- How about endowing Encore with a new tool that allows users to stretch or shrink the metric makeup their scores?
Sometimes I want to do this for scholarly reasons ... other times it's to simplify a score for a student.
Here's an example score, an Allemande by J.S. Bach. Though this piece is rather easy to play, it's challenging for kids to read in it's original form—those 16th notes easily scare and confuse them. I rewrite such scores for kids in a simpler metric framework ... so they can play beautiful music they might otherwise find unapproachable.
Here's the Bach Allemande in its original metric setting:
Here's a metric simplification of the same piece -- a "duration doubling" transformation. The length of every note is doubled; every measure in the previous score becomes two measures in the new score:
If I'm not mistaken, the logic required to produce this transformation is quite simple:
- To double note values (i.e. quarters become halves, etc.), change the note-start and note-end to 200% of their current values.
To halve note values, change the start and end to 50% of their current values.
Of course, Encore would also need to recalculate the measure assignments, just as I did manually in the example above.
