Hey everyone, it's Colleen here for part 2 of Your Tetrachord Magic.
OK, so Last week we made a tetrachord with the WHOLE WHOLE HALF pattern and your instructions
were to find that on your instrument starting with every possible note that you can make,
so I hope that you are very sick of that tetrachord. Now, I'm going to ask you to duplicate that
WHOLE WHOLE HALF one that you made; Make another one.
AND Make THIS one, which is…..
WHOLE HALF WHOLE. OK.
And it sounds like THIS. So, you play the note, SKIP one, you DON'T
skip one now, and then, you DO SKIP one. So, those are all whites, but of course you
can start with any. See what are we going to do? oh right A flat OK… SKIP ONE, now
you DON'T skip one, and then you skip that one and go to the next one. Let's do ONE
MORE of those. We're starting on a E flat here….OK.
So you play the first one, skip that one, now DON'T skip, and now DO SKIP.
That's That. Now I'd like you to color this new pattern,
duplicate it twice, and laminate it if you want to like we did
last week. You now have four cards; they look like this,
and now it's time to NAME them. The W W H we're going to call "I" for
Ionian; The W H W we're going to call "D" for
Dorian. Look what happens when you put two I's together:
So, here we go, Whole, Whole, Half, with a WHOLE BETWEEN them, there's the second one,
and poof you've got yourself the IONIAN scale made of two I tetrachords.
Here's another one: there's the whole, there's the whole BETWEEN them, OK? and
there's the half at the end to finish it off.
Now we're going to do two D's. What happens when you put two D's with a whole between
them? There's one WHOLE, there's the Half in
the middle, the WHOLE, now the WHOLE BETWEEN them, another WHOLE, HALF, and the WHOLE to
finish it off. Now things get interesting: Here's an I
and a D. So here's the first note, a WHOLE, another
WHOLE, now our HALF, the WHOLE BETWEEN them, another WHOLE, now the HALF in the middle
of the D, and a WHOLE to finish it off. How about that? Different scale altogether
huh. Let's do another one. OK. The WHOLE, the WHOLE, and the half, that's the first
"I", now we're on the D, there's the half in the middle of it, and finish that
off. Well, we can go the other way: a D and an
I. Starting on this note, there's the first
note, the WHOLE, the half in the middle, the WHOLE, the WHOLE between them, the WHOLE,
the WHOLE, and the HALF to finish it off. and ONE MORE: Here's our Dorian, (our D),
There's the HALF in the middle, the WHOLE, there's the WHOLE BETWEEN them, and this
is an I so it's TWO WHOLES and a HALF. Well, I hope your mind is starting to be blown.
BECAUSE….. from two tetrachords, we've made FOUR SCALES,
and in all twelve keys that amounts to forty eight scales that you can form EASILY. And
these are (uh) four of the more important scales that are used in all classical and
jazz music. So it now behooves YOU to practice those scales. And come back next week and
we'll do more with them. Thank you for watching! Bye!
