Begin by playing the B Major scale ascending and descending at 80 BPM using a metronome, one note per beat. Once comfortable, practice in thirds (B-D#, C#-E) to build intervallic familiarity. Spend 5 minutes daily on this pattern before increasing tempo by 10 BPM.
Try these progressions with the B Major scale: Bmaj7 - Emaj7 - F#7 - Bmaj7 (I-IV-V-I) or Bmaj7 - C#m7 - Emaj7 - F#7 for a more stepwise movement.
