Rhythm Definition
Rhythm describes how patterns repeat over time. Rhythm is a combination of variable repeating elements.
Regular Rhythm
Like a heart or song with a steady beat, regular rhythm is created by a series of elements, often identical or similar, that are placed at regular or similar intervals, such as in grids. Simple regular rhythms, if overused, can be monotonous.
Alternating Rhythm
Two or more different motifs may be alternated, such as the black and red squares in a checkerboard; a single motif might be flipped, mirrored or rotated every so many iterations; or the placement or spacing between motifs can be alternated. This is essentially a regular rhythm that has more complex motifs, or meta-motifs. The added variety can help lessen the monotony of a regular rhythm
Flowing Rhythm
Flowing rhythm is created by undulating elements and intervals, bending and curving motifs and spaces. Natural flowing rhythm can be seen in streams and waterways, beaches and waves, sand dunes and glaciers, rolling hills and wind-blown grasses.
Progressive Rhythm
In progressive rhythm, each time a motif repeats it changes a little, transforming and translating in a steady sequence - the motif progresses from one thing to another.
