This may be a well-known bit of notation, but I've not come across it before. A friend is starting out on classical guitar (having strummed folk tunes for years). On one of the pieces she has - plaisir d'amour - is written in classical style with chords implied by the individual notes. Over some of them, though it says 1/2CH. What precisely does this mean? None of my music notation books says anything about such a thing.

If it is something that everyone knows, apologies, but it did not show up in Google search or a search here.

Are you sure that's a letter H at the end. More usual is to see things like 1/2CIV ie. 1/2C<roman numeral>. This means hold a half barre (usually across the 2 highest pitched strings) at the fret indicated by the roman numeral (IV=fret 4 in this case). You might also come across the notation C<roman numeral><number subscript> eg CII₄, meaning hold a barre at fret 2 across 4 strings.

1/2 CH appears nowhere that I can see on the 'net (other than as part of chemical notations or stuff like that).

  Plaisir D'amour
  
  
      A   E7 A       D    A       E - E7
  Plaisir d'amour ne dure qu'un moment,
     D    E7 A    D    A     E7 A
  Chagrin d'amour dure toute la vie.
  
      A    E7 A        D     A      E - E7
  The joys of love are but a moment long,
      D    E7 A      D         A     E7   A
  The pain of love endures the whole life long.
  
       A    E7     A       D       A            E - E7
  Your eyes kissed mine, I saw the love in them shine.
      D       E7 A            D              A    E7     A
  You brought me heaven right then when your eyes kissed mine.
  
     A    E7    A       D       A         E - E7
  My love loves me, and all the wonders I see,
    D   E7  A            D          A    E7    A
  A rainbow shines in my window, my love loves me.
  
      A   E7   A            D          A          E -E7
  And now he's gone, like a dream that fades into dawn,
          D     E7   A            D                 A    E7    A
  But the words stay locked in my heartstrings, "My love loves me."
  
  (repeat "Plaisir d'amour ...")

In some parts of Europe, including Germany the note "H" is what in other places is termed the note "B". (And the term "B" is used for a B flat.)

That may or may not be relevant. It might possibly indicate a C chord adjusted to include a B. (Which means it wouldn't be a C chord, but you know what I mean.)

CH can sometimes mean "Chord". Only part of the chord is played,or fingered.

er...!

There's me thinking dear old Clint had gone too far once too often, and someone had hung, drawn and halved the bugger.

1/2C_xH + nO₂ ==> aCO₂ + bH₂O

Sorry. Couldn't resist it. The subject line looked so much like a chemical formula :-)

Looks like something Django Rheinhardt used to come up with.

Half chorus. At the end, repeat the first line but not the second.

I'd go along with the 1/2 CII theory Mick Pearce suggested, having looked at some of my son's classical guitar music. That sometimes uses II and sometimes CII even in the same piece. I'm not a guitarist myself, so when he gets up I will ask him what he understands by it.

II alone means 2nd position (ie play with the index finger of the left hand positioned at the 2nd fret), CII means a barre at the 2nd fret.

(also in my 1st post it should have read (usually across the 3 highest pitched strings) ).

On those chords that have 1/2CH above them, only play half of the chord (but don't ask me which half).

The only chord notation I find in any of my refs that uses the "1/2" fraction is in The Encylopedia of Picture Chords, compiled by Leonard Vogler, Amsco Publications ©1990.

A table of alternate notations at the back of the book gives:

1/2dim; 1/2dim7; m7(b5); m7(-5) as alternate notations for the chord the book notates as a ^Ø7.

(For those whose font tables may be different than mine, the "raised" character just in front of the last "7" resembles a miniature "phi" or "o-slash.")

The book doesn't give a "name" for the ^Ø7 chord that I can find.

This doesn't appear to be anything likely to be indicated by the marking in question.

I'll note that this book doesn't illustrate a barre form for any of the other chords I saw in a brief scan through.

The "half-barre" suggestion sounds most reasonable. Does a "half-chord" (the literal reading if it is a CH and not a CII) have any meaning to anyone?

Thank you all for the explanation. The music is a photocopy of a photocopy, so it is probably II rather than H.

I think that most likely - 1/2CII would be standard classical guitar notation.

John the chord you mention (m7b5 etc) is usually called half-diminished when given a name like that.
