Interesting chart! Let's see what it shows and what it doesn't.
It shows a few characterstics of each mode:
- The 1st column summarizes specific intervals to each mode (ie: augmented 4th for Lydian, major 6th for Dorian).
- Each "cell" shows 2 chords/mode (generally the I and IV chord, but it varies according to the mode, showing the most identifying ones)
It doesn't show
- All the chords in a given mode (only 2 each)
- All the intervals in a given mode (only a few characteristic ones)
- Any modes with an altered fundamental (Bb, Eb, F#, etc.)
- The relative modes (ie D Dorian = C Ionian)
- The way in which some intervals are named (-7 for a minor seventh vs b6 for a minor 6th).
- Some characteristic notes are written twice (ie b5 for Locrian)
- F is written as "Fa" at least once, and G as "Sol"... looks like the Spanish notation
I don't see anything wrong with the chart (but I must admit I didn't go through each and every cell). As @piperii said in their comment, creating the chart yourself might be of more worth, as a learning exercise, than looking it up.
Aside from the misspellings of the modes (they end in “an” not “en”) the information seems pretty accurate. I don’t know your reasoning for the chords on the lower half of each box, some are the 4th, some the 5th, 6th, 2nd, what purpose do they serve? Mkorman mentioned they are characteristic of the modes, maybe that it your reason for including them.
My main problem is the usefulness of such a chart. You have the I chord of the 7 modes in only 7 of 12 keys. Are you wanting to learn diatonic modal harmony? If so I would suggest an approach like this example:
Im7 IIm7 bIIImaj7 IV7 Vm7 VIm7b5 bVIImaj7
Im7 bIIMAJ7 bIII7 IVm7 Vm7b5 bVImaj7 bVIIm7 etc.
You can but don’t need to write out all the chords for each mode in each key (it’s a lot of work), just use the interval relationships to learn how to play them on your instrument.
If you just want to learn the mode scales forget the chords and charts and learn the scales by intervals the same way, 2 examples:
DORIAN 1 2 b3 4 5 6 b7
MIXOLYDIAN 1 2 3 4 5 6 b7 etc.
I find it is much more important to learn intervallic relationships than just memorizing specific notes and chords because that way you can figure anything out in any key.
Feel free to comment with your goals and intentions.
