a very dissonant sound. Check out Thelonious Monk's "Round Midnight". I believe it's built with "m7-5" chords
