Diminshed 7th Chord = PORTAL to 8 Tonalities [MUSIC THEORY]
Tab and MP3 posted at my Patreon:https://bit.ly/2zFwzOO
Diminshed 7th chords aka Full Diminshed chords are symmetrical and any note can be considered the root note. They can resolve up a half step to a major chord or a minor chord (or down a whole step to a major or minor chord). Since there are 4 potential roots, this leaves us with 4 places we can modulate to from any given diminshed 7th chord. In this video I explain this concept, then demonstrate how I wrote a piece of music using this same principle.
I treated each new chord as a new key and played a unique scale over each chord. Over the diminished chord, I played the arpeggio or the half-whole scale on top. It turned into a rollercoaster of different tonalities, with each one crashing into the scene beligerantly to take over the spotlight.
One note on B double flat vs A :
A dim7 chord is constructed as root, b3, b5, bb7. We are supposed to respect the alphabet, and the 7th of C is B, the b7 is Bb, the bb7 is Bbb. I don’t find this to be very helpful in the context of this lesson so I ignored calling it by its proper name, likewise when I referred to the last note of Dº7 as B when it should be called Cb. It’s easier to figure out where to go next if we think of B, I do not find any atvantage to tying yourself into enharmonic knots in this secnario.
Other videos I’ve done that relate to this one:
