Thirds

Post by sam54 »

The concept I am struggling with consists of major keys that are a minor third apart. e.g. the key of E major and G major where we can move between either keys and borrow chords or a single chord. For example- if I were playing in the key of E and the chord progression was: E - F#m - G#m - A etc. I could play E - F#m - (G) - G#m - (Am) the chord in brackets are borrowed chords from the key of G. Which chord and how many chords you borrow will depend on the song and the musical effect you want to achieve. Further examples of parallel major keys are - Original key C - parallel key Eb Original key A - parallel key C Original key D - parallel key F Whew!

Borrowing chords is a fantastic way to add depth! Just be careful not to lose the emotional core of your progression. The G chord can add a nice tension, but make sure it feels right in the overall vibe of your song. It's all about the feel, mate.

You're on the right track! Just remember that when borrowing chords, the voicings matter. For E major, try using a G major shape for that borrowed G chord to maintain consistency in tone. Also, consider how your gear responds to these changes; certain pedals can accentuate borrowed chords beautifully.

Honestly, this sounds overly complicated. Why not just write a good progression without all the borrowing? Sometimes less is more. Keep it straightforward and save the theory for later.

Blimey, this is a bit heady, innit? Borrowing chords can be clever, but don't overthink it. Just play around and see what sounds good, mate. Music’s supposed to be fun, not a math class!
