Corpus: Incorrect meters #5

Open jsundram opened 11 years ago

jsundram commented 11 years ago

There are several of Haydn's quartets where the meter is incorrectly listed as 4/4 when it is in fact in cut time (2/2).

This is a problem with the underlying data.

It happens in the following 18 movements: 020_5m4, 020_6m2, 033_3m1, 033_5m2, 033_6m2, 050_1m1, 050_2m2, 054_2m1, 055_1m1, 055_1m4, 064_1m1, 064_6m1, 074_3m2, 076_3m2, 076_5m2, 077_1m1, 077_1m2, 077_2m1.

Between the headers of the Haydn quartets not matching what Walter Hewlett said they would be, MuseData §1: Composite File Organization vs reality: 

# here's the header of Op 020_6m2:
526 
20,6  2   
Richault, Vol.4, Quatuor 6, p.91d, Paris; HV III:36                 
.
.
4 1    
79 4 96 24 
4 4 2

... and the music21 musedata class doing some interesting parsing, it's not entirely clear what's going on here.

More research is required to figure out how to best fix this.
