Hello
This in regards to the course Blues Style Level 1[br]The Notorious Key Of E[br]Can some one explane an open B7 chord.[br]My understanding is a B should contain [br]B, A and F notes. In a previous course[br]it was said to make a 7th you add the 7th note[br]and flatten it (1/2 step back).[br]B7 contains B, D#, A, B, and F#.[br]If A is the 7th note why is it not flattened.
Thanks
Ken
The key of B major is
B, C#, D#, E, F#, G#, A#, (B)
For B major triad chord we take root, the third and the fifth.
B - D# - F#
To make it (dominant) 7th chord we add flat seventh to the triad.
Seventh is A#, so flat seventh is A.
B7 = B - D# - F# - A
Order of the notes doesn't matter, as long it contains those notes it is B7.
Open B7
e| --- 2 ---
B| --- 0 ---
G| --- 2 ---
D| --- 1 ---
A| --- 2 ---
E| --- X ---
Same using note names
e| --- F# ---
B| --- B ---
G| --- A ---
D| --- D# ---
A| --- B ---
E| --- X ---
Thanks for the help.
I forgot about breaking down the B to its component notes.
Your answer was very helpful. I'm new to figuring out what notes are in a scale.
and now I can see where I went wrong.
Thanks again.

Thanks Christopher. [br]I still have big holes on my music theory knowledge. But the one thing I know is scales and chords relationship. And I'm glad to pass the knowledge forward. I feel that explaining things to others is a great way to improve my own knowledge.
