So true. I-IV-V is pretty standard, I could honestly name a bunch of songs off the top of my head that follow it, several of my own included. Any specific variations/deviations you could give me on that?
Yes and no. I don't have time to explain it all, not that I even know enough to do so compared to some of the folks here who have forgotten more music theory than I will ever know......
Basic rules I apply when searching for chords to use outside of the normal 1,4,5.
Learn the harmonic minors: In the key of C for example, Am (Bapu's favorite chord BTW) is the harmonic minor to C. You can easily throw in the Am chord where you play the C maj chord. Not always but in many cases.
With all major and minor chord voices, you should learn and use the 2nd, 4th, 5th, 6th, and 7th variations of the root chord and also the 9th 11th and 13th. Each one of those variations has a different color and sound to them. Some stand alone, and some of them scream to be resolved. Resolving a chord simply means it doesn't sound complete or finished and wants to go somewhere else to be "home". Usually to the root chord of the key.
I use 6ths and 7ths in Maj & minor all the time. They are essential.
Happy accidents.... every now and then, as I'm playing, and not really thinking...kind of in a Zen moment..... I will grab the "wrong chord" and it just works.
The more theory you learn the more naturally it will come to coming up with colorful inversions and chords.
Look on Youtube.... for jazz musicians who are playing the instrument you have as your strongest instrument currently.....the jazz players, probably more than anyone else use all of the colorful chord variations and inversions and you can learn much from them.
If guitar is your instrument, buy one of those chord books..... the ones that say "The Only Chord Book You Will Ever Need" or "7500 Essential Chords for Guitar" and work on some of the "other chords" in various keys... stuff like: G7sus4, G7b5, G+, Gdim, G13b5b9, etc... the book I have has approximately 75 different chord variations per basic root chord.
Learning just a small handful of those chords will expand the possibilities for you when you write.
Best wishes.....have fun.
