Re: Short rhythm patterns for imitation task

You could try following the method of Povel and Essens (1985) which has been well-tested and formalised into a model of rhythmic complexity by Shmulevich and Povel (2000). For example, Grahn and Brett (2007) use this approach to generate a set of rhythmic patterns varying in perceptual complexity for use in a neuroimaging study; see Table 1, which shows the rhythmic sequences containing 5-7 intervals at three levels of complexity (metric simple, metric complex and non-metric).
Strictly speaking, though, this is metrical complexity which may not be the kind of rhythmic complexity you are after.

Dear list,

Can anyone suggest a set of short rhythm patterns of varying
complexity for use in a rhythm imitation task with children?
Ideally the patterns would be about 4-7 elements long
and at 2 or 3 levels of rhythmic complexity. They would
hear one pattern at a time and imitate it by tapping
with a drum stick.

If anyone knows of suitable stimuli, especially
batteries that have some published data associated with them,
I would be most grateful.

Thanks,
Ani Patel
