Learn to Play B Augmented
What notes are in b augmented?
The b augmented chord (Baug) is built from the notes B, D#, G — root, major 3rd, ♯5 / ♭6.
Baug
Two major thirds stacked: root, major 3rd, augmented 5th. The raised 5th splits the octave exactly in three, so the chord is perfectly symmetrical.
How does b augmented sound?
Dreamlike and unresolved in a floating way — where diminished tension pushes, augmented tension hovers. It sounds like a question mark.
Usually a passing chord: the raised 5th climbs from a plain major chord toward the 6th (C → C+ → C6 or Am). Its symmetry means every inversion is another augmented triad.
Where do you use Baug?
Use B+ as a passing chord: B → B+ → B6 keeps the bass still while the 5th climbs — a classic line from doo-wop to "Oh! Darling".
B reads as five sharps and scares people off the page — but the hand position is genuinely comfortable; Chopin liked starting students here for exactly that reason.
The Beatles ("Oh! Darling" intro), old Hollywood dream sequences, and jazz turnarounds where a V+ adds lift before resolving.
How do you finger Baug on piano?
The evenly spread shape sits comfortably under 1-3-5; because both intervals are wide, keep the wrist loose and let the hand open slightly more than for a major triad.
1 of the 3 keys here is black — play those with the longer fingers and keep the wrist level.
Tip: the common mistake
Treating the ♯5 as a wrong note and "correcting" it to the perfect 5th mid-passage. Commit to the raised note — its pull upward IS the point.
Reading about B Augmented is step one — recognizing it at speed is the game. Chord Rush drills it until your hands know it.
