Welcome to Music Theory Third Floor Page Two of this site!
If you’ve reached this page by accident and you are new to music theory then you may want to back track a bit through this site. Have a look at the scheme of work video and some earlier pages on Music/Guitar Theory.
If you are here to get some clarification, understanding and practical working knowledge about what are often referred to as the
"qualities" of musical intervals then carry on here.
The major scale is the centre of the universe.
(…spoken with a loud echoing voice coming from someone who sounds like they have a robe and big white beard!)
That’s where we start.
You have to be pretty familiar with the major scale for what is coming to make sense. Being familiar in terms of theory as well as aural perception would be best. If you are not sure if your ear has caught up to your head go to the major scale interval trainer now. (make a cuppa first though)
> =is Greater than (by 1/2 step) < =is Lesser than (by 1/2 step)
A = augmented M = major m = minor
d = diminished P = perfect
Before you need to go lie down in a darkened room hear me out!
We now need to forget about the numbers. In other words it doesn't matter if we are talking about for example, a major second or a major third or even major sixth or seventh. What matters is that we are talking about an interval with the quality of being major. That's it.
Furthermore if you look at my little music theory rules formula you will see that any major interval is less than augmented and greater than minor.
This means that any major interval raised by half step becomes augmented. Likewise any augmented interval lowered from a raised major returns to major. It also means that any major interval lowered by half step becomes minor. Reciprocally any minor interval raised by half step becomes major. You see where I'm going here? The qualities of music theory in a nutshell!
Pick a quality.... any quality ..."but don't show me it"... sorry just kidding...
Lets say minor. What happens to minor when you lower it by a 1/2 step?
Is your answer that it becomes diminished? Great you win a prize! (erhm..you feel happier right)
What does a perfect interval become when you raise it by 1/2 step?
Did you say augmented ?? Awesome!!
What happens to a perfect interval lowered by 1/2 step?
Yes, it becomes diminished.
What about any minor interval raised by 1/2 step?
Please tell me you said it becomes major... yes ? Great!!!
You just follow the flow of the chart!
Now go to a shop and get a little note book or pad and a pencil with a rubber on it.
Walk around for a couple of days scribbling your new found secret music theory code into your book analysing it to death as you go. While the eggs are cooking or the cereal is getting to the right sogginess or the kettle is heating up, at the bus stop, traffic jam, before the micro wave pings.... you get it?
If you don't quite get it yet ...don't worry you can always use the "contact me directly" box below to ask me questions. I will happily answer them no strings (or sales pitches) attached.
