Notes in First riff = E, F#, G, A, A#
Notes in Fourth riff = E, F, G, G#
With the diminished scale in mind, is it okay for a song to begin with E dim and end up in B dim?...Should the song stay in the same key signature?...Do the notes within a certain scale determine the key of an enitre song???
AND/OR--If these progressions/notes were played slowly...say, the first note was held for four beats--could you do something like a bass fill in E minor during the duration of that one particular note????
Please help. I'm very confused......
