Spangled !

A gentle, Ever-Changing Musical And Visual Patterns,
and ultra-simple interaction make this app a sure winner.

Spangled explores the complex visual and musical structures which emerge from simple independent syncopated rhythms.

Children and Toddlers love it,
and the abstract colors are gentle on the eyes,
while the simple notes of a real, finely-crafted Ukulele are easy on grown-up ears.
Simply touching anywhere on the screen rotates the beautiful pattern
and plucks the 'strings' of the instrument.

Turned one direction, the concentric wheels play the four notes of a Major Chord, and when turned the other way they play a related Minor Chord. The individual notes of each chord are timed independently to produce an ever-changing but always-pleasing rhythm.

High-quality acoustic samples of individual strings of a Hawaiian Ukulele are used, with 5-note polyphony for smooth, easy listening.
