I,m having some trouble figuring it out a nice way to change from B major to A minor. So far i've tried B -> E -> A -> Am, but it doesnt sound smooth, and I have no much knowledge about music theory and modulation, if you can help me I could learn from your answers. Thanks!
Edit: I forgot to add some context. Im asking for modulation because we are playing a guitar song in B major and we want to play another song without stopping playing, but to modulate, that song is in A major, then we want to go back to B major. Maybe we should transpose from B to C major, but i want to learn modulation. Also, instrument=guitar. Hope you can understand, english is not my language
