My daughter's piano teacher asked me if I had a copy of the Minuet in Anna Magdalena's Notebook. I did try to ask "which minuet" but she just said the one everyone starts with. So could someone enlighten me as to which one you get your pupils to play first.

I have some anthologies with different Minuets in but none of them seem to me particularly easy for my daughter and her teacher's idea was to give her an "easy" piece to work on so that she can improve legato phrases in one hand without getting distracted by what is going on in the other hand.

I am guessing that she would mean the one that goes : D GABC / D G G etc. Not that easy, in fact - and the LH has quite a lot to do, especially in the 2nd half. Probably on the high side of Grade 1( or nearer Grade 2) .

I would imagine it's that one - I did it for my Grade 1 in 1978

In the left hand is there a minim chord GBD in the first bar?

In which case I do have a copy but had decided that this was not easy. For a start she can't play a legato octave from G to G in the right hand or any of the left hand octave stretches or even the quavers from D to C in the left hand as she can only stretch a sixth.

The piece my daughter was playing in her lesson was the first "Little Sonata" in the Classics to Modern book (which is in one five finger position throughout). Her teacher said that over the summer she had got into the habit of accentuating the right-hand note every time the left hand plays something. Personally I think my daughter has always done this (and given that we were away for eight weeks over the summer without a piano I don't think it is a habit she could have acquired by poor summer practising).

In the left hand is there a minim chord GBD in the first bar?

followed by a crotchet A in the LH ? sounds like the same one.
It's a lot more difficult than the Little Sonata, I reckon. FWIW.

Is it this one folks are referring to ? http://www.musicnotes.com/sheetmusic/mtd.asp?ppn=MN0024709

It's not the easiest one!
I have a complete copy of the notebook and there is a very easy piece in G major called "Menuet fait par Mons Bohm". (starts G(minim), A,|F#,D,A,|C,A,F#,|D(dotted minim)|

It looks like you can download the notebook here - http://www.pianopublicdomain.com/downloads/composer/1
