In this thread I'll be posting quick tips to build your theory chops and fill the gaps with regards to chords, scales, harmony melody and all the other building blocks of music theoretical goodness.
Here's the first Theory Quick Tip
Each note in the major scale has a triad and a 4-note chord associated with it.
So, since you have 7 notes in any major scale, you have 7 triads and 7 four-note chords that fit into that scale.
The order for these chords is:
Triads - Maj-min-min-Maj-Maj-min-dim
Four-Note chords - Maj7 - m7 - m7 - Maj7 - 7 - m7 - m7b5
Knowing these triads and chords will not only give you more fuel for your next original song, but it will help you recognize groups of chords in a key when analyzing songs, especially for building soloing strategies over tough progressions.
*Assignment*
To better your ability to recognize chords in a key, write out the triads and four-note chords for each major scale, all 12 keys.
I will get you started with the key of C and you take it from here.
If you want to post your work for me to check go for it. I'll look it over and let you know if you're on the right path.
Triad in C - C Dm Em F G Am Bdim C
Four-Note Chords in C - Cmaj7 Dm7 Em7 Fmaj7 G7 Am7 Bm7b5 Cmaj7
Now your turn
