   a.improperParentage;

   [ FoscRhythm.new ]

parentageRatios

A sequence describing the relative durations of the nodes in a node’s improper parentage.

The first item in the sequence is the preprolated_duration of the root node, and subsequent items are pairs of the preprolated duration of the next node in the parentage and the total preprolated_duration of that node and its siblings.

Returns array.

prolation

Prolation of rhythm tree node.

Returns multiplier.

1. Example

   b = FoscRhythm(4, [-3, 2]);
   a = FoscRhythm([3, 4], [1, 2, b]);
   a.prolation.pair;

   [ 1, 1 ]

   b.prolation.pair;

   [ 3, 28 ]

prolations

Prolations of rhythm tree node.

Returns array.

1. Example

   b = FoscRhythm(4, [-3, 2]);
   a = FoscRhythm([3, 4], [1, 2, b]);
   a.prolations.collect { |each| each.pair };

   [ [ 1, 1 ] ]

   b.prolations.collect { |each| each.pair };

   [ [ 1, 1 ], [ 3, 28 ] ]

properParentage

1. Example

   b = FoscRhythm(4, [-3, 2]);
   a = FoscRhythm([3, 4], [1, 2, b]);
   a.properParentage;

   [  ]

   b.properParentage;

   [ FoscRhythm.new ]

startOffset

The starting offset of a node in a rhythm-tree relative to the root.

Returns a FoscOffset.

1. Example

   a = FoscRhythm([1, 1], [1, [1, [1, 1]], [1, [1, 1]]]);
   a.do { |node|
       node.depth.do { Post.tab };
       node.startOffset.pair.postln;
   };

   [ 0, 1 ]
     [ 0, 1 ]
     [ 1, 3 ]
       [ 1, 3 ]
       [ 1, 2 ]
     [ 2, 3 ]
       [ 2, 3 ]
       [ 5, 6 ]

stopOffset

The stopping offset of a node in a rhythm-tree relative to the root.

Returns a FoscOffset.

1. Example

   a = FoscRhythm(1, [1, [1, [1, 1]], [1, [1, 1]]]);
   a.do { |node|
       node.depth.do { Post.tab };
       node.stopOffset.pair.postln
   };

   [ 1, 1 ]
     [ 1, 3 ]
     [ 2, 3 ]
       [ 1, 2 ]

   a.prGetPreprolatedDuration.str;
   b = a.([1, 16]);
   FoscVoice(b).show;
