I'm trying to make sense of keys and modes, and I'm studying simple songs note by note to reach this goal. One of them is "You are the Government" from Bad Religion.
It starts with a riff that goes :
Fm A♭ B♭ D♭ E♭... followed by a verse that goes
D♭ A♭ E♭ Fm D♭ A♭ E♭ B♭.
The voice melody is made of notes that could come either from keys
D♭ because neither
G♮ is sung, though if I try to modify the melody, inserting some
G sounds better to me than inserting some
D♭ sounds to me like the home chord of the verse, does it make it a
D♭ lydian melody ? Or am I just in
Fm ? How do I know ?
To complexify things, the second syllable of "along" is a D, which is not of any of these scales. Is there a key change happening ? My understanding is that the
B♭ might imply a key change as it should be a
B♭m to respect the triads of the
Fm key. Is that the right way of thinking?
I think it's a fairly simple song, but it's enough to confuse me. Could you help me clarify it by critiquing my reasoning and telling me what keys and modes are used and whether there are key changes happening ?
C# majoris that
F#notes don't sound good if inserted in the melody line. Also I'm pretty sure the song starts on
F, I think the tab author didn't pay attention because these are power chords (I corrected some details in my question).
