[Rosegarden-devel] New chord notation system

[Niek v. d. B. <nie...@gm...>]

Dear all,

The branch NewChord contains the first version of a new chord notation system. 
A new EventType ChordLabel represents a chord by a chord id and a pitch.The 
chords are defined in XML files in data/chordnotations. A ChordNotation defines 
both the names of notes and chords, It also defines the chords in intervals.

At the moment there are two notations, Standard and RomanNumbers. Standard is 
the default notation and implements an absolute notation system. This means 
that a pitch=4 is always a E.
RomanNumbers defines chord relative to the key. A pitch 4 is a E in C 
major/minor but a F# in D.

ChordLabels can be entered in the Notation Editor (Tools -> Chord Label, of 
the Eb icon in the toolbar next to the Guitar Chord).

The implementation is not finished yet, no export to Lilypond or MusicXML is 
supported yet (but will be). And there many rough edges but it shows a first 
working example.

Any remarks are welcome.

Best regards,
Niek
