Make consistent 2-voices per part throughout.

This would then support automatic mapping

• from the 2 staves ("close score") keyboard version
• to 4 stave ("open score") SATB choral setting.

Code for this drafted in prep_bach.

The flexible levenshtein sometimes gives higher values than the normal one, notable values higher than 6. Also, the first call to levenshtein_distance here clearly gives a wrong result.

levenshtein_distance('Herr, nun laß Freide', 'Herr, nun lass in Friede') # 7
flexible_levenshtein_distance('Herr, nun laß Freide', 'Herr, nun lass in Friede') # 8

levenshtein_distance('O wie selig ihr doch, ihr Frommen', 'O wie selig seid ihr doch, ihr Frommen') # 5
flexible_levenshtein_distance('O wie selig ihr doch, ihr Frommen', 'O wie selig seid ihr doch, ihr Frommen') # 10

levenshtein_distance('Lobet den Herren, denn er ist freundlich', 'Lobet den Herren, denn er ist sehr freundlich') # 5
flexible_levenshtein_distance('Lobet den Herren, denn er ist freundlich', 'Lobet den Herren, denn er ist sehr freundlich') # 10

Source has slurs both:

• in correct positions
• also where there should be a tie.

TODO: a new script.

• If “slur”
• If note before = note after
• Remove slur, input tie.
• Optionally not even a tie but a longer note value.

May introduce a couple of errors, but vast majority will be improvements.
