i fixed the link jy,,,thanks for the heads up.
to answer your question about the dylan song, i've covered that song for about 20 years. traditionally, the chord progression is G / D / C / G / D / Am and repeats thru both the verse and chorus.
In the verse of my song, there is a sim. chord progression, namely G / D / Am in the verses.
In some versions of knockin on heaven's door, players will simplify the chords to G / D / Am repeating instead of alternating between the C and Am . Some grateful dead renditions and some reggae versions come to mind off the top of my head. In the key of the song, the root note is G and the II chord (Am) can be used as a substitute for the IV chord (C) and it creates a more "melencholy" feeling in the song. Something quite appropriate for Dylan's lamentations in this classic. doing the leadwork in Am blues also helps with that.
of course, the progressions in the chorus and bridges are qutie different. (C / G / Em / D / C9 / Am / C / D / G for the chorus) ( Em / D / Em / D / C9 / Am / C / D / G for the bridge) so the similarities end there.
but that was a damn astute observation there jy..color me impressed.
by the way, i threw a cover up there, one i sought permission to post (written). a song called john deere by fred eaglesmith. curious to what ya thought of that. that might be the only time in my life i got to play / record a 1940 something martin acoustic guitar. i think it sounds sweet.
curious to your impressions.
