The Modal Approach by Tom Colohue
Part Three: The Tonal CentreEstablishing A Tonal Centre This is obviously paramount to all modal and tonal play, because a tonal centre can also be a root note. Allow me to explain. A tonal centre is a singular note, around which intervals are structured, that the intervals cause the piece to resolve to. It's the resolution that's most important here. You need to ask yourself: where does this piece of music want to go?' In key-based, or tonal, music, the root note quite clearly acts as your tonal centre. For example, the major scale will always want to resolve to its root note. The minor scale is a good way to look at the differences here. If you play the minor scale, but do not focus on notes such as the third, sixth and seventh, it won't have the minor sound. This is actually an example of suggestive play, but we'll get to that in a bit. Spending time in any particular key means that the tonal centre will be established, because the notes themselves will cause the piece to resolve in a particular way. If you're in E major, and you play a few chords/notes before returning to E, your tonal centre is safely established as E. If you then make a move towards A major, through your choice of chords for example, the tonal centre will change, but there will also be a few moments when the tonal centre is neither E nor A, but in flux and undefined. As musicians, we typically strive to avoid this, but accidentals are named so because they are out of key. If you're using suggestive play, or in fact going modal, you need to be able to use notes from outside of the major scale, while still resolving to one particular tonal centre. This means that, once you're tonal centre is established, the safest way is to commit to it. After that, it's all about making your move, then returning to safety as quickly as possible by moving smoothly back into the established tonal centre. Note Stability The notes that you choose to use are entirely up to you, but some cause much greater dissonance than others, much like some actors being fun to work with and some being outright bitchy. Let's have a quick look at the basic stabilities for the twelve notes of modern western music. The root is, quite clearly, the strongest and most stable note that there is, since all music is built around it. The two strongest notes after that are the fourth and the fifth. This is why I - IV - V progressions are so very popular. The fourth and fifth are perfect intervals, being neither major nor minor. They are the least affected notes in modal formulae, and are almost always safe landing spots in solos that cause no dissonance and add no particular sound or style to the piece. After that it gets a little more complex. Being that the major scale is the basis of all music, major notes are inherently stronger than minor ones. The leading tone, or major seventh, pulls towards the root incredibly strongly, making it one of the stronger notes itself, but it does somewhat shoot itself in the foot because it does not hold stability in itself all that well due to that pull. The minor second does not succeed from the other side. It is on the opposite end of the spectrum entirely. I see a chart coming.
This is your basic chart of note stability, based on the strength of notes to the root, and also how often different notes are used in certain intervals. For example, utilising a minor third instead of a major third is common in many respects because, though it is unstable, it's not so unstable as to potential break the tonal centre. The minor scale might be starting to make sense to people now. Why does it sound minor? Suggestive play. You're using accidentals to bring in the sound of Aeolian, but you're also coming back to more stable notes such as the root, perfect fourth and perfect fifth. Suggestive Play As an example, let's use A major again.
R |- completely stable b2 |- very unstable 2 |- stable b3 |- unstable 3 |- stable p4 |- extremely stable b5 |- extremely unstable p5 |- extremely stable b6 |- unstable 6 |- stable b7 |- unstable 7 |- very stable R |- completely stable
Starting from the root, we're going to look at a simple lead line, utilising an accidental to do suggestive play to achieve a Mixolydian overtone.
A, B, C#, D, E, F#, G#, A
It's a simple line, but it contains a minor seventh, which is the Mixolydian modal note. In order to maintain the tonal centre, I've used two of the most stable notes available. The leading tone, or major seventh, and the root itself. This means that, despite the out of key note, the moment of flux is intensely short, but the choice of note does show a small Mixolydian influence. Now, in no means is this strong because, put simply, it isn't modal and is only suggestive. You're suggesting Mixolydian rather than actually playing in it, but that's what we're talking about here. Another option is the drone, or holding tone. This is a continually repeated note, to maintain the tonal centre while you work towards something else. Let's use Phrygian as the example here, since it gives more options to derive.
e|-----------------| B|-----------------| G|-----------0-1-2-| D|-----2-0-2-------| A|-0-4-----------0-| E|-----------------|
Again, relatively simple, but there's one rather large difference here beyond your choice of modes. The minor second is much less stable a note than the minor seventh, and the drone makes it's connection to the tonal centre all the more obvious. The dissonance is quite clear. This is basically all that suggestive play is, but you become bolder and more inventive as time goes on, especially with your choice of notes and modes. The b5, for example, is present in the solo to Stairway To Heaven. As we know, the b5 is suggestive of Locrian, while also being the least stable note to land on. Teasing A Resolution In order to get the most out of your suggestive play, you have to push the boundaries a little, especially that moment of flux. This means that, if you want to strengthen the differences that particular modal notes can give you, you need to have a little fight with that tonal centre to make it stay put regardless of what you do. However, you can't just wander completely off track into a modal formula, because you're not playing modally. You have to hold that tonal centre, or you'll slide straight back into the major scale or, worse, slide through a haze of dissonance into a different key altogether. Now that you know your stabilities, you can play the field and experiment. Maybe alternate accidentals, or throw a few together before you return to safety? Maybe push a little harder and go for a flat second or diminished fifth. Personally, I quite enjoy using a whammy bar with a diminished fifth, since you can bend the note either up to a perfectly stable fifth, or down to a perfectly stable fourth. One way suggests Locrian, while the other way suggests Lydian. This is extremely dissonant, but that doesn't mean I dislike doing it. Use your suggestive play to pull away from the tonal centre ever so slightly. Then, when you come back to it, it will be all the stronger. Playing in the boundaries of the major scale is a perfectly good way to be a musician, but if you're after learning about modes, you're looking for something different. Suggestive play teaches the theory behind accidentals, using modal notes for tonal methods for a small hint at the real sound of modes. Play with the unexpected options available to you. When To Let It Go Sadly, there are many reasons that you should return to the safety of the established tonal centre. You could have strung too many accidentals together. The volatile lack of stability could have gone off on you. You could just want the piece to sound simple again. It's easy to go too far out of the major scale comfort zone. It's important that, during your experiments with suggestive play, you intentionally go too far. You want to learn where your own line is, and what would make you cross it. Most importantly though, people listening to you have their own line, and it might not be the same as yours. Dissonance sounds good to some and bad to others. Ultimately, how you use your instrument and stray from the safety of everyday music defines you as a musician, but Muse are still more popular than Symphony X. So play suggestively. See what sounds you can get out of that tiny modal flavour. A single note of difference separates the style and feel or the natural minor from the style and feel of the harmonic minor after all. The smallest change often makes the biggest difference. Everything in these columns is useless if you don't experiment on your own and know when to stop experimenting. That's it for this week. I know it's been mostly tonal applications, which aren't really modes, but the modes themselves can come through in many ways, and they're a valuable theoretical tool even outside of themselves. Next week it will be modal progressions, which is the meat of the matter. True modal playing comes from modal play, and modal progressions are a huge part of that. Over a modal progression, the tonal centre is not as much of a concern, and this makes a suggestive lead line much stronger. You'll be playing within the realms of modes in no time.
