Trygve,

Using chords to analyse classical music is fraught with difficulties. The reason for this is that most of the music that we popularly call 'classical' is composed using a mixture of harmonic principles and rules of counterpoint. 20th century chord theory does not apply.

In the 'classical' system of composing, chords arise as the vertical alignment of melodic movement. Some of these chords have no suitable names in terms of modern chord theory (for example the French or German augmented 6 chord).

Also, because the vertical alignment of notes happens all over the place, on beats and between beats, it's difficult, if not impossible, to simply reduce this to just a single chord that relates to today's popular music. The more complex the classical music, the more impossible this becomes.

Grieg is highly complex and mere chordal analyses is a challenge for all who try to deconstruct it.

That said, you can get BIAB to look more closely at the chords. Rather than simply open the midi file in BIAB which causes BIAB to use 2-beat resolution for chord interpretation, use the 'Import chords' function and set it to 1-beat resolution. It's also important to make sure that you get the various midi channels correct - these will vary from file to file. (see the images below)

When analysing classical music, though, you'll never get the perfect results you are after if you use complex works. With simpler works that are much less rich in counterpoint, the results will be ok but will still require some tweaking.

Hope this makes come sense.
