Hey Robi!
That's amazing you're looking into the Modes. It's a concept I struggled with for a while, not because it was difficult, but because of how most people completely over complicated it when explaining it to me - I'll attempt to not be one of those people. However this may be a lengthy post!
In order for the Topic not to overwhelm you, I'd make sure you do some pre-Modes prep first:
The first piece of advice I'd give before touching the modes is to make sure you know all 7 Shapes of the Major Scale well - These are the 7 different starting points on the neck where you can play the scale, starting each time from a different note in the scale.
The second thing I'd reccomend is to Memorize the notes in all 12 Major Scales (without your Guitar) This will ensure that you know which notes are in each scale & will give you concrete knowledge on all of their relative modes.
The third thing I'd suggest is to make sure you know how a Major Key is built. This is when you build a Chord from each note in the Major scale. Say you used the G Major Scale for this: (GABCDEF#)
You would get:
1. G Major/Maj7,
2. A Minor/Min7
3. BMinor/Min7
4. C Major/Maj7
5. D Major/Dom7
6. E Minor/Min7
7. F# Diminished/Half Dim -
(these are really important!)
With that out of the way, Modes are basically what happens when you view the Major scale from a different starting point than it's first note (root note). When you shift the focus to a different note you're technically playing a different mode of the Major scale. Think of it kinda like the Major Scale is a chameleon that can turn in to 6 other scales depending on how it's used. For example, if you start the G Major scale from A it could be considered as A Dorian.
When you enter the world of Modes, the Major scale gets it's own fancy name: 'Ionian', and so does the Minor Scale: 'Aeolian' - So the Major & Minor sounds are also two modes already. Here are all the modes in order:
1. Ionian,
2. Dorian,
3. Phrygian,
4.Lydian,
5. Mixolydian,
6.Aeolian,
7 Locrian - (you'll want these memorized)
So for example: You've memorized the G major scale: G A B C D E F#
The modes of this scale would be:
G Ionian,
A Dorian,
B Phrygian,
C Lydian,
D Mixolydian,
E Aeoloan,
F# Locrian
Don't let the weird names intimidate you, they are just 1 Major scale being played from 7 different points (you know them already as the 7 positions of the Major Scale on the neck)
Notice how above they're numbered like the chords of the Major Scale? - this isn't a coincidence. For the Mode to truly sound like it's self, you want to play it over it's matching chord in the Major Key pattern, or at least have that chord be the center of its progression.
This ensures that your ear puts tonal weight on the right note of the scale. Think of the chameleon analogy from before, the chords are kinda like the surface that the chameleon (mode) would change to fit.
Example: Playing the 7th shape of the G Major scale over an F# Half diminished chord (7th chord in a Major Key) would give a Locrian sound (7th mode of the Major Scale). 7th shape, 7th chord 7th Mode etc.
I could go onto loads more theory here about which intervals matter in which modes, but I think it's important to first learn the sound of each mode.You can do this by trying your 7 Major scale shapes over backing tracks on youtube. You'll find backing tracks for every mode.
The next thing to do is listen and don't stop. You'll develop your own opinion of each modes sound and that's the most important thing you can have besides 'knowing' everything about them.
Lydian is one if my faves! Try searching ' C Lydian Backing track' and playing some shapes of the G Major scale over that.
Satu hal penting yang perlu diperhatikan adalah bahwa Anda dapat menganggap setiap bentuk skala Mayor sebagai Mode yang sesuai (Seperti bentuk 2 adalah Dorian, bentuk 3 adalah Frigia, dll.) tetapi sungguh, jika Anda memainkan backing track yang benar/ akord, setiap bentuk Skala Besar akan terdengar seperti Mode Anda.
Ini seperti jika semua 7 Shapes bisa menjadi Major (Ionian) maka mereka semua bisa menjadi Dorian, Frigia, Lydian dll. Jika itu membingungkan, jangan khawatir - itu akan masuk akal di telinga Anda ketika Anda memainkan backing track!
Mudah-mudahan ini tidak membingungkan, tetapi segala sesuatu di atas harus menjadi titik awal yang layak untuk membuat Anda 'mengalami' Mode - Saya akan merekomendasikan menonton video Rick Beatos di Mode untuk memahami semua Teori dengan baik. Pastikan Anda memiliki hal-hal pra-mode di bawah ikat pinggang Anda sebelumnya!
