Copperbox revision 96.

Updated Chord module - rudimentary support for reading and printing guitar chords and building chords from interval patterns. Minor updates to other modules in Bala.Base, also minor updates to Bala's tests.

Copperbox revision 95.

Added ArbitraryInstances module for QuickCheck testing.

Sometimes the head revision of Bala hasn't been compilable, which is lax on my part. Even though Bala is still very sketchy, it really ought to build unfailingly as I'm getting close to revision 100 of the whole repository.

Copperbox revision 94.

Some errors had crept in as a consequence of moving code in the BaseExtra module, these should be rectified (particularly MidiPrint should now build again). Plus, some more changes to the Interval module.

I've now tested MidiPrint on OSX and it works properly. It would seem that Binary/ByteString has a problem on Windows XP.

Copperbox revisions 92 & 93.

Revision 92 - The Chord module now has a rudimentary parser for chords in Roman notation.

Revision 93 - Hand-coded Show instance for Roman Chord, to match the Read instance.

Bala

Copperbox revision 91.

More minor changes - the Read instances now use Parsec (as its more forgiving than ReadP).

The Triad module has been renamed to Chord.

Bala

Copperbox revision 90.

Another minor update to the interval module - Read and Show instances for named intervals:
P5 - perfect fifth
A4 - augmented fourth, etc

Bala

Copperbox revision 89.

Small update to pitch class and interval modules - a new function to calculate interval names and helper functions.
