Client: Kids Space Museum, Pasadena, CA

*Explanation of the term "rhythmic":  In this instrument configuration, there is only a single row of [designer] selected pitches.   The goal is simply to create and execute repetitive rhythmic patterns within the limitation of the notes on the marimba.  Tempos, rhythms, and repetitive note combinations are in the control of the performer - just not the pitches.  

The audio examples below demonstrate such rhythmic patterns

check GRAMMER** SCIENCE FACTOID **

This instrument demonstrates that the quality of resonator resonance is based on its column length in relation to its column width.

 

A resonator whose length is twice as long as its width would represent a length-to-width ratio of 1:2

A resonator whose length is four times as long as its width would represent a length-to-width ratio of 1:4.

Therefore: the smaller (skinnier) the resonator width is to its length (1:4) its energy cannot drive or push the surrounding air with much force.  Instead, the energy it creates is small compared to its larger cross-section counterpart, and hence not as loud.

The wider the width to its length (1:2) creates a fatter more substantial resonant tone.  The larger cross-section is able to move more air thus bringing more energy to the eardrum.

What the recording demonstrates is the lower pitched, or longer resonator tone sounds much thinner than its shorter counterparts.

...and, the higher pitched or shorter resonator tones sound much fuller or fatter in sound.
