00:27
I like to play jazz,
ジャズも好きだし
00:31

And this groove right here,
この最高のリズムは
01:05
comes from the Crescent City,
クレセントシティの伝統的パレード
01:13
the old second line.
セカンド・ラインから
01:16
(Cheers)
(喝采)
01:18
Now, one thing all those rhythms have in common
いろんなリズムに共通していること
01:25
is math,
それは数学
01:31
and I call it a-rhythm-etic.
「数楽リズム」と呼ぶんだ
01:32
Can you repeat after me? A-rhythm-etic.
Audience: A-rhythm-etic.
僕の後に続いて 数楽リズム

Audience: A-rhythm-etic.
数楽リズム
―数楽リズム
01:44
CC: Yeah.
いいね
01:46
Now all those styles of rhythm
こうしたリズムはすべて
01:50
are all counted in four
4拍子でありながら
01:55
and then subdivided by three.
3で割れるんだ
01:59
What?
どういうこと?
02:02
Yeah. Three is a magic number.
3は魔法の数
02:04
Three is a groovin' number.
3は いかした数で
02:08
Three is a hip-hop kind of number.
3は ヒップホップみたいなもの
02:10
But what does subdividing by three mean?
でも 3で割り切れるってどういうこと?
02:14
And counting off by four?
しかも 4拍子?
02:17
Well, look, think of it this way.
こんな風に考えてみて
02:19
A measure of music as a dollar.
音楽の単位が ドルだとする
02:21
Now a dollar has four quarters, right?
1ドルは 25セント硬貨4枚と同じだね
02:25
And so does a 4/4 measure of music.
だから 音楽は4分の4拍子で
02:31
It has four quarter notes.
4つの音からなる
02:34
Now, how do you subdivide?
これを どうやって割るのか?
02:38
Now let's envision this:
思い浮かべてほしいのは
02:40
three dollars' worth of quarters.
3ドル分の25セント硬貨
02:45
You would have three groups of four,
4拍のグループが3つできるね
02:48
and you would count it,
それを数えてみよう
02:52
a-one-two-three-four, one-two-three-four,
1、2、3、4 1、2、3、4
02:54
one-two-three-four. Together.
1、2、3、4 一緒に
02:56
All: A-one-two-three-four,
one-two-three-four, one-two-three-four.
1、2、3、4
1、2、3、4 1、2、3、4
02:58
CC: Okay, now you feel that?
どう リズムを感じたかな?
03:01
Now let's take those three groups of four
4拍のグループ 3つを入れ替えて
03:04
and make them four groups of three.
3拍のグループ 4つにしてみよう
03:09
And listen to this.
聞いてみて
03:13
A-one-two-three-four, one-two-three-four,
1、2、3、4 1、2、3、4
03:15
one-two-three-four, with me.
1、2、3、4 一緒に
03:17
One-two-three-four, one-two-three, come on, y'all!
1、2、3、4 1、2、3、4 皆で
03:19
All: One-two-three-four,
one-two-three-four, one-two-three-four, ah.
1、2、3、4 1、2、3、4 1、2、3、4
03:22
CC: There you go.
いいね
03:27
All right, second line.
ほら セカンド・ラインだろ
03:28
One-two-three-four, one-two-three.
1、2、3、4 1、2、3、4
03:34
One-two-three-four, one-two-three.
1、2、3、4 1、2、3、4
03:38
One-two-three-four, one-two-three.
1、2、3、4 1、2、3、4
03:41
One-two-three-four, one-two-three. Yeah.
1、2、3、4 1、2、3、4 よし
03:44
Now, that's what I call a-rhythm-etic.
これこそ 数楽リズムなんだ
03:48
Can you say it? A-rhythm-etic.
Audience: A-rhythm-etic.
さあ一緒に 数楽リズム
―数楽リズム
03:51
CC: A-rhythm-etic.
Audience: A-rhythm-etic.

03:53
CC: A-rhythm a-rhythm.
Audience: A-rhythm a-rhythm.
数楽、数楽
―数楽、数楽
03:55
CC: A-rhythm-etic.
Audience: A-rhythm-etic.
数楽リズム
―数楽リズム
03:57
CC: Yeah. Now pick the swing
beat, and do the same thing.
スイング・ビートに乗って もう一度
03:59
One, two, one, two, a-one-two-three-four.
1、2、1、2 1、2、3、4
04:02
Yeah. Mm.
そう いいね
04:12
One-two-three, one-two-three,
one-two-three, one-two-three. Whoo.
1、2、3 1、2、3
1、2、3 1、2、3
04:16
So I want to take the second line beat
セカンド・ラインのビートと
04:21
and the swing beat and put them together,
スイング・ビートを組み合せよう
04:25
and it sounds something like this.
すると こんな感じだね
04:27
Aha.
うん
04:43
A-rhythm-etic.
Audience: A-rhythm-etic.
数楽リズム
―数楽リズム

Audience: A-rhythm-etic.
数楽リズム
―数楽リズム
04:50
CC: Yeah. Hip-hop.
ヒップホップだ
04:52
Now it's using a faster group of three
3拍のグループを速いテンポですると
04:56
we call a triplet.
3連音符になるんだ
04:59
Triplet-triplet. Say it with me.
3連音符 一緒に
05:01
All: Triplet-triplet.
3連音符
05:03
CC: Triplet-triplet. Triplet-triplet.
3連音符、3連音符
05:06
CC: So I'll take all the rhythms
that you heard earlier,
これまで聞いたリズムをすべて
05:12
we'll put them together, and they sound like this.
まとめると こんな風になるよ
05:16
A-rhythm-etic.
数楽リズム
05:43
(Applause)
(拍手)

About the Speaker:

Clayton Cameron - Drummer
A pioneer in brush technique, drummer Clayton Cameron has toured with Sammy Davis Jr., Tony Bennett and jazz legend Kenny Burrell.

Why you should listen

Clayton Cameron holds a unique title: Brush Master. That's because this percussionist prefers brushes to sticks, and has spent his career perfecting the art of brush technique. Cameron grew up in Los Angeles and started drumming at a young age on empty oatmeal boxes. After college, he moved to Las Vegas, where he was hired as the drummer for Sammy Davis Jr.'s big band. "It would be Sammy's tap dancing night after night that would inspire my brush playing," says Cameron.

During his tenure with Sammy Davis Jr., Cameron played with Dean Martin and Frank Sinatra. And, after moving to New York, he struck up a longterm friendship with Tony Bennett, and spent 15 years touring with the master. Cameron recorded 15 albums with Bennett, including his Grammy-winning Tony Bennett Unplugged.

Cameron has also worked with jazz legend Kenny Burrell, who encouraged him to teach at UCLA's Herb Alpert School of Music. In addition, Cameron released his debut album in 2012, Here's to the Messengers: Tribute to Art Blakey, and formed his own group, Jazz eXplosion. Cameron has also released several DVDs over the years as well as a book, Brushworks
