About the B7 Chord
The B7 chord has a distinctive brightness and urgency that makes it stand out among dominant sevenths. Built from B-D#-F#-A, this chord is the dominant of E major—a key that sparkles with clarity and definition. When B7 resolves to E, the effect is crisp and decisive, like sunlight breaking through clouds.
B7 plays a crucial role in rock and pop music, often appearing as a secondary dominant that adds drama to chord progressions. In the key of A, B7 serves as V7/V, creating a mini-detour that makes the eventual arrival at E (and then A) feel more satisfying. This technique appears in countless songs.
On piano, B7 has an interesting physical layout with B and A on white keys flanking D# and F# on black keys. This alternating pattern creates a distinctive feel under the fingers. Once internalized, B7 becomes easy to locate by touch alone, making it valuable for improvisers and accompanists.
Music Theory & Usage
B7 is the V7 chord in E major, a key common in rock and pop due to its bright, clear quality. The resolution B7-E has a definitive character that works well for musical conclusions. In classical music, E major was a favored key for violin concertos, making B7 essential for that repertoire.
As a secondary dominant, B7 is incredibly useful. In G major, B7 is V7/vi, leading to Em. In A major, B7 is V7/V, creating a path to E. In D major, B7 can function as V7/ii, pointing toward Em. This versatility makes B7 appear in many different harmonic contexts.
