Music and vibration are some of the most subtle but most essential parts of a brand experience. We live in a modern world where we are immersed in all kinds of frequencies (both sonic, subsonic, infrasonic and supersonic to the human ear).
Taking just hearing as an example, besides vocal input and perception, music can be modified in a variety of ways, the most obvious being using a tuning of A at 432Hz instead of 440Hz.
Conversely digital technology as atomised network participants also operates across multiple frequencies and vibrations, eg. from 2.4Ghz to 5Ghz to miliband. The electromagnetic frequency covers an incredible range of touchpoints for a consumer or staff member. Organisations will need to wisely leverage various resonances to deliver information, illicit emotion as well as monitor perception.
I believe we are entering an era where music and colour are mere slices of an expanse of encounters available to organisations. Again the smartphone, smart devices or even Bluetooth proximity interaction are but forebearers to something much more interactive and inter- and intra-personal.
