Whoa, Whoa....Let me try to understand this.
If I take the C Major scale......
And I want to start On E and play to E an octave higher......
What would be the proper name for starting on a different scale tone? Since you guys say dont label each "mode" or "sub scale" by the Greek name.
Even though E Phyrigian would look like the exact same pattern and sound the same.
This is still confusing me.
There's a lot of confusion around, and I think part of it is that we use "mode" at least 3 different ways.
1. Mode = scale. In this view, a mode is just a sequence of notes at specified intervals from a specified starting point. In this view, E F G A B C D E, absent all context, could be called the E phrygian mode.
2. Mode = key (modality). From this perspective, a mode isn't just a set of notes, as in #1. It's a set of notes *coupled with an established tonal center*. You need both to establish a modality or key. Just like key, the term mode in this sense is applied to the overall harmonic flavor of a piece or musical segment. IOW, it's not enough to just have E F G A B C D E, they have to be used in such a way that E is the tonal center. This is NOT the same as starting with the note E, which proves nothing in itself. It means that the center of gravity of *the piece or musical segment as whole*, not just one chord in it or one note in a melody, is clearly E.
3. Mode = a type of chord-scale. A chord-scale is basically a scale (of any type--pentatonic, major, minor, whole tone, octatonic, modal) "spun out" from the root of a given chord as if that root is temporarily considered a I/i, regardless of that chord's actual function of the chord in the musical context. Suppose you have an Fmaj7 in the key of C major. F is scale degree 4 in C. With the chord-scale approach, you take F as the I for the time being (even though it's a IV functionally) and you generate a scale *based on F*. This is the way many of you guys have been told to use modes, and it's precisely this approach that many of us are saying is basically pointless *in a diatonic context*, because it gives you nothing you didn't already have from knowing (a) the notes in the chord and (b) the key you're in at the moment. NOTE: chord-scales can be *extremely* valuable in other settings, just not so much for getting on top of fundamental functional harmony.
So you can play E F G A B C D E and call it practicing an E phrygian mode (= scale) if you want. You can also call it playing the C scale starting with the lowest available note on a 4 string bass. See Pacman's sticky scales thread for an illustration of this approach. But remember that if you're just practicing a scale in isolation, you're not doing anything with it harmonically. It has no real context. SO it doesn't necessarily mean you're playing "in" that mode.
If you're just starting a phrase with an E, that doesn't mean you're actually "in" E phrygian (in the sense of mode = key) or in E anything, for that matter. You have to look at what's happening in the music. Is E home base, or is C (or something else)? If C is, then you're not going to be playing in E phrygian in any meaningful sense. It won't sound like that, and it won't be that.
