Hey Friend,
B minor was the root chord for the last key we studied (B minor, in case you were distracted two weeks ago). In the key of F# minor, B minor is the IVm chord in the harmonic progression.
I II° III IVm Vm VI VII
F#m G#° A Bm C#m D E
The B minor scale provides us with the notes we need to form the chord. Use the 1 3 5 notes (B, D and F#):
1 2 3 4 5 6 7 (8)
B C# D E F# G A (B)
Like the other six chords that make up the F# minor harmonic scale, the F# minor scale has the ingredients baked in to make the B minor chord:
1 2 3 4 5 6 7 (8)
F# G# A B C# D E (F#)
As I’ve said before, knowing this stuff isn’t necessary to be a guitar player. Think of this information as the ingredients that make up the chords. If you’re anything like me, when someone puts a piece of delicious cake down in front of you, you don’t usually stop to ask what the ingredients are. You just grab a fork and dig in.
When it comes down to it, it’s not the knowledge of the individual notes that gets the chord played, it’s the shape your fingers form. Every chord has a shape, applied by following a pattern.
Learn the shape and you learn not only the chord of the moment, but every chord that utilizes that shape. You just have to know where to put your hand.
So put that to use with the exercises. Learn the shapes, and remember where they go on the neck.
Gotta roll… mandatory "fun day” at work. Ha! Oh, happy Friday!
Peace~
