question about E minor scale

Hello
Hope that you can me with this question

I was playing today in Minor scale. I started in B then went to A, G, F# and finally to the back to E. Why did the B fit in so well with this scale as I have always started on a root note of the scale.

many thanks

In any scale you play, there is a note in the scale called the dominant, and in the case of the diatonic scales (i.e. the major and minor scales) the dominant is the fifth note of the scale. The dominant note is the note whose own scale has the most in common with the scale you are already playing. That make sense? Probably not. Better explanation:

Notes in the E minor scale: E F# G A B C D
Notes in the B minor scale: B C# D E F# G A

Notice how there is only one note different? B minor has a C# instead of a C, otherwise it has identical notes to E minor. This is why B minor is a good scale to play after having played E minor. If you want to sound really clever about it, if you were to start off playing the E minor scale and then changed to B minor you have 'modulated to the dominant.' Hope this helps!
