Now, I'm gonna play for you and
explain to you the Bach
invention number one.
It's from this book here.
Two and three part inventions.
And what that means is in Bach's day,
most of the music was called part writing,
and so this one just has two parts.
There's no chords, just melodies.
So to be a piano player and
play this stuff, you have to
really split your brain in two.
The left hand is playing one melody and
sometimes accompanying the other melody.
And sometimes it has the melody, the main
part of the melody is in the left hand,
and sometimes they trade.
But you can hear chord changes.
If you really
just because the chords are not rhythm
doesn't mean that you can't hear them.
So the way this piece
works is it starts in C.
then it goes off into
a bunch of other keys.
It goes into the key of G
which is the key of the 5.
it goes through a bunch of minor keys.
which is a relative minor of the key.
It's in A minor for awhile.
And it's in the melodic minor.
And in the harmonic minor.
And then it weaves around and
goes back to C.
A lot of classical music does this.
It goes from the key of the one
to the key of the fifth,
which is called the dominant.
And then it goes into the relative
minor which in this case is A minor,
the sixth note of the scale of C.
So, I just wanna let you know that so it's
not some sort of unintelligible thing to
you, but if you listen hard you will
be able to hear the chord changes.
So what I did is I played the left
hand part on the piano and
I recorded it into the sequencer
that's built into this.
And you'll hear the four
little notes go blink,
blink, blink, blink and then I'm gonna
start playing right on the downbeat,
where the first melody part comes
in which is the right hand part.
I'm gonna play it on a C harmonica,
starting on the first hole.
It fits really beautifully on a C harp.
Although you do need a lot of bends in
the first octave to be able to play it.
So, here we go, two, three, four.
