I sat down to write a bass line to a simple garage punk ditty my guitar player wrote, thinking with four chords and eight bars it ought to be easy to come up with a good "Attractions" type bass line. Emaj /Amaj /Bmaj /Amaj /Emaj /Amaj /Dmaj /Bmaj The line came pretty easily, so I decided to work with it a little more and try to write it out in standard notation. I assumed it should be written in Emaj, at first, but where does that D major chord come from? It sounds right. Why won't it write right?
