Right, I don't know me top from me bottom, I just play it.

The thing is, on the inner row, and the corresponding row
of buttons, it's actually near impossible to play a wrong
note, because if you do press the wrong button, you just
played a note that is in harmony with the right note, so
it just comes out a variation.

Playing the chords actually helps keep the bellows moving
in the proper direction.


here's a fingering chart for a D/G. Works just as well if you pretend it's
a D/G. G row is on the inside. See the I/V and IV chords on the
left hand? Note that the four buttons clustered at the bottom
give you OOM-pah for the G and D chords on press and draw
respectively on the outer two and the C-chord in both directions
on the inner two.

You will also observe, through the process of CNA (creative
noodling around) that in most simple tunes, you start on
the press and the two outer lower bass notes. Most of the
notes that you need on the down- or secondary beats (9 in
10 times) will fall easily to hand in the proper direction on
the right hand. Passing tones which require the bellows to go
the other way will generally NOT be either on a down- or secondary
beat. Just the way music is, most of the time.

You begin to appreciate a staccato approach to the left hand,
which also conserves air.

You'll also observe that on the part of the tune which uses the
V (D in this case) chord, nearly all of the notes on the beats
turn out to be those that are available on the draw of the bellows
(as the D chord is).

And of course, on the great ambiguous IV chord portions you've
got the C basses going in both directions, so you can grab the
notes and adjust bellows directions as you will.

As you progress, you'll find that there's more two it--- for
instance you'll observe that there really is a D chord in both
directions, but forget that for now. You'll also observe that
some notes that you might have reversed the bellows for are
available without doing so via a minor excursion to the other
treble row. Don't mess with that yet, either. Save that for
next month.
