I have written an instrumental for guitar(12 str) for a 500 year old song. Sort of medieval and very simple. I discovered the song itself is sung in Em, Am, G and D. The instrumental is in Am only, with various string choices and open notes. It starts and ends in Am, but I would like to use it and have it flow naturally into the introduction of the song(Em first chord). I don't mind if it's a string walk up and not the whole chord strummed.
The way it sounds now is not too objectionable, but as it is now I need to dead stop the Am chord, and "curtain raise" Em to the song in a one beat strum. The laps here is a bit awkward and it sounds too much like an intro.
I have heard some songs that do this and they still sound pretty good. I may just leave it the way it is. Perhaps, Em and Am are natural harmonics in the music world. But I find they are slightly off for a walk up.
Any tips would be appreciated. Thanks
